Abstract.

The object of this work is the polar landscapes of Eastern Chukotka. The research task is to determine the nature and specificity of geological and geomorphological structure of the territory in typical and anomalous environments of cryolithomorphogenesis. The goal consists in the theoretical and practical studies of sustainability and plasticity of the polar geosystems on the background of climatic changes, amid the conflicting interactions between continentality and oceanicity. Special attention is given to the detailed analysis of morpholythogenic effects of the typical and anomalous (extreme – critical and crisis, as well as disastrous) processes and factors. The main conclusion lies in the following: in the course of development of the northern territories and increased interference in their natural environment, all permafrost processes are activated, with the leading role of thermokarst. Special contribution into the study is defined by the fact that, in the context of the upcoming continentalization of climate and assumed conservation the territory in Eastern Chukotka, the traceable natural risks are reducing, and the geosystems, most commonly, retain their initial sustainability. The exogenous crisis situations and disasters are forecasted, which allows making adjustments to the practice of optimal natural resource management. The scientific novelty lies in tracing the sustainable development of the territory, considering not only the compound, but also thorough complexation of the living and fossil.
