Geoinformation methods of geoecological features of the territory study

Abstract

The paper considers the analysis of dynamics changes in the Ilmenno-Bugrovy lowland of the Caspian region to evaluate the accuracy of detecting changes in the geoecological peculiarities of the region. The method of remote sensing is used for a more detailed study of the Ilmenno-Bugrovy lowland region. A complex of various methods of fixing the natural situation using photographic, scanner, and other special equipment is used. The authors also apply visual observations and methods for calculating quantitative indicators in landscape ecology. The unique landscape of these regions is represented by the tracts of the Baer knolls and inter-mound plains, which are occupied by lake-like reservoirs, ilmens, of varying degrees of salinity which have preserved the water surface due to their connection with the arms of the Volga River. The natural water regime of these regions is disturbed, and in the process of extensive environment, the Baer knolls are destroyed, natural territories are polluted as a result of the Volga river flow regulation. The information was collected on the geoecological state of the site in this landscape region using modern geoinformation research methods. These methods made it possible to identify the features of anthropogenic influence in these regions, to develop a set of measures to prevent the environmental deterioration and preserve the biological diversity of these regions. The analysis of the obtained results made it possible to identify an unstable ecological situation in these unique natural territories. The structure and texture of the landscapes of the Ilmenno-Bugrovy lowland is changing under the conditions of active anthropogenic and technogenic impact.
