Abstract

The article investigates the basic regular patterns reflecting the features and conditions of erosion processes treated as a consequence of human economic activities in river water catchment areas, the role in relief-formation and the influence on the state of natural-economic systems in the South Urals and Cis-Urals. One of the main factors predetermining the intensification of erosion processes is the transformation of slope runoff, including the increasing in its surface component and the destructive potential of water-flows under the deterioration of natural complexes in water catchment areas. It is shown that intensified development and trends for their growth are still observed in the regions (for example, in the Republics of Bashkortostan and Tatarstan) due to the increasing pasture load resulting from the growing livestock number in the private sector and due to the disappearance of economic incentives for avoiding cropland erosion, despite the overall decrease of anthropogenic impact. The article also provides analysis of the negative effect posed by the above-mentioned processes on the economic and environmental as well as the ecological conditions of minor river basins.
