  • Climate Relationships between Air Temperature and Water Temperatures in
           the Different Limnetic Zones of Lake Ladoga

    • Free pre-print version: Loading...

      Abstract: Based on an extensive database, it is shown that for different limnetic regions of Lake Ladoga a temperature hysteresis phenomenon occurs for the period of open water from May through November. The features of heating and cooling of both the water surface and the integral water column temperature in six different zones of the lake have been revealed, depending on the air temperature of the near-surface layer. The approximation of dependences between these parameters, the second- and third-degree polynomials, has shown that there are stable, meaningful relationships (p < 0.05) between them, with the determination coefficient of 0.8–0.9. Analytical dependencies allowed calculation of the increase in water temperature when the air temperature changes by one degree. On Lake Ladoga, a dependence of the rate of change in water surface temperature on air temperature is found. The biggest changes occur during the heating period. In August, with maximum air temperatures, the rate of increase in water surface temperature, especially in the deep-water area, exceeds the rate of increase in air temperature. Canadian limnologists obtained similar results on Lake Ontario. Two important periods have been distinguished when the lake cooled down: the first one occurs when the surface temperature has a constant value with the minimum spatial dispersion; the second one occurs when the entire water column of the lake has the same water temperature with minimum spatial dispersion. These periods and values of water and air temperatures can serve as climatic norms in climate studies. Climatic changes in air temperature will affect the increase in water temperature in different ways in different seasons and in different areas of a large lake.

  • The Trends of the Standardized Precipitation and Evapotranspiration Index
           (SPEI) in Turkey

    • Free pre-print version: Loading...

      Abstract: This paper examines drought trends in Turkey due to climate change. Therefore, forecasting of periods of drought, which is one of the major negative side effects of climate change, is urgent. The authors use data on drought indicators according to the SPEI (Standardized Precipitation and Evapotranspiration Index) for the period from 1901 to 2015 obtained at intervals of 1, 3, 6, and 12 months. The data have been processed by several statistical tests: the Mann–Kendall test to determine the direction and significance of the trend, the Theil–Sen estimator to assess the trend slope coefficient, and the Pettitt test to determine the most probable year of change. The period under study is divided into two intervals (1901–1981 and 1982–2015), which are compared. The GIS program is used to isolate spatial characteristics from the results we obtained. It is concluded that Turkey is divided into two main zones of drought trends. The largest one allocated to the northern regions is characterized by an increase in moisture, and a decrease in moisture is observed in the southern regions. The trend towards dry periods was more significant until 1981, but the situation has changed since 1981 due to the trend towards excess moisture, except for southeastern Turkey, where a trend towards droughts persists.

  • The Formation of the Species Structure of Plant Communities on the
           Northern Boundary of the Krasnoyarsk Forest–Steppe over the Last 6000
           Years

    • Free pre-print version: Loading...

      Abstract: The results of a paleobotanical (paleocarpological) layer-by-layer study of three peat sections located near the Pogorel’skii Bor experimental station operated by the Institute of Forest SB RAS (the interfluve of the Buzim and Sukhoi Buzim rivers) are presented. The study area is located in the transitional zone between subtaiga grassy small-leaved and coniferous forests and the Krasnoyarsk nonzonal forest–steppe. The climate of the region is extreme continental, moderately warm, and insufficiently humid. The objects of paleocarpological analysis were macrofossils (macro-residues of fossil plants (generative and vegetative parts of plants). Data from each section were used to construct carpograms (histograms showing the quantitative distribution of macro-residues in the identified fossil complexes, in accordance with the section stratigraphy). As a result of a comparative analysis of the species composition of paleocarpological complexes taking the data on radiocarbon 14C dating (nine dates) into account, the evolution of the vegetation cover of the territory of Pogorel’skii Bor was reconstructed by using hypsometric levels and seven time intervals, starting in the second half of the Atlantic period of the Blytt-Cernander chronological scheme of the Holocene. On this basis, digital maps of paleophytocenoses were compiled. Analysis of the formation of vegetation over the last 6000 years has shown that in the first half of the period the birch–larch forest–steppe with an alternation of shallow lakes prevailed on the territory. The onset of cooling and humidification (5000–3500 BP) contributed to the development of a subaiga forest-vegetation complex with the involvement of dark coniferous species. The subsequent warming (3500–3000 and 1300–800 BP) contributed to the return of forest–steppe and the development of steppe complexes. The leading tree species in the first half of the period were Siberian larch and birch, and, later, Scotch pine. A decrease in the role of larch, and an enhancement of the position of pine and steppe elements in forest phytocenoses during a later period (300 BP) were caused by climate change, as well as by the increased influence of the anthropogenic factor. The regional features of the paleoclimatic regime of Pogorel’skii Bor forest in the latest Holocene are highlighted.

