Abstract—The established functional relationship between soil losses due to deflation and the physical-geo-
graphic conditions in the wind corridors of the Ural–Caspian steppes has made it possible to identify agroeco-
logical types of lands with different intensities of soil formation and soil deflation losses, the ratio of which is
proposed as an index of soil resistance to deflation and desertization.

Keywords: Ural–Caspian subregion, wind corridor, deflation, tolerable soil losses, ecological criterion of soil
stability, mathematical simulation and projection of deflation processes
