It is shown that since the beginning of field development, a single natural and historical process of oil and gas generation and accumulation has been accompanied by the transformation of the entire complex of geological, biochemical, geochemical, thermobaric and hydrogeological environmental conditions and modern landscape genesis. Studying this process within the territory of leading oil and gas

Results of a long-term comprehensive study of the natural environment of Northeastern Cisbaikalia are presented. Some theoretical and practical issues of a cartographic study of topological-level geosystems are considered in terms of Academician V.B. Sochava’s theory of geosystems. We compiled the map of geosystems of the North-Baikal and Upper-Angara depressions displaying the ecological-dynamical

Maximum permissible concentrations for chemical elements in soils (MPCs) of Russia, Germany, Canada, the Netherlands and the USA are compared. In Russia, general sanitary, water-transferred and translocation MPCs are created; in Germany, general sanitary and translocation, and in the Netherlands, the USA and Canada, general sanitary. It is found that the Russian MPCs for total contents of chemical

The state and the prospects of implementation of major investment projects combined into the Eastern Gas Program have been analyzed. The terms of realization, the state of resources and the state of gas transportation system under the projects forming part of them are considered. It is shown that only one (Sakhalin) of four gas production centers foreseen in the program has an adequate infrastructure;

We calculated the water balance and investigated the mineralization of water in closed Lake Chany. the largest lake in Western Siberia in terms of its water area and of great ecological and fisheries importance. The most important natural characteristic of the lake is the cyclic fluctuation of the water level caused by the variability in the overall humidity of the Ob-Irtysh interfluve. The water level

We examine the geographical features in the distribution and the radiation parameters of radioactive rock dumps in the Elkon uranium ore area on the territory of South Yakutia. It is pointed out that the dumps under study are geomorphologically located on the Elkon horst which is a protrusion of crystalline basement rocks, towering over the territory of the Aldan highlands. It is found that most of

Socio-economic maps are essential for identifcation and system analysis of sectoral and territorial imbalances, ensuring the effective organization of productive forces, planning and forecasting of socioeconomic development of the territory. This paper presents the authors’ experience in creating and interpreting socio-economic maps in national and regional atlases, analyzes current trends in the development

The spatial distribution of total water vapor content over the Yamal Peninsula and adjacent territories was analyzed using data of four-year-long measurements from the European Envisat satellite during warm periods of the year (June-August). Special attention was given to water vapor variations at the transition from little to abundant water-bearing areas of the underlying surface. It was found that

We examine the landscape structural features of the Mukhtel lowland and the mountains surrounding it on the southwestern coast of the Sea of Okhotsk. An analysis is made of the main formation factors for modern landscapes and for the structure of vegetation as the main indicator of its spatial organization. The influence of the landscape inversion is determined, which manifests itself in the formation

Presented are the results from investigating the atmospheric self-purification capacity over the cities of Irkutsk, Beijing and Ulaanbaatar for the summer and winter seasons of 2017–2018. The meteorological potential of the atmosphere (MPA) was used as the criterion for assessing the atmospheric self-purification. It is shown that in the summer season of 2017 the favorable meteorological conditions

We substantiate the use of the previously developed methods to classify sections of the largest river (Lena) from the types of channel processes and special aspects of their management, i. e. water resource use, exploitation of the river as the water transport way, development of riverine areas and construction of river crossings for service lines. For assessing the complexity of river channel reconfguration

The economic significance of the historical and cultural potential, including the field-established geographical centers of the regions, is revealed. The advantages and disadvantages of the methods of determining the geographical centers of territories are considered. Their relationship with geionformation systems is determined. It was found that the software of these systems has the functionality

We examine the fundamental tenets of the theory of geochemical barriers and their role in landscapes associated with an intensification of migration processes caused by an enhancement in anthropogenic activity, including in the sphere of industrial production. Observational evidence indicates that the flow of multiple elements in the form of substances, which is produced by the aluminum smelters of

We examine the current problems of Lake Baikal level regulation. A comparative analysis is made of the changes in the lake level, the range of its fluctuations and in the intra-annual amplitude for the 120-year-long period of observations in natural and regulated conditions. The period 2014–2017 with an extremely low water level is analyzed. It is pointed out that the inconsistency between existing

A specific feature of the term “transboundary” is defined, which is usually perceived as an opportunity to overcome the borders separating the territory, and is used as opposed to the “frontier” objects adjacent to the border but not crossing it. Transboundary interstate territories are discussed, where only regulated activities may be carried out, such as nature conservation in solving the problem

This paper presents results of wildfire studies conducted Transbaikalia over the last five decades. Station-based experimental investigations into fire hazards of vegetation accomplished at the regional forest fire stations during those years covered all altitudinal vegetation zones, representative landscape localities and forest types. Route investigations were made in different natural areas. Arial

An analysis is made of the investments in fixed capital at the regional and municipal level in Irkutsk oblast, the Republic of Buryatia and Zabaikalskii krai. On the basis of the average indicators considered, the conclusion is drawn about the general lag of the Baikal region from Siberia and Russia over the course of the last several decades. Population changes in municipal districts and urban districts

We examine the composition of metals in the waters of the southern tributaries of Lake Baikal as well as comparing it with the composition of metals in bottom sediments and calculating the water migration coefficients of metals. The territory of the southern part of the lake drainage basin was regionalized according to the ability to ensure a particular water composition. The contribution from the

A brief geographical description is provided for Lake Khanka and its drainage basin where the Russian part accounts for more than 90% of the area. Sixteen rivers on the Russian territory and eight rivers on the Chinese territory flow into the lake. Only one river, Sungacha, flows out of the lake; it is a border river and connects Lake Khanka with the Ussuri river. A historical analysis of the water

The paper gives characteristics of natural and anthropogenic factors responsible for the geoecological situation inside the boundaries of the floodplain-terrace complex of the Tuul river within Ulaanbaatar. Among them, the geological structure and orography (occurrence in the intermontane depression), the specific character of climate-forming (frequent temperature inversions) and hydrological (mainly