  • Synchronism of Variations in the Annual Runoff of the Largest Rivers in
           the Asian Part of Russia

    • Free pre-print version: Loading...

      Abstract: The synchronism and asynchrony of variations in the annual runoff for the 18 largest rivers (153 river pairs) in the Asian part of Russia have been assessed using a novel original technique. The technique is based on taking three groups of river water discharge (low-, average-, and high-water years) into account and on the numeric rating of the runoff in the years compared. The runoff of the rivers is assigned to a particular group of water discharge by using its long-term average annual value. The years in which the runoff was less than 0.95 of its long-term average annual value are assigned to the low-water years; when it is more than 1.05, they are added to the high-water years. The average-water years include the runoff values from the 0.95–1.05 interval of the long-term average annual value. The runoff in the low-, average- and high-water years is identified by numbers 1, 2, and 3, respectively. A comparison of water discharges is made for all 153 pairs of river basins over the correlative observation periods under investigation. The years of identical water discharge (1–1, 2–2, 3–3) are assigned the number 1; the years with opposite water discharge (1–3, 3–1) are characterized by the number –1, and the years of similar water discharge (1–2, 2–1, 2–3, 3–2) are identified by the number 0.5. For each pair of rivers, the numeric sum expressed in fractions of the total period of observation is calculated, which is the parameter of synchronism (asynchrony) of runoff variations. For 18 pairs of the river basins, the values of the synchronism parameter are equal to or more than 0.5. For these pairs of the rivers, it is determined that the average contributions of the low-, high- and average-water years to synchronism are 45.1, 36.3, and 10.7%, respectively. The years of adjacent discharges increase the synchronism parameter by 29.2%, while the years with opposite discharges decrease synchronism by 21.3%. The synchronism is also assessed by using the correlation method.

  • Assessment of the Features of the Economic and Geographic Position of
           Towns in the Southern Region of Kyrgyzstan

    • Free pre-print version: Loading...

      Abstract: Abstract—The necessity of developing measures for the regional development of Kyrgyzstan, increasing the economic potential, and improving the infrastructure for industrial and social purposes is shown. In this regard, the development and revival of the economies of towns, including small ones, are considered as a priority direction in the implementation of these goals. It was revealed that the small towns of the country, due to the diversity of historical formation, economic-geographic location (EGP), and socioeconomic values, differ from each other. Their main problems are the lack of economic assets, the scarcity of the city budget, remoteness from large centers, unemployment, and a decrease in living standards. The necessity of a comprehensive study of the potential and development prospects of small towns has been substantiated; a thorough analysis of their economic and geographic position is considered as the most important. As a result, the individual features of these towns were revealed. For this purpose, a study was made of the economic and geographic positions of small towns in the southern region of Kyrgyzstan concerning their status regarding transport, industrial, agricultural assessment, recreational, market and innovation relations. The results showed that the towns in the region range from 3.8 (Kochkor-Ata) to 2.3 points (Sulukta) according to the degree of EGP by components. To generalize these series, the towns were combined into three groups: those with the most advantageous economic and geographic location; those with a favorable economic and geographic location; and towns with a relatively favorable economic and geographic position. It was shown that the degree of profitability of the economic and geographic position of small towns in the region does not have a territorial sequence, i.e., it is not determined by the “center–periphery” pattern. The study enabled the determination of the general potential for the development of the urban economy, planning the construction of infrastructure facilities, and revival of the industrial sector of the economy as a city-forming factor.

