Assessment of the stability of permafrost landscapes in the developed territories of Western Yakutia

Using GIS technologies, a Map of the resistance of permafrost landscapes of the developed territories of Western Yakutia on a scale of 1:1,000,000 to anthropogenic impacts was compiled. The ice content of the underlying rocks, soil temperature, the thickness of the active layer and the distribution of cryogenic processes were accepted as stability criteria. At the same time, a point system for assessing the stability of landscapes was used. Spatial analysis of permafrost landscapes showed that the largest areas are occupied by stable landscapes (66.8%), relatively stable and relatively unstable landscapes occupy 19,5 and 13,7%, respectively.
