NTEGRATED STUDY OF SOME ROADSIDE PHYTOCENOSIS OF TOBOLSK
Article presents the results the study of anthropogenic roadside phytocenoses city of Tobolsk. Studied the state of herbaceous vegetation. As a result of work done carried out: a) the selection of sites with anthropogenic impact; b) description of the composition of the grass; c) counting the number of individuals of all plants at designated sites; g) defines the main pollutants (zinc, copper, iron, cadmium, cobalt, lead, chromium, arsenic, mercury, manganese, nickel) and their accumulation in the soil and total biomass of observing sites.
