The relevance of the research is due to the poor study of permafrost-geoecological conditions and the ever-increasing role of their negative impacts on modern economic development of the Lower Amur region. It is shown that one of the significant limiting factors of development is permafrost and dangerous cryogenic processes in the region, their activation under global warming. The object of the research is permafrost of the plain and mountainous territories of the Lower Amur region. The subject is the limiting factors of economic development of the Lower Amur region, caused by dangerous manifestations of cryogenic processes in various geomorphological conditions. The purpose and objectives of the research are to assess the state of permafrost and dangerous cryogenic processes on various landforms and their impact on modern and prospective objects of logistics infrastructure during the development of plains and adjacent territories. Methods and methodology are as follows: based on the analysis of available maps, ESRI ArcGis Imagery satellite images and field work data, the main forms of macro-, meso- and microrelief and the cryogenic processes associated with them are identified. Based on the geomorphological confinement of hazardous cryogenic processes to certain relief forms, natural areas of specific economic development are identified. To determine the degree of hazardous cryogenic processes impact in areas of natural areas of specific economic development, the main factors differentiating natural areas by permafrost-geoecological conditions and permafrost-geoecological areas by the degree of favorability of economic development are identified. The practical use of the research results is shown in the analysis of the route of the existing winter road “named after P. Osipenko – Tugur”, located within the Lower Amur region