  • Tritium in Natural Water of the Lena River Basin

    • Free pre-print version: Loading...

      Abstract: The long-term dynamics of tritium content in atmospheric precipitation and in surface and ground water of the Lena River basin is characterized on the basis of new data obtained in 2019 and 2020 and historical information. The relationship between the tritium content and the concentration of dissolved chemicals is analyzed. In 2019 and 2020, during the periods of winter and summer low water, 44 water samples were taken from the Lena River, its large, medium, and small nonfreezing tributaries, intrapermafrost and subpermafrost groundwater, snow cover, and liquid precipitation. Data on tritium concentrations in the upper and middle Lena River and its tributaries are given for the first time. The element content in samples from river water, snow cover, and rain corresponds to its long-term descending curve. The tritium concentration in river waters during the winter low-water period is smaller than in the summer period, when its content in the rivers approaches its values in atmospheric precipitation. This testifies to the contribution of groundwater to river recharge in spite of the wide spread permafrost. Statistically significant correlations of the tritium content with the redox potential and the contents of bicarbonate, lithium, and sodium ions, total dissolved solids, and pH have been revealed.

  • The Influence of the Resource Base on Innovation Development of
           Oil-Producing Regions of Russia

    • Free pre-print version: Loading...

      Abstract: Abstract—This article considers the decline trends in the structure and quality of the Russian oil-producing regions and systematizes the criteria for distinguishing the category of hard-to-recover oil reserves in the domestic literature. We investigate the characteristics of the resource base of hydrocarbons and their impact on the innovative development of the Russian oil-producing regions. The authors of this article have collected a unique data base necessary for a comprehensive study of resource regions, which includes information about total recoverable reserves, the share of small and very small deposits, the average size of the deposit, and degree of exploration are among the resource factors (the factors of the fluid property included the contribution from dense, sulphurous and viscous oil, and the oilfield factors involved water cut and the degree of depletion). Our analysis also included the factors of innovative regional development: the share of innovative goods in the volume of shipped products, the work done and services rendered, the share of technological innovation costs, and the share of internal research and development costs for the gross regional product. Thus, the hierarchical clustering method has been used to classify the oil and gas regions of Russia according to the quality, to the structure of the resource base, and to the level of innovative development. Calculations identified three clusters (groups of regions): one cluster included regions with a high degree of innovation and a high degree of hard-to-recover reserves, another cluster involved regions with a medium degree of innovation and a low degree of hard- to-recover reserves, and a third cluster included regions with a low degree of innovation and a moderate degree of hard-to-recover reserves. The current study confirmed the hypothesis that a low quality of the resource base of hydrocarbons in the Russian oil-producing regions stimulates innovative development. The results of the research indicate that the production of hard-to-recover oil has an extensive innovative component, which has a multiplicative effect on the related industries and economies of the regions as a whole.

  • The Environmental Conditions in Irkutsk, Ulan-Ude, and Ulaanbaatar

    • Free pre-print version: Loading...

      Abstract: — Geoenvironmental studies of urban centers of the Baikal region are aimed at identifying the details of human impacts on the environment in this area in order to then find rational solutions to environmental problems of the region and improve the quality of life of its population. This article characterizes the environmental condition of the cities of Ulaanbaatar, Ulan-Ude, and Irkutsk and analyzes the relationship between socio-economic conditions and environmental problems of the territories. The data used in the study consists of statistical and archival materials, cartographic and literary works, and data from experimental observations. The urban centers of the Baikal region are characterized by different socio-economic conditions, but share some common features of modern agglomerations: an intense population concentration in capital cities, problems with utility lines, and increased environmental tension and discomfort. The analysis revealed a heavy environmental burden of the fuel and energy complex and motor transport. The environmental situation in the cities is also significantly influenced by factors, such as atmospheric circulation, the condition of natural waters, and the conditions for migration of chemical elements through the soil. An assessment of the level of human impact on components of the environment revealed extremely unfavorable conditions for self-purification of the atmosphere in Ulan-Ude and Ulaanbaatar, with the highest level of air pollution recorded in Ulaanbaatar. The highest level of soil pollution is observed in Irkutsk; it is due to large-scale industrial emissions and the fact that the soil of the territory has characteristics favorable for accumulation of pollutants. Ulaanbaatar is experiencing problems with the quality of water resources and the drinking water supply. Anthropogenic pressures on the environment of the cities create health risks for the population due to the entry of toxic pollutants into the air and into water bodies.

