Criteria of Assessing the Current State of the Kuban River Geosystem

Abstract

Abstract In the current state, delta geosystems should be considered from the standpoint of “sustainable” development. Therefore, the assessment of the current state of a natural object consists of analyzing changes in its basic properties and taking into account its features (the presence of zonal and azonal elements) that occur under the influence of anthropogenic human activity. Such an analysis should include the following types of criteria: criterion showing the nature of the “openness” of the geosystem (environmental factors); criterion reflecting the dynamics of changes in the supply and outflow of water into the geosystem; criterion describing the water exchange and ion exchange of coastal estuaries with the sea, and hydrochemical regime; criterion characterizing the ecological state of the geosystem (biomass stock). The results indicate that fundamental properties of the geosystem are characterized by the openness of the geosystem and azonal elements. When passing the analysis and expert assessment of the current state of the natural environment in the economic use of this territory, it is necessary to pay special attention to changes in the degree of openness (river flow), changes in the structure of the geosystem (landsliding and agricultural development of land).
