ASSESSMENT OF TRANSFORMATION OF NATURAL-TERRITORIAL COMPLEXES IN MINING TECHNOGENESIS

Abstract

Relevance. Structuring and formation of natural-territorial complexes take place over a long period of time. Over the entire period of transformation and establishment of stable territories, landscapes undergo significant changes. One of the factors of a similar transformation is the technogenic activity of the mining industry, in this relation, the authors evaluated the landscape transformation, studied the processes and schemes of landscape transformation under the influence of technogenesis as one of the main criteria that takes into account the location and expansion of these industries, which determines the relevance of this work. The aim of the research is to assess environmental stress and altered landscapes subjected to intensive anthropogenic load in the area of the copper-smelting plant activity. Objects: components of the landscape complex and soil cover in the area of intensive anthropogenic load, located in the vicinity of the city of Krasnouralsk, Sverdlovsk region. Methods: assessment of ecological tension of the territory; calculation of the coefficient of ecological protection of landscapes by the method of B.I. Kochurov; calculation of the arsenic radial differentiation coefficient in soil cover in the area of intensive anthropogenic load. Result. The analysis of separate components of landscape complexes is carried out. The characteristics of the processes of modification of territories subject to technogenic load are revealed. After calculating the coefficient of environmental stability using the method of B.I. Kochurov, it was revealed that the studied landscapes have an acute environmental situation and low stability. As proof of anthropogenic load arsenic concentrations in soils of the studied area was measured, that resulted in fixed excess of maximum permissible concentration in modified landscapes. The calculation of the coefficient of radial migration of arsenic in the soil explains the processes of technogenic load.
