Authors: Krasulina O Y , Rossokhin V V , Bobodzhanova L K , Safonova A S 
Published: January 2021

Abstract
The Arctic sea ice is an essential element of the Earth’s climate system. It regulates the regional balance of heat and fresh water, the subsequent circulation of the atmosphere and the ocean in the Arctic zone as well as in lower latitudes. The given article demonstrates how socio-economic factors affect the volume of the Arctic sea ice. It also provides the detailed analysis: the climate change assessment in the Arctic zone is presented and the role of various factors intensifying climate changes in the Arctic zone are considered. With the economic growth of the country, the consumption of the population increases and this fact affects the environment; as a result, industrial growth contributes to the increasing of the emissions of pollutants and greenhouse gases. Climate change is not a fiction and it is obvious that anthropogenic emissions have increased. The authors of the article associate the ecosystems of the Arctic zone with economic systems. The measures aimed at the development of the economy and the environment of the region are proposed. Applying new technologies Industry 4.0 will allow the economy to grow exponentially.

Published: January 2021

Abstract
This article presents the method for modelling underwater three-dimensional topography and it’s combining with terrain under conditions of incomplete source data. The technique for constructing 3D elevation model was tested within the research projects conducted in Matrosov Institute for System Dynamics and Control Theory Siberian Branch of the Russian Academy of Sciences in collaboration with colleagues from other research institutes of Irkutsk Scientific Center under the comprehensive studies of Lake Baikal, the Angara River and the Bratsk Reservoir. We present an algorithm for combining underwater topography with terrain based on heterogeneous source data using the Delaunay triangulation. The combining yields a high-quality 3D elevation model. This model can be used to make forecasts of the changes in the coastlines of reservoirs, which are associated with water discharges from hydroelectric power stations. The described technique was used to solve some practical problems and showed its effectiveness. To combine the data on the terrain and underwater topography, we developed a special software using the Delaunay triangulation algorithms. For data layers, their roles were indicated during the triangulation. Layers contained the information about terrain, watermarks, contours of the coastline, and underwater topography. For underwater topography, we used the information about the marks of the water edge. Based on these data, we built an additional triangulation, from which we subsequently obtained the information about heights because contours of coastlines are confined to heights, and depths are measured relative to heights. As a result of this study, we processed some settlements and estimated possible flooding.
Transformation and ecological stability of soils of phosphoritic landscape-geochemical systems of depression of Lake Khuvsgul of the Baikal rift zone
Authors: Martynova N A 
Published: January 2021

Abstract
Sustainable development of the Baikal-Khuvsgul basin is not only of national, but also of great international importance. This status gives priority to preserving biodiversity and the natural-historical biosphere in general, and to the development of strategies for the rational utilization of natural resources and sustainable development of territories within the basin of the unique ecosystems of Lakes Baikal (Russia) and Khuvsgul (Mongolia). We carried out a comprehensive study of the morphogenetic and ecological features, ecological stability of soils and landscapes of the Khuvsgul phosphorite basin of the mountainous Khuvsgul region of the southwestern branch of the Baikal rift zone (BRZ). This analysis upgraded the existing knowledge of possible trends in the transformational growth and ecological balance of the soil cover of this territory both under the conditions of the natural development of geosystems and under the destabilizing anthropogenic and technogenic impact. Possible negative side effects of the development of phosphorite deposits on the unique in natural and cultural terms ecosystems of Lake Khuvsgul were predicted.

Authors: Yanchuk M S , Vorobyova I B , Vlasova N V 
Published: January 2021

Abstract
During the winter period from 2015 to 2019, in the third decade of February and the first decade of March, snow and ice samples were taken from the area of the Goloustnoye municipal settlements located on the west coast of Lake Baikal, as well as from the adjacent water area of the lake (at a distance not exceeding 1000 m from the coast) and the Goloustnaya River. The sampling was carried out to give a modern ecological assessment of the state of the considered natural components and determine the relationship between the presence of pollutants and the level of human impact. Based on the data obtained, we constructed a map of the distribution of suspended solids, sulfates and heavy metals, such as manganese, copper, zinc, and lead, in the study area. The highest content of pollutants was determined in the samples of snow taken near settlements: the village of Bolshoye Goloustnoye and the village of Maloye Goloustnoye. Additionally, increased concentrations of suspended solids, sulfates, nitrites, ammonium, and manganese were found in the coastal area of Lake Baikal. At the same sampling sites, the pH values of meltwater corresponded to alkaline waters, which indicates anthropogenic pollution.

Authors: Tsygankova M V 
Published: January 2021

Abstract
The article deals the landscape structure of the Iya river basin (left tributary of the Oka river). Landscape analysis was conducted in order to identify landscape-hydrological conditions of flood formation in 2019. Since the available small-scale landscape maps for the study area did not meet the requirement of the scientific issue in detail, a landscape map was compiled at a scale of 1: 500 000. The territory is heterogeneous in its physical and geographical conditions and topographic and humidification features, which resulted in formation of different landscapes and different types of intralandscape differentiation. We used a standard set of data to create the landscape map of the Iya river basin at a scale of 1: 500 000: electronic multi-scale topographic maps, Landsat 7 and 8 satellite images, digital terrain model, slope steepness and exposure maps, small-scale landscape, geobotanical and soil maps. We based on the landscape classification, which was developed for the map “Landscapes of the South of Eastern Siberia”. The landscape diversity of the basin is represented by 39 groups of facies, united in 17 geoms and 4 classes of geoms. The landscapes of the mountainous, foothill-plain and upland-plain parts of the Iya River basin are substantially different in their appearance, characteristics of individual components, and their nature. The area of landscape units increases from southwest to northeast as the absolute height and vertical dissection of the relief decrease, their diversity increases towards the foothill part of the Iya river basin.
Significance of the China-Mongolia-Russia economic corridor for the Irkutsk Region and Mongolia
Authors: Fartyshev A N , Davaanyam S 
Published: January 2021

