The advantages of a quantitative assessment of the spatial and temporal variability of the boundaries and volumes of ravines using modern means and methods of aerial photography from an unmanned aerial vehicle (UAV) are substantiated, in contrast to traditional survey methods (linear method of benchmarks, tacheometric, aerial and space photography, laser scanning). The erosion zoning and mapping of linear and gully formations on the territory of the Kuitunka, Tarbagataika, and Kunaleika river basins (Selenga middle mountains) are carried out. The reanalysis data were used to assess extreme meteorological events leading to the acceleration of erosion processes. Paleontological material confirms the long duration of erosive-accumulative processes in the Nizhnyaya Bulanka depression. High-accuracy multi-temporal orthophotomaps and digital elevation models of Bulanka gully using unmanned aerial vehicles were produced. The method of quantitative estimation of gully formation rates is offered, which allows estimating with high accuracy the change of area and volume characteristics of erosive forms.

Climate change and anthropogenic activity in the Republic of Buryatia aggravate the processes of desertification and land degradation. The territory of Buryatia was zoned according to the aridity index based on ENVIREM climate data with a high spatial resolution. Long-term changes in the vegetation cover in arid and humid zones are quantitatively assessed based on a combined study of the time series of the normalized-difference vegetation index (NDVI) with the Advanced Very High Radiation Radiometer (AVHRR), meteorological series of the NCEP/NCAR Reanalysis data set, and field studies. Maps of the spatial distribution of NDVI linear trends and precipitation for 1982–2015 (with the differentiation of the wet (1982–1999) and dry periods (2000–2015)) have been constructed. During the wet period, positive NDVI trends are observed for almost the entire republic, while the dry period is characterized by a significant increase in negative trends of the vegetation index. A positive correlation between the Selyaninov hydrothermal coefficient and NDVI is observed for intermountain steppe basins, while it is negative for forest landscapes. The dynamics of the NDVI for steppe vegetation is more dependent on precipitation, while the dynamics of the NDVI for forests is more significantly correlated with temperature. Reforestation, postpyrogenic succession, the bushing of fallow lands, and other factors determine the growth in the NDVI. Negative NDVI trends are characteristic of steppe ecosystems with low precipitation and forest ecosystems exposed to felling and fires.

The human-land system is a complex and open giant system composed of two subsystems of geographical environment and human activities. Though the optimization of the relationship between two subsystems, we could realize the regional sustainable development. The regional sustainable development is the embodiment of the most optimization of human-land system. This paper revealed human-land system, in terms of connotation, structure, relation, mechanism and function. Based on the theory of human-land system, the paper proposed the regional sustainable development assessment model and carried out the empirical analysis in the township scale. We chose Haiyong Town as the study area. The results show that the study area is in a good level of regional sustainable development, but in a primary stage. The economic sub-system and the society sub-system have reached the good level of sustainable development, but the environment subsystem is always at a low level. The study area should put forward optimization strategies within the economic, social and environmental subsystems, such as ecological agriculture strategy, circular economy strategy, modern service industry strategy, environmental protection system strategy and so on, in order to promoting regional sustainable development. The research results can provide scientific reference for the assessment of regional sustainable development and the formulation of regional sustainable development strategy.

Ecological problems of Zakamensk town are associated with sand deposits that were formed as a result of mining activities of former Dzhidinsky tungstenmolybdenum plant. Sands are accumulated in large quantities and they contain dangerous concentrations of heavy metals. Desertification in an urbanized area is manifested locally, but it differs from agricultural desertification by a profound and comprehensive destructive change in the components of the environment. Maps of soils, vegetation, types of lands, as well as ecological zoning maps of Zakamensk were created. The basis for the creation of electronic maps using GIS were stock, archive and own materials, topographic maps and remote sensing data. Urbanized desertification in Zakamensk is caused by chemical contamination of sandy eluvium, the spreading of pollutants by water flows and wind currents. Erosion occurs both in the form of flat flushing and linear erosion. The most intensive is gully erosion. Quantitative parameters of temporal variability of the erosive rainfall potential for the Zakamensk town are received. The quantitative characteristics of loads of pollutants on the territory of the town are determined on the basis of the erosion-deflation models. The calculations showed that 204 tons/ha of contaminated sand annually falls into the settlement area with water-erosion flows (Pb – 3.7 tons, W – 4.3 tons). Moreover, active wind activity led to the deposition of more metals (Pb – 5.6 tons, W – 6.5 tons) in the town.

Desertification is one of the most complex environmental problems in the Central Asian region. In addition to climatic factors affecting land degradation, in the border territories of Russia and Mongolia the intensification of desertification processes is influenced by human activities. A cartographic analysis of meteorological parameters, as well as vegetation state and dynamics spatial distribution based on the NDVI, was carried out. Dry zones occupy 65% of the area of Russia-Mongolia border territories. The prevailing climate zone is a semi-arid. The features of the dynamics of vegetation in the wet (1982-1999) and drought (2000-2015) periods are revealed. In the period from 1982 to 2015 a positive trend of NDVI is observed for 78% of the border areas and negative is for 22%. During the wet period the area of negative trends for both Russia and Mongolia amount 1.5% of the territory, primarily due to deforestation. The drought period is characterized by a nearly twentyfold increase in the areas of negative NDVI trends for the whole border territory. The analysis of the correlation of meteorological parameters and vegetation revealed that in drylands with negative NDVI trend, climate-induced desertification covers 63%, and anthropogenic 37% of the total area affected by desertification.

