Periodization of anthropogenically determined evolution of steppe ecosystems

, : Periodization of anthropogenically determined evolution of steppe ecosystems. Ekologiya (Moscow) 0(5): 17-25

The evolution of the vegetation cover caused by anthropogenic factors was analyzed in northern Black Sea area. The dynamics of the intensity of humus formation, biogeochemical transformations, and soil erosion were presented. The main evolutionary phases that lasted 2600, 7500, 90-110 and 40 years were identified. These phases reflect the polyclimax nature of steppe ecosystems.
