GEOINFORMATION ANALYSIS OF ECOLOGICAL STABILITY OF A RIVER BASIN OF TASHLA

Abstract

Problems of pollution of the small rivers of Stavropol Plateau are considered. On the example of river of Tashla the main sources of pollution are analyzed. On the basis of geoinformation modeling the main characteristics of a river basin are analyzed, specific features of the pool as natural and territorial complex are marked out. The analysis of an ecological condition of the basin of the river of Tashla on the basis of determination of coefficient of ecological stability of a landscape is carried out. On the basis of the given remote sensing of Earth and cartographic materials the karto-schemes reflecting the main characteristics of the basin of the river of Tashla are built. On the basis of the analysis of the constructed schematic map the unstable systems occupying the big spaces of a reservoir in the top and average parts of river system interfering stabilization of an ecological condition of the river are defined. The measures for optimization of an ecological condition of river system consisting in creation of the individual program of rehabilitation of the small rivers and carrying out public monitoring of river basins are offered.
