MODELING OF TRANSFORMATION PROCESSES OF NATURAL-MAN-MADE LANDSCAPES OF THE MIDDLE REGIONS OF THE SOUTHERN URALS

Abstract

The article examines the results of studies of landscapes formed by the activities of technical structures - quarries and overburden rocks, terricons, in which anthropogenic landscapes are formed - called technogenic. The authors presented the classification of technogenic landscapes of the Southern Urals depending on the forms of relief. Career and spoil-extractive landscapes were highlighted, in which multidirectional dynamics were observed. In turn, the quarry subtype is classified by the type of containing rocks into: dolomitic, sandy-clayey and dolomite-clayey, clayey complexes of ore deposits, sandstone. The processes of changing these complexes were modeled by compiling series of self-regulation and transformation of landscapes, which made it possible to track their dynamics and prediction of their state. As a result of the analysis, conclusions were made about the restoration processes in the South Ural natural and man-made landscapes. In almost all investigated technogenic complexes, a transformation of landscapes was observed - their modification from the original state. In particular, natural complexes at the site of extraction of ferrous metal ores and at dolomite complexes, the smallest - in sandy ones, are most affected by the most severe transformation.