The identification of spatio-temporal patterns of transformation of the Selenga river channel is an important task, which has both theoretical and practical importance. Dynamic seasonal and long-term changes in the levels and flow rates of water in the Selenga river, as well as significant kinetic energy of the flow cause a high intensity of channel processes, which must be taken into account in the construction and operation of hydrotechnical and shore protection, as well as other protective structures. A retrospective comparative analysis of the dynamics of channel deformation based on the thematic automated interpretation of Landsat satellite multi-temporal data is carried out. This, together with engineering hydrological calculations, allowed us to perform a qualitative and quantitative assessment of the results of the long-term manifestation of natural processes in a vast area occupying part of the Selenga valley from the state border to its delta. In the course of work, for the first time a map of the Selenga river channel dynamics. Areas with different types of channel stability have been identified, the channel classification has been carried out into meandering, straight and braided sections.

Russia is the largest neighboring country of China. Between the two countries, the resources and industry are complemented, the political mutual trust is at a high level, and trade cooperation has a broad prospect. Choosing the best regions and the best industries to strengthen investment in Russia has a major strategic significance in promoting ‘the Belt and Road Initiative’ and China-Mongolia-Russia Economic Corridor Construction. However, the related researches are extremely limited. The investment environment is unclear, and the investment risk is unknown, which seriously restrict the investment in Russia and the trade cooperation with Russia. Our research team carried out scientific expedition, government visits and scientific research cooperation in Russia for several years, and obtained a great number of first-hand valuable data. According to the analysis on the data and Russian regional policies, this study constructed an investment environment evaluation model (ESI-PRA model), scientific assessed the investment environment for 83 subjects of federation in Russia, in terms of economic, social, infrastructure, policy, resource and accessibility, classified 4 types of investment regions, chose 3 investment priority regions, revealed the investment priority industries, demonstrated the main investment risks, and proposed the strategic policies. The research results provide direct scientific and technological support for strategic decisions, such as investment in Russia, bilateral economic and trade cooperation, and overseas layout of Chinese-funded enterprises. Moreover, it has an important practical and strategic significance for improving overseas geo-strategic interests of China and ensuring the construction of China-Mongolia-Russia Economic Corridor.

We investigated the landscapes and vegetation cover of the Ubur-Dzokoi hollow of the Selenga middle mountains. It was found that according to the physical-geographical zoning, the study area is a hummocky terrain of dry steppe landscape. The geosystems of the hollow include steppe and forest-steppe communities. Barchan relief formation is due to human activities and the dynamics of the wind regime. An analysis of key morphometric parameters of hollow relief is carried out based on the SRTM digital elevation model. As a result of the automated classification of Landsat TM multispectral images with a further identification of landscape types, multitemporal (for the years 1990, 2000 and 2010) landscape maps are created. These maps are validated by field landscape and geo-botanical investigations. The algorithm of the ISODATA unsupervised classification method was used, which allows the outlines with non-contrast structure of spectral brightness to be identified. The maps show clear changes in vegetation cover, indicating a decrease in the forest area, a gradual replacement of sedge-forb steppe communities with free-standing trees as well as an increase of sand deposits on unused arable and fallow lands. The spatial structure of vegetation on aeolian landforms was studied. It was concluded that their main component is psammophyte vegetation. We have made 25 geobotanical descriptions. The floristic composition of the coenocomplex includes 52 species of higher vascular plants. The ecological structure of the florocoenocomplex was identified on the basis of analyzing groups of plants in relation to the factor of soil moisture content. The method of ordination was used to determine the ecological differentiation of vegetation. To identify the spatial and structural organization of vegetation used geobotanical profiles and geobotanical descriptions of the sites, and satellite imagery. A large-scale (1:10 000) vegetation map for aeolian landforms was compiled. A correlation of the species in environmental groups showed a predominance of xerophytes (48%).

This paper presents an analysis of NDVI distributions and linear trends in the basin of Lake Baikal. Data of a thematic product MOD13Q1 of a MODIS spectroradiometer from 2000 to 2017 are used. Regression analysis is applied for more than 10 million time series. The slope coefficients and their statistical significance are calculated. Trends in surface air temperature and precipitation over the same period are also examined. It is revealed that the histogram of the number of pixels according to NDVI has a two-modal form, the maxima of which correspond to steppe and forest vegetation. 75.18% of the basin area has positive NDVI trends and 24.82%, negative ones. The negative NDVI trends are observed for steppe ecosystems of the Russian part of the basin, and for the steppes of Mongolia and forest ecosystems the trends are positive. For forest vegetation, the greatest and smallest values of trends are observed as a result of deforestation and forest restoration. The precipitation trends are positive in Mongolia and negative in Russia, which is consistent with the NDVI trends for steppes. Non-significant positive temperature trends are observed in the entire territory of the Lake Baikal basin. The seasonal dynamics of NDVI is highly correlated with air temperature and less correlated with precipitation. Preliminary data on the relationship between the width of tree rings and the forest NDVI have been obtained.

