Theoretical bases for soil-ecological and functional zoning of urban areas are provided based on the studies of the biological activity of soils in the urban landscape (Kemerovo city territory). The results of geochemical analysis of soil samples are analyzed. The possibility of using calculations of dose-effect dependencies for the implementation of soil-ecological zoning of the urban territory is considered. “Dose” was measured by indicators of heavy metal concentration in the soil (Cu, Zn, Fe, Co, Ni, Cr, Mn, Cd, Pb) , “effect” was measured by the data obtained in the preliminary study of soil samples for the activity of enzymes (catalase, urease, dehydrogenase, invertase), and cellulose breaking activity of soils and humus content. The studied plots were divided in soil-ecological zones by the method of agglomerative clus-tering. A linguistic dictionary for naming the acquired terms was compiled, a brief description of selected soil-ecological zones is presented.
