L. Yu. Ditz, N. V. Shemetova
Abstract
The paper deals with the problems of anthropogenic desertification in the southern regions of the Novosibirsk District. The joint effect of climatic factors (an increase in aridity) along with anthropogenic ones (ploughing up, pasture digression, etc.) is described, these factors being the reasons of ecological crisis of arid areas. Anthropogenic load on ecosystems caused activation of deflation processes both in ploughed soil and in natural forage acreages, expansion of the area of soil salinity, and a decrease in the biological variety of growth.
