ГЕОГРАФИЧЕСКИЕ ЗАКОНОМЕРНОСТИ СОВРЕМЕННОЙ ДЕФЛЯЦИИ В СТЕПЯХ ВОСТОЧНОЙ ЕВРОПЫ И ЗАПАДНОЙ СИБИРИ

Abstract

Modern relief of the steppe zone is subject to imposed process of natural and man-induced wind erosion. Chernozems and chestnut soils of the steppes are potentially prone to destruction by wind to a different degree which may be attributed to their genesis. While dust storms occur at about the same frequency, soils of European steppes are much more actively eroded, which may be explained by specific features of atmospheric circulation. Modern semiarid belt of the continental sector in Eurasia may be considered as an area of active wind erosion of the surface, with products of erosion being involved in global migration of matter.
