Abstract
Results of the classification of ecosystems over the matrix of average quotient of similarity are reported. Initial coefficients were calculated at first separately over the four components comprising the ecosystem. These components (blocks) include the underground part (humus of soil, mortmass, and underground phytomass), top vegetation, as well as invertenrates and vertebrates. Mismatch of boundaries in separate blocks of the ecosystems and in comparisons with the inhomogeneity of ecosystems in general was demonstrated. These differences manifest themselves both in the typological and in the typological-chorologic analysis. The revealed features of the territorial interchange in the indicated blocks generate continuity of ecosystems and the conventional character of all the classifications and drawn boundaries.
