- Аннотация: A detailed study of the soil cover of a sinkhole (300 m 2 ) in the dry steppe landscape of the Bog-dinsk–Baskunchak Natural Reserve in Astrakhan oblast has been performed, and the factors of its differen-tiation have been analyzed. The indices of pedodiversity have been calculated and compared for karst sink-holes in the dry steppe and northern taiga landscapes. Qu antitative parameters of the lateral migration of solid soil substances on the slopes of the sinkhole have been determined. The rate of soil erosion decreases from the slope of southern aspect to the slopes of western, northern, and eastern aspects. On the average, it is esti-mated at 0.4 mm/yr. The average rate of accumulation of solid substances on the lower parts of the slopes and in the bottom of the sinkhole reaches 0.74 mm/yr. A compar ative analysis of the soil properties attests to their dependence on the particular position of a given soil within the sinkhole. Downward the slopes of the sink-hole, full-profile brown arid soils (Cambic Calcisols) ar e replaced by sierozem-like soils (Haplic Calcisols), light-humus poorly developed soils (Luvisols), lithozems (Leptosols), and stratified soils (stratozems, or Col-luvic Regosols). The soils within the upper ring-shape soil microzone are more diverse and contrasting with respect to their morphological, physical, chemical, and physicochemical properties. The degree of soil con-trasts decreases down the slopes of the sinkhole towards its bottom. The studied sinkhole is characterized by considerable pedodiversity. Quantitative parameters of pedodiversity for the sinkhole in the dry steppe zone are higher than those form the sinkholes in the northern taiga zone.
