Morphological structure of cryogenic landscapes of the Bolshezemelskaya tundra has been analyzed at the level of groups of natural boundaries according to the origin, age, ground composition and absolute elevations. Quantitative characteristics (in % of landscape type area) of areal distribution of groups of natural boundaries (forest, tundra, bog, peat) and permafrost have been determined for each geological-genetic type of landscapes. In addition, the area of closed taliks has also been estimated for each type of landscape and for the entire area of the tundra zone underlined by continuous permafrost. The relationship between various groups of natural boundaries and the areas of permafrost-affected and non-permafrost soils are estimated on the basis of quantitative analysis of landscape morphology. The variability in the landscape structure of the Bolshezemelskaya tundra both in latitudinal direction and depending on absolute altitudes of the interfluves has been shown.