  • The Difference in the Classical Geopolitics of Countries of the
           Continental and Oceanic Types and the Position of Modern Russia

    • Free pre-print version: Loading...

      Abstract: This article deals with the categorization of Russia as the continental type of country that is typical of classical geopolitics and the concepts based on its approaches. An analysis has been made of the main aspects of continentality of countries: the territorial, population distribution, and activity aspects. A number of indicators have been proposed to reflect these aspects. The resulting sample of countries, including Russia, have been characterized according to the degree of continentality based on these indicators. It is shown that in terms of transport and geographic continentality, the number of seaports, the cargo turnover of the country’s largest port, and the location of the capital city relative to the sea, Russia should be classified as a continental country. In terms of the ratio of sea and land borders, the potential of the Navy, and the number of merchant ships and fish catches, Russia should be assigned to the oceanic type of country. It has been determined that integrally Russia can be assigned to the transitional continental-oceanic type. A positive correlation was found between the number of merchant ships per capita and gross domestic product per capita, exports per capita, and life expectancy. This correlation shows (confirms) that the more continental a country is, the less economically developed it normally is. It has been noted that within the framework of classical geopolitics the classification of Russia as a continental country is associated with the concept of the difference between “sea” and “land,” which gives rise to international conflicts. A departure from the idea of explaining the conflict between Russia and the West by these geographical factors also entails a rejection of the image of Russia as a purely continental country. The use of the military–political and economic advantages of both the sea and continental location was characteristic of Russia in the past and is relevant at present.

      Abstract: The methodology of economic valuation of ecosystem services of the marine environment has been considered, which implies identification and valuation of the benefits obtained by humans from using marine ecosystems. It has been found that the previous research disregarded and did not assess the assimilation potential of port water areas, which consists in the absorption and dispersion of pollution that arise in the course of port activities. A methodological approach has been proposed for its assessment as well as an algorithm for calculating the rent-based assimilation potential by the amount of saving of expenses of economic entities that they do not pay to compensate for the damage caused or do not invest in its reduction and prevention, that is, by the amount of environmental damage caused by sea-going ships and port activities. The cost of the assimilation potential for the largest ports of Russia, the European Union (EU) and China has been calculated based on the monetized metrics of environmental damage applied in the EU countries and the indicator of pollutant emissions per 1 million tons of cargo transshipments carried out in ports, as well as the costs of cleaning polluted water discharged by ships. The latter value has been calculated only for the ports of Russia.

  • Analysis of Remote Spectral Indices in the Study of Successional Changes
           of Tundra Vegetation in Postagrogenic Biogeocenoses

    • Free pre-print version: Loading...

      Abstract: A comparative analysis of remote spectral indices has been carried out during the study of changes in the vegetation cover in the postagrogenic biogeocenoses of the Bolshezemelskaya tundra. Successional changes in the species composition of vegetation have been considered to estimate the dynamics of the spectral indices in the meadow biocenoses throughout the agricultural and postagrogenic periods. The spectral characteristics and species composition of vegetation in the surrounding undisturbed biocenoses were used as background indicators. Compared to the surrounding background sites, meadow biogeocenoses used for agriculture had relatively high indices, characterizing the moisture and photosynthetic activity of plant phytomass (NDVI, LWCI, NDMI, and channel B5). Changes in the amount of dead biomass were estimated using the PSRI index, the values of which were minimal during the period of agricultural use of the meadows with regular haying. During self-recovery succession in postagrogenic biogeocenoses, the values of the spectral indices gradually reach the level characteristic of the surrounding background sites. During the postagrogenic period, the LWCI, NDMI, and NDVI values gradually decrease and the values of PSRI and spectral channel B3 increase in meadow biogeocenoses. During the postagrogenic period, sown grass herbage thins out in meadow biogeocenoses, a shrub layer is formed, and species that penetrate from the surrounding communities become dominant and subdominant. The self-recovery of tundra vegetation in postagrogenic biogeocenoses was activated during the period of current climate warming. The effect of climate on the spectral indices was assessed based on the statistical relationships between the values of the climate characteristics and spectral indices in postagrogenic and background biogeocenoses.

  • The Vegetation Resistance of Geosystems in the Depressions of Northeastern
           Cisbaikalia to the Pyrogenic Factor

    • Free pre-print version: Loading...

      Abstract: Abstract—The study of vegetation stability remains an important and poorly developed issue of geobotany. Results from studying of a study of resistance to the pyrogenic factor of plant communities of vegetation cover of the North Baikal and Upper Angara depressions are presented. In recent years, fires have become catastrophic in Siberia, as well as on the territory of the country as a whole; therefore, pyrogenic impact is one of the main negative anthropogenic factors. We suggest an original technique for determining the parameters of vegetation resistance to the pyrogenic factor, based on assessing ignitability. The susceptibility to fire of both individual plant species and plant layers of cenoses, as well as the degree of damage by fires, have been comprehensively studied, with regard for the mesoclimatic conditions and areal distribution throughout the territory. It was established that the resistance of the communities can vary according to on their hierarchical rank. As a result of this research, a legend and a medium-scale map of the vegetation resistance in the region to the pyrogenic factor have been generated. It was revealed that the most stable communities are sparse alpine tundras, alpine meadows and meadow-swamp communities of the Upper Angara floodplain and wet forests of mountain valleys. The medium-stable cenoses include tundra watersheds and sloping summits with well-developed shrub-lichen cover, sparse communities of Pinus pumila, small-leaved forests, steppe slopes and forest communities of the floodplain. The lowest degree of stability is typical for closed P. pumila thickets, subgoletz dark coniferous-larch forests, and mountain taiga dark coniferous forests, as well as for pine forests of the submontane-depression belt. One important characteristic of the stability of the communities is the duration of recovery of the primary (conventionally primary) state. It is shown that the accessibility of natural communities to humans significantly affects the resistance of vegetation to the pyrogenic factor, because this greatly increases the likelihood of fire in any of these cenoses.

      Abstract: Abstract—Experimental investigations were made into the basicity–acidity indices (pH) and soil biochemical activity (SBA) in the industrial city of Ust’-Ilimsk in conditions of Eastern Siberia. A cartographic representation of the distribution of values of integral indicators of soils in the city is presented for the first time. The significance of the method of mapping urban soils that are experiencing urbanization and technogenesis is emphasized. The investigation was made by using the express method of determining the soil biochemical activity. In addition to this indicator, pH conditions of soils were identified. The study encompassed the main functional zones of two parts of Ust’-Ilimsk: the Old Town (Levoberezhie) and the New Town (Pravoberezhie). The neutral and weakly alkaline soils are of widespread occurrence on the territory. The pH values vary from 7.4 to 7.8; in the control soils, they vary from 6.3 to 6.9. A significant area of the city (43.9%) is occupied by weakly alkaline soils. The level of soil biochemical activity permitted us to categorize the soils as active and very active. The proportion of very active soils makes up 32.9% of the total territory of the city. This indicates a trend of ecological regression, namely a loss of a biogenic element, nitrogen. The study revealed trends of a weak but positive dependence of SBA on pH. The coefficients of approximation are positive and vary, according to the zones of the city, from 0.2 to 0.5. The absolute and relative distribution of the areas with pH and SBA values is shown. A comparative analysis of data revealed a difference of the Ust’-Ilimsk soils from the soils in other cities of the Angara region.

