摘　　要：Predictive assessments of the geomorphological systems’ behavior under climate warming in southern Siberia have been performed based on time-series data, using theoretical and empirical models of processes. High sensitivity and fast response of erosional, aeolian, and cryogenic processes to current climatic changes are presented. The current trends under changing functioning conditions of geomorphological systems while maintaining climatic trends have been determined. Areas with different targeting of morpholithogenesis are identified.Predictive assessments of the geomorphological systems’ behavior under climate warming in southern Siberia have been performed based on time-series data, using theoretical and empirical models of processes.
