Some methodical ways of permafrost-ecological conditions estimation under economic development in terms of northern geosystems sustainability to the manifestation of dangerous cryogenic processes are described. All types of evaluation studies are carried out on the landscape basis with the help of expert scores. The mechanical load intensity is compared with natural landscape stability gradations using the matrix method. The various intensities of anthropogenic load are ranked with regard to the development type based on type of mechanical damage, residual deer capacity, the vegetation recovery rate, and the share of disturbed land. Scientific and methodological approaches of this evaluation can be applied in engineering geocryology, at predesign stages of the research, and for strategy decision-making for cryolithozone development.
