Based on long-term data from expeditions and permanent stations, a study is made of the spatio-temporal regularities inherent in the changes in the structure and quantitative characteristics of the mesopopulation in soils of southern-taiga landscape as a result of the anthropogenic impact. Consideration is being given to the ability of zoocenoses to retain their invariant properties (regenerational stability) after exogenous disturbances in different landscape-ecological situations. The state and recover rate of soil-biotic communities are estimated depending on the dynamical category of a facies, and on the intensity of anthropogenic impact. Local destabilization factors are revealed for successional processes in the southern-taiga geosystems.
