Lysikov A. B. The Influence of Forest on Pollution of Roadside Soils // Forest Science (Lesovedenie). 2010. No 4. P. 50-55 (in Russian). The possibility to diagnose the intensity of contaminating forest biogeocenoses with some air-borne technogenic pollutants was studied in the zone exposed to effects of the Moscow Circle Road by comparing the chemical composition of soils in different microzones of birch parcels. Along with changes in soil acidity and in the content of exchangeable Ca, the total contents of Pb, Zn, and Cu in the upper soil layer of the stem microzone were found to be 1.5 times higher than their concentration in the soil under tree crowns. With distance from the road - a local pollution source, interparcel differences in these parameters were lowered along with decreasing the total pollutant content. Differences in the chemical composition of the top layer of the soils in different parcel zones can be a diagnostic criterion for a kind and intensity of technogenic impact on the roadside forests. The results of this work can help to solve problems related to monitoring of forest biogeocenoses subject to the effects of anthropogenic factors.
