Tabelinova A.S. Geological Zoning of Norteastern Caspian Region // Arid ecosystems. 2020. V. 26. № 3 (84). P. 50-58. | PDF

An analysis of the function of Northeastern Caspian region landscape structure in context of geological processes development is presented in the paper. The aim of investigation was the geoecological zoning based on studying the main factors defining specific direction and intensity of development in modern landscapes of the Northeastern Caspian Sea region: altitude-landscape and geomorphological differentiation of the territory generated during the long-term development of the region, significant fluctuations of Caspian Sea level and the evolution of anthropogenic activities including oil extraction. Spatial differentiation of geoecological processes into landscapes of Northeastern Caspian region was mapped based on studies of such processes at the different anthropogenic modifications of six key plots. Detection of spatial distribution of geoecological processes in the landscapes of studied region was based on direct and indirect interpretation indicators of Landsat 5 and Landsar 7 multiband synthesized satellite images. GIS-mapping made possible to prepare the map of geoecological regions of Northeastern Caspian region. 25 geoecological regions and 127 subregions were mapped according to spatial structures (subspecies of modern landscapes) and anthropogenic factors defining geographical distribution and domination of specific geoecological processes.

Key words: geoecological regions, geoecological processes, modern landscapes of the Northeastern Caspian region, Landscape levels.
