Self-regeneration factors and mechanisms of mountain-tundra landscapes of Chukotka

Stability of mountain-tundra landscapes of Chukotka is treated as the capacity of geosystems for natural restoration. In this case study of a number of mining sites with a restoration period of 25-40 years, the effect of exogenous and biogenic factors is analyzed. It is concluded that the mountain-tundra landscapes are distinguished by plastic stability and that phytogenic and cryogenic processes have a dissimilar influence on geosystem restoration.
