GEOCHEMICAL MONITORING OF INDUSTRIAL CENTER FOR DEVELOPMENT OF RECREATIONAL AREAS (ON THE EXAMPLE OF KHROMTAU-DON INDUSTRIAL HUB, KAZAKHSTAN)

Abstract

Landscape-geochemical assessment of the industrial areas is of particular interest. This paper describes the microelement composition of soils, investigates hydrochemical composition of surface waters and vegetation of the territory. A landscape-geochemical analysis of the Khromtau industrial zone was carried out. The article includes results of studying of the patterns of the profile distribution of the morphological, physico-chemical properties of soils and their transformation under the influence of the mining industry and urban loads. The study reveals main types of rearrangements of the ecological and geochemical structure of soil profiles, which sharply differ from the background soils of the region. During field research, keyareas were laid. In the key areas, soil pits were laid for sampling soil from various horizons, for subsequent chemical analysis of the constituent components, and vegetation was selected for chemical analysis. Geoenvironmental analysis allows scientific justifying creation of technogenic reservations as a basis for protection of recreational areas. The work contains conceptual and methodological approaches to ensuring geo-ecological assessment of geosystems. The analysis of the interaction of the natural, economic, social subsystems and control systems with modern geosystems, based on the ecosystem services, provided by natural subsystem demanded by society and economy. A model of technogenic geosystem and a series of the indicators reflecting properties, quantitative and qualitative features of each block of subsystems has been developed. Structural variations which arise in geosystem as a result of anthropogenous transformation lets to establish quality of technogenic geosystem and to rank them from steadily functioning to the actively degrading.
