ECOLOGICAL AND GEOCHEMICAL STUDY OF URBAN ECOSYSTEMS OF STAVROPOL

Abstract

We report the results of soil geochemical and
biogeochemical research within the landscape structure and
functional zones of Stavropol, as well as analyze the distribution
of heavy metals in soils of the city, contamination of
urban soils and its dynamics. The levels of accumulation of
trace elements in some species of woody and herbaceous
plants with respect to the natural background are estimated.
The dependence is obtained for the concentrations of chemical
elements in earthworms and in soils, as well as for their
relation with certain soil characteristics.
