Problems of Integrated Assessment of Geo-ecosystems of Steppe Zone of Ural River Basin

Methodological approaches to the assessment of natural geo-ecological systems are researched. Analysis of the interaction of natural and anthropogenic components of the geo-ecological systems and their management is based on the consideration of natural-resource potential in the changing spatial and temporal connection. The principles of identifying and mapping of geo-ecological systems of various rank. Structural changes resulting from anthropogenic transformation allow establish the quality of geo-ecosystems and rank according to the degree of self-realization and sustainability.