  • The Patterns of Seasonality of the Suspended Sediment Load along the
           Braided Channel of the Lena River

    • Free pre-print version: Loading...

      Abstract: The features of the suspended sediment load along the 200-km braided channel of the Lena River from the city of Pokrovsk to the Aldan River mouth (upstream of the Aldan braiding) are described in detail (30-m resolution) based on water-sediment concentration modeling, using the collection of Landsat images for the period of 1992–2018. It is shown that large anabranching river reaches correspond to changes of the system of sediment transport and accumulation, manifesting themselves as the predominance of the occurrences of positive (increase) or negative (decrease) ΔS0 values (where ΔS0 stands for suspended sediment-concentration budget). The conditions of a longitudinal decrease in suspended-sediment concentration along the braided reach of the Lena River are characterized by high water discharges (>20 000 m3/s) and are associated with sediment accumulation in riffles and floodplain areas. It has been revealed that a significant role in the longitudinal decrease in water-sediment concentration is played by lateral floodplain branches, which accumulate a part of the incoming suspended sediments and exert a dilution effect on the sediment flow downstream of the confluence with the main channel. Cases of a longitudinal increase in the water-suspended sediment concentration are typical for lower water flow rates (<20 000 m3/s) and are related to increased bank thermal erosion in summer and erosion of riffles during a low-water period. A combination of the grid of suspended-sediment concentration, velocities, and channel depths with a 30 × 30-m resolution (more than 20 000 cells) for low-water conditions revealed a dependence of the local suspended-sediment concentration on the transporting capacity of the flow, which was determined for particular verticals. A correspondence between the regime of certain reaches in different phases of water regime is observed. It indicates the mutual influence of the directedness of mass exchange and channel morphology. The transformation of distribution systems of suspended sediments may be interpreted as one of the self-regulation mechanisms in the channel system. Complex systems of sediment flow distribution along the channel of a large river reflect the opposite directions of erosion-accumulation processes caused by bends in the longitudinal profile.

  • The Bottom Relief Features of the Basins of Lake Baikal

    • Free pre-print version: Loading...

      Abstract: — Based on analyzing bathymetric material obtained in different years by using high-precision geophysical equipment featuring multi-beam echo sounders, the main bottom relief features of the South, Middle, and North basins of the Baikal depression have been considered. It has been established that ridge-ravine forms and canyon valleys are well developed on the underwater slope of all depressions. The valleys of the canyons of the Middle and South basins reach their maximum maturity, which is associated with a longer history of the evolution of these basins. The canyon valleys are highly sinuous there, which is associated with the peculiarities of the underlying substrate and fault tectonics. The canyons of the western side of the Baikal depression are predominantly tectogenic in origin, are short, and show a significant steepness of the longitudinal profile; their valleys are mostly rectilinear. The underwater slope along the eastern coast of the North basin and its abyssal surface are complicated by a set of glacial landforms: moraine swells and fan cones formed by turbidite flows during interglacial periods. On the coast, they are continued by very extended swells of lateral and stadial moraines. Tectogenic scarps are widespread in the lower parts of the underwater slopes and usually run parallel to the coastline. It has been established that the flat-convex surfaces of the deltas, which sometimes reach the abyssal surface of the lake, are a very characteristic form of the sloping relief of the South basin. Numerous outcrops of Miocene–Pliocene limnic sediments on the eastern coast of the Middle basin, and the nature of their spatial arrangement suggests that the sedimentary strata of the underwater slope of this basin may be of the same age and be genetically homogeneous with terrestrial strata, which are Miocene–Pliocene in age. Similar deposits of the Tankhoi field on the southern coast of the depression also extend far into the water area of the lake, which supports the existing points of view about the similar history of the development of the South and Middle basins.

