Based on the results of the research of permafrost soils tundra landscapes formed in the central part of the Tazovskiy Peninsula in cryogenic conditions, data were obtained which characterize the patterns of formation, structure, and properties of soils. The specificity of soil cover distribution and manifestation of soil-forming processes within the investigated area is revealed. The interrelation of variation of soil properties, soil profile structure and cryogenic processes is stated. The discrepancy between the small speed of chemical and biochemical transformation of the initial material under soil formation, rather high speed of carrying out of the released soluble products, considerable influence of the cryogenic processes accompanied with thawing, as well as the cryogenic heaving of clay and peat soil caused by frost penetration in breeds affects the genesis and properties of the considered soils. Depending on the factor-ecological conditions, the combination of soil-forming macroprocesses (cryogenesis, gleying, detritogenesis) best describes the essence of tundra pedogenesis of the investigated area.Keywords:
