Analysis of soil stability on the basis of nonlinear dynamic models

摘要

Results of a study of soil stability are presented on the basis of a series of nonlinear models for the carbon cycle describing the interactions in a soil-vegetation system. The role of positive nonlinear feedback between productivity and humus content in the development of the soil stability mechanism was considered, as well as the role of negative feedback between humus content and erodibility. A comparative analysis of stability of automorphic soils of the East European Plain with respect to changes in some parameters of the carbon cycle was performed.