  • Transformation of Irrigated Lands in Regions of Russia during the
           Postsoviet Period

    • Free pre-print version: Loading...

      Abstract: This paper examines the transformation of irrigated lands in regions of Russia over the course of a long period. In 1990–2018, the area of irrigated lands decreased nationwide from 6.2 to 4.7 million ha. In some constituent entities of the Russian Federation, the area of irrigated lands decreased by 4–14 times; while in two of them, it increased by 35‒40%. In 2018, 735 000 ha (16%) of irrigated lands were not used in agriculture, primarily due to soil salinization and waterlogging; back in 1990, the share of unused lands was only 3.7%. It is concluded that agricultural use of idle irrigated lands should be resumed as soon as possible to enhance food security and increase exports of foods and agricultural raw materials. The ongoing transformations in the structure of irrigated agricultural lands in Russia are not that perceptible at the federal level; however, in some regions, they are quite noticeable. The share of forage crops in irrigated crop rotation systems should be increased to enhance soil fertility and boost the production of forage and livestock products. A steady deterioration trend in the ameliorative condition of irrigated lands has been observed in the country in recent decades. An especially unfavorable situation is noted in the Northwestern Federal District. The area of lands that require capital improvements to raise the technical level of their irrigation systems has increased dramatically. The area of actually watered irrigated lands has decreased from 4.9 million ha in 1990 to 1.4 million ha in 2016. Concurrently, high-efficiency drip irrigation systems are rapidly developing. Domestic manufacturers and joint ventures should boost the production of drip irrigation systems in Russian regions. This study presents data that indicate a revival in the production of domestic sprinkling equipment that is not inferior to foreign counterparts and costs much less.

  • The Landscape Structure of the Gede–Pangrango Stratovolcano (West
           Java, Indonesia)

    • Free pre-print version: Loading...

      Abstract: Abstract—The structure of the Gede–Pangrango Stratovolcano, the highest volcano on Java Island, has been analyzed. Based on landscape mapping and the field observations, geographical data reflecting the spatial structure, relationships, interaction, and distribution characteristics of different-ranked ecosystems have been obtained. The influence of the equatorial climate, volcanism, altitudinal zonation, and anthropogenic impact on the formation of the structure of the volcanic landscape are shown. It was established that an increase in the altitude on the slopes of Gede–Pangrango Volcano resulted in an increase in the areas of subclasses of the steep and vertical slopes, as well as in an increase in the slopes of moderate steepness. At the same time, the share of subclasses of plume slopes, gentle slopes, and valley bottoms has decreased. These are almost absent in the summit belt of the volcano. In this case, the composition of vegetation formations becomes simpler and floristic elements of higher latitudes appear, due to a decrease in the average daily temperatures. At present, the anthropogenic factor has a significant impact on the landscapes of the volcano. As a result of the plowing of land and the construction of roads and settlements, the natural complexes of gentle slopes and their aprons have been strongly transformed. The slopes of moderate steepness are less affected by the anthropogenic impact. The subclasses of the steep and sheer slopes, as well as of valley bottoms, have mostly preserved their natural features. The anthropogenic disturbance of ecosystems decreases with an increase in altitude, which is due to a decrease in heat supply as well as to an increase in volcanic influence and intensification of erosion processes. This makes agricultural activity, the construction of roads, and the location of settlements difficult, and on steep slopes, even impossible. The reserve status of the territories in the middle and upper altitudinal belts of the volcano is favorable for the preservation of natural landscapes.

  • The Response of Glaciers to Global Warming in the Mountains of Eastern
           Siberia, Mongolia, and Northwest China

    • Free pre-print version: Loading...

