Assessment and spatial analysis of agricultural land erosion processes in the Samara region
Authors: Samokhvalova E V , Zudilin S N 
Published: November 2020

Abstract
Water and wind erosion of land causes annual damage since it leads to soil degradation and loss of fertility, reducing the economic indicators of agricultural production. Detailed systematization of land resources with an assessment of the scale and level of land degradation provides a basis for ranking areas by relevance and effectiveness of erosion protection. The article assesses the level of degradation of agricultural land in the Samara region by the scale of economic losses under the influence of water and wind erosion of soil with differentiation by administrative districts. The map of eroded lands has been developed. The results of integrated erosion zoning of the territory provide an information basis for identifying priority areas requiring anti-erosion measures, as well as for optimizing the structure of agricultural land use. The main directions of anti-erosion organization of the territory and on-farm land management, depending on the features of the landscape and the nature of damage, have been described.

Published: November 2020

Abstract
The article scientifically substantiates the formation of the ecological frame of the urban area in arid conditions. The object of research is the greening system of the city of Elista, the capital of the Republic of Kalmykia. The main methods of the study are analytical, cameral and comparative geographical methods. The study shows that the intensity of traffic, physical, geographical and meteorological conditions and the condition of streets affect the gas content of the city’s air basin. The zones of active pollution by emissions into the air are intersections and stops of public transport. The dust-collecting capacity of leaves of certain types of vegetation does not adequately ensure the sanitary and hygienic state of the city’s atmospheric air. Based on the principle of a systematic approach to the problem, ecological-functional zoning of urban landscapes, as the basis of the ecological framework, has been carried out. The structure and its main elements that can act as "cores" and "corridors" of the ecological framework are presented. The study found that open, unconverted spaces account for about 26% of the city’s area. The implementation of the principles of forming an ecological frame and the broader use of conifers for landscaping in Elista is aimed at solving an urgent problem, namely, improving the ecological situation in the city and providing a favourable, comfortable environment for the population in arid conditions.

Published: November 2020

Abstract
Environmental changes under the influence of anthropogenic factors are shown. Ecosystems accumulate toxic substances. A list of plants accumulating heavy metals is given. Using plants as indicators of toxicity, contaminated sites are determined and methods for restoring soil fertility are applied. The doses of introducing zeolite-containing clays together with phytoindicators are justified. The greatest sorption capacity was shown by the ragweed plant. As sorbents for restoring the environment and improving soil fertility, plant wastes, such as corn cobs, sunflower heads, are used. The studies were conducted in various soils of the North Caucasus. Measures to reduce the toxic load on the ecosystem were theoretically and practically justified. The maximum amount of toxic substances accumulates in ragweed. Indicator plants can be widely used in the rehabilitation of soils contaminated with heavy metals and other chemicals.

Authors: Gorovoy V O , Kolosov A D , Kondrat’ev V V , Doshlov O I 
Published: November 2020

Abstract
The spectral characteristics of coal and oil pitch are compared among themselves. An insignificant contribution of aliphatic functional groups to the total spectrum intensity for coal pitch is noted. Analysis of the obtained 13C NMR spectra showed qualitative structural features of the pitch components, such as the absence of signals in the range of 150-200 ppm, which indicates the absence of carbonyl- and carboxyl-containing fragments in the components of the pitch components. The content of radiocarbon in the samples of oil pitch and carbon nanoparticles was measured.

Published: November 2020

Abstract
The analysis of the influence of new technical solutions in the technologies of electrolytic production of aluminum on the quantitative indicators of pollutants in the emissions of anode gases is presented. Describes methods to reduce emissions of resinous substances, including 3,4-benz (a) pyrene. The problem of emission capture during cooling of the pins extracted from the anode is considered in detail. For the first time in the Russian Federation, it was proposed to use environmentally friendly oil pitch, in which 3,4-benz (a) pyrene is practically absent. A variant of collecting tar contaminants by cooling anode pins in an aspirated cartridge is proposed. The new solution reduces tar emissions by an average of 5%.

Published: November 2020

Abstract
The authors created a cellular automata model simulating the dynamics of a fire source for rough terrain on a triangular grid, including cases of artificial and natural obstacles. The model can be used as a part of a complex of models describing fire propagation and migration of polluting aerosol and gaseous products of combustion in the atmosphere. It is applicable for predicting a possibility of occurrence, intensity, scenario of fire propagation, as well as assessing its impact on environment and also in decision support systems for the prevention of emergency fire situations. For the model description of real settlement areas, we used a digital model of the territory of the Krasnodar Territory built using geographic information systems.

Published: November 2020

Abstract
With extremely low forest cover in the Orenburg region (4.6 %), where the environmental stress factor is particularly acute, forests have exceptional climate control, soil protection, and sanitary and hygiene. The priority area of practice and science is the preservation and growth of the forests of the region, which serves as a kind of framework in stabilizing the environmental situation in the region. The presented work shows the state of forest stands under conditions of anthropogenic impact. The culmination of the current radial growth has been established and the so-called “surge” of the current growth of tree stands has been detected with the accumulation of threshold levels of toxicants in a polluted environment, which subsequently leads to loss of stability and destruction of plantations.

Authors: Shirokorad I I , Pafnutova E G , Fadeeva O M , Oleksenko O M 
Published: November 2020

Abstract
The paper is devoted to the study of the efficiency of the agricultural land use by agrarian universities. The need to consider this topic lies in the fact that agrarian universities, which train personnel for agricultural industries, face a number of problems in ensuring and developing the agricultural production on the basis of their capacity, including land being the main means of production. However, the universities do not have sufficient funds. Their resources are always limited, so, on the one hand, rational savings will allow maintaining the quality of education, but on the other – the absence of supporting measures reduces the possibilities of meeting modern requirements of education. The theoretical significance of the study is to summarize the data on the area of agricultural land and to study the specifics of their functional purpose. During the work, the analysis of the efficiency of agricultural land use was carried out, the indicators of which can be used as a basic element for increasing economic and entrepreneurial activity of universities. Hence, the study proposes a model of planning the maximum (minimum) value of assessing the level of agricultural land use by agrarian universities to ensure proper economic activities, as well as educational, practical and research works. The results of the study can be taken into account in the preparation of promising plans for the development of agrarian education.

Published: November 2020

Abstract
The paper considers the problem of processing information arrays of geographic information systems based on intelligent technologies. The authors note that geoinformatics is not only an area of scientific research, but also a technology for collecting, storing, transforming, displaying and distributing spatially coordinated information, the purpose of which is to solve the problems of inventory, optimization and management of geosystems. Geoinformatics as a field of production includes the production of software and hardware, the creation of databases and control systems. Moreover, the interrelation of cartography and geoinformatics is indicated, which is manifested in the following aspects: thematic and cartographic maps - the main source of spatio-temporal information; the systems of geographical and rectangular coordinates - the basis for the coordinate reference of all information received and stored in the GIS; maps - the main means of geographical interpretation and organization of remote sensing data and other information used in GIS (statistical, analytical, etc.); cartographic analysis - one of the most effective ways to identify geographical patterns, relationships, dependencies in the formation of knowledge bases included in GIS; mathematical-cartographic and computer-cartographic modeling - the main means of converting information in the decision-making process, management of expert reviews, making forecasts of the development of geosystems; a cartographic image - an appropriate form of presenting information to consumers. In order to solve managerial tasks, it is proposed to implement cognitive graphics in geoinformation systems based on artificial intelligence, which accompanies the process of problem solution and decision making on choosing a route based on criteria.

Authors: Nizovtsev V A , Erman N M 
Published: November 2020

Abstract
This paper presents a comprehensive landscape and historical study of the historical and cultural monument "The tract of St. Mary’s Mountain". The territory of this monument, located at the crossroads of the main medieval overland roads, is ridden with numerous archaeological sites: ancient settlements, mounds and burial mounds, dating back to the 1st millennium AD, as well as natural monuments. Complex field expeditionary and office landscape-historical studies were carried out, as a result of which the modern landscape structure of the monument was analyzed, and the natural properties of the natural and cultural-historic landscapes of this territory were determined. A large-scale map of conditionally restored landscapes was compiled, and an assessment of the resource base, landscape and environmental conditions of the settlers’ life was completed. A comprehensive spatial and terrain analysis of the archaeological and historical monuments was completed, and retro-reconstructions of the landscape-economic systems of the ancient Russian period were created. As a result of the research conducted, it was established that the settlement systems and environmental management systems were clearly determined by the local landscape structure. The comprehensive studies conducted have made it possible to conclude that the historical and cultural landscape of "The tract of St. Mary’s Mountain" possesses a unique combination of natural and historical objects and is considered a model archeological monument of Ancient Russia, which historians compare with the synchronous monuments of Western and Central Europe of the "take off to the hills" era (11th–12th centuries).
