Vegetation and structural grounds of Arctic

Relation between vegetation and structural grounds is investigated on the example of arctic tundra of Wrangel Island. Ordination of sytaxa in the axes of granulometric composition, polygon diameter and increased of central part of the polygon under its borders were made. It was set a stochastic relationship of vegetation and structural grounds: one structural-morphological type of soil corresponds to several syntaxa and one syntaxon can occur in several types of structural grounds.