Abstract
The paper considers the issue of implementing the Silk Road Economic Belt and especially the China-Mongolia-Russia transport corridor and its influence on the development of the Irkutsk Region and Mongolia as intracontinental peripheries. According to customs statistics, the Irkutsk Region mostly exports aluminum to the well-developed countries of the West and mineral fuel, timber, and cellulose to the East (China, Japan, and South Korea), and after increasing the throughput of railways, it will strengthen its export-resource dependence subject to the current trends. Mongolia has the same problems because the Mongolian economy has limited diversification and is strongly dependent on the extracting industry. Routes of the China-Mongolia-Russia economic belt fit the objects of the promising project “New Angarstroy” that makes the Irkutsk Region a full-fledged member of this concept. The convergence of the commodity markets of Siberia and Mongolia resulted from the shortened economic distance makes it possible to develop efficient end-use production facilities up to the creation of cross-border Russian-Mongolian territorial production complexes. On the other hand, distances are not so critical circumstances for building an innovative economy. However, the main problems of regional development within the framework of the initiative lie in the institutional and political field, i.e. the mechanisms of financing suggested in the concept of the Silk Road Economic Belt are not efficiently used in the territories of Siberia and Mongolia.
The Baikal region: economic specialization
Authors: Ippolitova N A , Rogovskaya N V 
Published: January 2021

Abstract
The article presents the economic specialization of the Baikal region, which includes three constituent entities of the Russian Federation: Irkutsk oblast, the Republic of Buryatia and Zabaikalskii krai, which are united by the basin of Lake Baikal-a world natural heritage site. The problem of examining economic specialization is currently very relevant, which is explained by the need to increase the level of socio-economic development of the country and its individual territories, the efficiency of production and regional specialization. We analyzed the economic complex of the Baikal region, revealed its determining factors and the branches of industrial and agricultural specialization. Peculiarities of economic and geographical location, natural resource potential and natural and climatic conditions define the development of the economic complex of the Baikal region. All these factors determined the economy orientation to the development of extractive industries and industries related to their service. In recent years, this trend is reinforced. Agriculture in the Baikal region develops in extreme natural conditions: reduced biological activity, a significant part of which is characterized by low indicators of efficiency and production intensity. Agriculture in the Baikal region includes two main industries-animal husbandry and crop production, their shares in the gross agricultural output of Irkutsk oblast are approximately equal; but in Zabaikalskii krai and the Republic of Buryatia, the leading agricultural industry is animal husbandry and its share is over 70%. The cultivation of grain and vegetable crops also plays a significant role in creating a local food facility.

Abstract
The Baikal Natural Territory includes Lake Baikal, its water protection zone, the basin within the territory of the Russian Federation, adjacent specially protected natural areas, and also the territory adjacent to the lake up to 200 kilometers wide to the west and northwest of it. The development of decisions to solve environmental problems of Baikal Natural Territory should be based on a comprehensive analysis of the monitoring data. The monitoring data and analysis methods are distributed among participants (organizations and departments). But data and analysis methods exchange is very low. An approach is proposed for the introduction of digitalization in the environmental monitoring of the Baikal natural territory, based on the integrated implementation of cyber-physical systems, the digital method of data transmission, as well as the use of digital ecosystems and platforms using the service-oriented paradigm, OGC standards, end-to-end and WEB technologies, cloud and distributed computing, large amounts of spatio-temporal data. Based on service-oriented paradigm digital resources and processing services implementing REST or WPS standard should be created by the monitoring participants. Requirements for digital resources have been defined. Infrastructure components have been developed to simplify development of digital resources, processing services and to organize interaction among participants.

Published: January 2021

Abstract
Because of its accuracy, Convolutional Neural Network (CNN) has become an important method in the field of fault diagnosis. However, the traditional CNN has a long time of training and diagnosis due to its complex structure. At the same time, due to many problems in the network, the detection accuracy is not high. Therefore, this paper proposes an improved CNN for fan bearing fault diagnosis, which speeds up the feature extraction of the network by improving the network structure; solves the problem of part of neurons not being activated by improving the activation function, and improves the accuracy of network detection. Finally, the network proposed in this paper is validated on the data set and compared with other advanced fault diagnosis algorithms. The results show that the accuracy of the algorithm proposed in this paper can reach 99.76%. Because of other algorithms, and the training and diagnosis time is relatively short, it has practical application value.t).

Authors: Zhang Jiaqi , Zhang Tao 
Published: January 2021

Abstract
With the rapid development of renewable energy, there is a shortage of renewable energy consumption, resulting in serious waste of resources. Relying solely on technological improvement can no longer meet the large-scale consumption demand of renewable energy, and market-based measures are needed to further promote the consumption of renewable energy. Nowadays, China has established multiple market mechanisms. In order to measure the market mechanism's contribution to the renewable energy consumption effectively and guide the adjustment of the market mechanism, a comprehensive evaluation system needs to be constructed. Therefore, this paper first determines each evaluation index of the evaluation system from the three aspects of power generation side, power grid side and social side, and then proposes the concept of influence degree, which is used to form the evaluation index value. Then the evaluation is established based on the improved entropy method and ideal solution. Finally, taking the measures of developing auxiliary power service market in Fujian Province and other regions as an example to evaluate its impact on the renewable energy consumption, which proves that the method used in this paper has application value in evaluating the effect of the operation mechanism of the power market.