Under the conditions of climate change and intensive anthropogenic impact, the cenotic diversity of steppe ecosystems is changing. This paper presents results of a study of steppe communities in the arid climatic zone of Mongolia, in particular, a key site named "Mandalgovi". A classification of the vegetation in this territory is carried out using a cluster analysis of the coenoflora. We have identified 2 groups of formations of desert steppes including 5 formations and 12 associations by using a dominant-determinant approach. A relationship of the plant communities with the relief, general moistening, soil fertility, and salinity has been revealed using methods of ecological ordination. A spatial-temporal distribution of NDVI obtained with Landsat data and VEGA-PRO satellite service is analyzed. An increase in the areas with low values of the NDVI index (from 0.0 to 0.1) characteristic of desert steppes is revealed. This is due to a decrease in the phytocenotic diversity, substitution of indigenous species, and introduction of invasive species, thus leading to a drastic transformation of the plant communities.

Low-water period in the basin of Lake Baikal began in the middle 90s of the 20 century. A statistically significant trend in temperature increase and decrease in precipitation is established. The analysis of water inflow in Lake Baikal is performed. It is established that the Baikal level practically directly depends on the water content of the Selenga river. Dendrochronological reconstruction of the Selenga river run-off was carried out. In recent decades, a statistically significant trend towards the descent of the river run-off with the analysis of air temperature and atmospheric precipitation in the whole basin in the Russian part of the basin has been identified. The meridional transect (E 105-107, N 51-44) is chosen for the investigation, covering all arid climatic zones. A set of methods for remote sensing, geoinformation technologies and in-situ surveys of geosystems with the implementation of landscape, geobotanical and soil studies, mapping of vegetation of model polygons and key sites were used. A spatio-temporal assessment of the state of natural-anthropogenic geosystemsis carried out, criteria, indicators and tendencies of their dynamics are determined in connection with the processes of land degradation and desertification.

A 15-year-old low-water period in the basin of Lake Baikal established an endurance record in the entire history of observations. It began in the mid 90s of the last century. With some probability it may continue in the following years. An analysis of meteorological series of air temperature and precipitation in the region is conducted. A statistically significant trend of increasing temperature and decreasing rainfall is revealed. Atmospheric precipitation affects the long-term fluctuations in the river run-off to a greater extent than the other elements of the water balance. An analysis of the inflow of water into Lake Baikal is performed. It is found that the water level of the lake almost directly depends on the water content of the Selenga River. The minimal run-off in dry periods, as well as the annual run-off, tends to decrease. It is a continuous series of low run-off, which provided the negative trend in the minimal run-off. A dendrochronological reconstruction of the Selenga River run-off is made. A statistically significant trend of decreasing Selenga River run-off is revealed in the recent decades, and an analysis of temperature and precipitation for the basin on the Russian side is made.

Starting in the eighties of the 20th century, the scientists of the Baikal Institute of Nature Management (BINM SB RAS) have been conducting field observations of the Transbaikalia geosystems transformation due to the change of climate and nature management. An utmost importance is placed on the study of a negative response of the land geosystems. This is shown through their deterioration, degradation, and desertification in particular. Through the years of research (1985-2015) in dry areas of the north of Central Asia, the scientists of the BINM SB RAS established a network of key sites for contact monitoring of the status and dynamics of the geosystems and the negative natural-anthropogenic processes along the Baikal-Gobi meridional transect (51-44° N, 105-107° E). The monitoring of the status and dynamics of the vegetation cover of some key sites is conducted by processing and analysis of multitemporal and multispectral Landsat and MODIS Terra imagery. An automatic analysis of the time variation of NDVI and a comparison with the progress of the index in the previous seasons are performed. The landscape indication of the key sites is made on the basis of satellite imagery and complete geobotanical descriptions. Landscape profiles and facies maps with natural boundaries are created.

Model polygons located in arid and semiarid climactic zones in Central Mongolia were considered for the investigation of vegetation dynamics. For these polygons, plots of the NDVI temporal variation and NDVI maps of its multi-temporal values on the basis of Landsat TM imagery were constructed. The full-scale landscape indication of the selected NDVI areas was conducted. This indication is supported by the analysis of vegetation by environmental groups for drought resistance. The vegetation digression during this period is traced across almost the entire territory of the selected polygons.

The Baikal lake region is studied by the remote sensing methods, using fractal approach. It is shown that the using of fractal dimensionalities give possibility to describe the natural communities by exact quantitative way and make the classification of earth covers. There are classified three big classes with different values of fractal dimensionalities: smooth homogeneous areas, rough fragments with a small bushes, and forests.
