Geosystems geoecological assessment of the basin of rivers for tourist valorization. Case study of Ilek river basin

Abstract

Nowadays in many regions of Kazakhstan a universal transformation of radical natural geosystems into geosystems natural and technogenic, especially used took place, i.e. directly or indirectly changed by economic activity of people, like e.g. industry, agriculture or development of tourism. In this regard geo-ecological researches are topical, especially for valorization and evaluation of tourism potential. This 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 let you establish quality of technogenic geosystem and to rank them from steadily functioning to the actively degrading.