      Abstract: Abstract—The use of diverse, multi-temporal satellite space information has become the main approach in investigating the current status of mountain glaciers. We have accumulated large archives of satellite images of snow–glacial systems on Earth with different spatial resolutions over the past 50 years. Together with the previously created topographic maps displaying glaciers, glacier catalogs, special maps, and atlases of ice and snow, they provide data to determine changes in areas, lengths, volumes, and altitudes of glaciers during the current climate warming. In 1986, the World Glacier Monitoring Service (WGMS) was founded to monitor glacier fluctuations in different regions of the Earth. However, the number of observation sites is limited. The Global Ground Glacier Observing Network mainly includes those glaciers where we previously conducted ground-based studies of glacier front fluctuations, mass balance measurements, measurements of meteorological parameters, ice flow velocities, and ablation features. To identify regional differences, different altitude and plan locations, the influence of permafrost, and the background landscape environment requires that data on a larger number of glaciers be analyzed. Therefore, groups of researchers from Irkutsk and Beijing began to study the dynamics of glaciers in the inland regions of Eurasia within the framework of international projects. Several glaciers were selected in the mountains of the south of Eastern Siberia, the Mongolian Altai, and the eastern part of the Tien Shan. We recorded current glacier fronts and their elevations. The lengths and areas of glaciers in the early 1970s and early 2000s and their current state were determined. In recent decades, some connections between the dynamics of glaciers and changes in meteorological parameters have been revealed.

  • Earth Insolation and Tendencies of the Variation of Alpine Ice Resources

    • Free pre-print version: Loading...

      Abstract: On the basis of high-precision astronomical ephemeris with a high spatial and temporal resolution, the insolation of the Earth at the upper boundary of the atmosphere was calculated for the period from 3000 BC to 2999 AD. The differences from the earlier calculations of insolation are associated with the initial astronomical data and new calculation algorithms. In our calculations of insolation, the time interval of 5999 years and the entire surface of the Earth have been covered in detail. The Earth is not identified with a sphere, but is approximated by an ellipsoid. Previously, calculations of high-frequency variations in insolation were performed for individual parallels (in space), and in time for four or five separate points of the year (equinoxes, solstices and, sometimes, points with a geocentric longitude of 120 degrees). We have calculated insolation for the surface of latitudinal zones at 1° latitude and time intervals equal to 1/360 of the duration of a tropical year (approximately a day). Correlation analysis of the total mass balance of alpine glaciers (for the period from the balance years 1948/1949 to 2009/2010) with summer and winter insolation and summer, winter and annual insolation contrast of the northern hemisphere, which in a summarized forms (by regions of heat source and sink) reflects long-term changes in the meridional insolation gradient. It has been determined that the long-term variability in the total mass balance of alpine glaciers on average (for glaciers covered by balance observations) is accounted for by the trend at 94.3%. The trend to a reduction of alpine glaciers by an average of 90.6% is determined by the annual insolation contrast, which reflects an increase in the meridional heat transfer, as determined by an increase in the meridional contrast of radiant energy (on the Earth’s surface, excluding the atmosphere). Based on the close correlations determined by using a regression model, a forecast of the total mass balance of glaciers up to 2050 AD was made, which indicates a catastrophic development of the degradation of the modern glaciation of the Alps.

      Abstract: The formation features in the ethnic structure and settlements of Barguzin Cisbaikalia across the territory of the modern Barguzinskii and Kurumkanskii districts of the Republic of Buryatia are considered. On the basis of archival sources and field research material, the impact of socio-administrative transformations, methods of economic activity, and the characteristics of the natural environment on the placement of the newcomers and old-time population are revealed. The adaptive features of local communities are shown, which led to sustainability of the traditions of nature management and everyday interethnic contacts. The nature of the settlement of the territory and the formation of a network of settlements in different historical periods had its own characteristics and, at the same time, was largely determined by the degree of the preservation of the complex of nature management traditional for the ethnos: agricultural-commercial, animal husbandry-commercial, hunting-commercial and fishing nature management with a number of transitional options that formed in the course of constant interaction of ethnic groups in the region. It was found that stability and continuity in the organization of the human habitat were characteristic for the study area and the peoples inhabiting it. The distribution of settlements, as well as temporary and permanent camps in different historical periods reflected the state of the ethnocultural landscape and determined the location of its functional zones and areas, as well as contributing to the formation of the identity of the local population.
