Abstract
On the basis of the data on the air-dry mass of plant species - dominants and subdominants in five life forms (mosses, lichens; herbs; subshrubs; shrubs; trees), quotients of similarity for ecosystems were calculated over the types of formations in the map Vegetation of the West Siberian Plain. By means of the cluster analysis of thus obtained similarity matrix, two classifications were compiled (over apportionments and over groups of apportionments of the indicated map). The calculated self-descriptiveness of the proposed schemes, estimated by the value of included dispersion, is higher by 11-16 % in comparison with division of vegetation on the initial map.
