摘要：

Relationship between the characteristics of vegetation (above-ground and underground phytomass, above-ground biomass, species composition and projective cover) and soil properties (power of organogenic and root-inhabited layers, humus content in the 1-20 cm layer, thickness of abiotic alluvium) allowed developing biological indices and criteria for quantitative estimation of stability, degree of physical and general degradation, and dynamics of self-recovery of disturbed soil-vegetation cover in tundra. An analytical description of the process of vegetation and soil self-recovery is given to determine duration of various degradation levels and total duration of recovery under different conditions of water regime with the accessible minimum of initial information.
