Methodological bases of the estimation of stability of soil-vegetative complexes of the extreme northeast of
Problems of an expert-look-ahead estimation of the soil-vegetative complexes (SVC) stability of permafrost region to anthropogenous effects are discussed. On the basis of properties of soils, climatic indicators and of some other features the soil-ecological estimation of landscapes of region under considiration is carried out. Characteristics of 7 groups SVC on degree of stability to various influences and character of anthropogenous processes development are given.
