Abstract
Pasture loads are one of the key anthropogenic factors in the dynamics of the state of vegetation and soil cover of arid landscapes. The purpose of this study is to establish the spatial distribution of pasture loads in the Chyornye Zemli region using remote sensing data from space, geoinformation technologies, and statistical data. Mapping of livestock farms, sheepfolds, and other places of concentration of livestock for 1984–1986 and 2020 is carried out in this work. Both periods are characterized by a surge in desertification processes and a sharp increase in the areas of open sands and deflated lands. The areas of pastures with different loads during cattle grazing are established; patterns of spatial distribution of mobile sands depending on soil-forming rocks and distance from livestock farms are also determined. In recent years, compared with 1984–1986, the density of farms on sandy soils has increased, which has led to overgrazing, the destruction of vegetation, and the activation of Aeolian processes. Approximately 80% of pastures exceeded the permissible grazing standards, and 90% of pastures are located in a 3-km zone around the places of concentration of livestock. The results can be used to regulate pasture loads in the region to prevent the desertification of landscapes.
期刊介绍：
Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
