Abstract


The condition of wood plantings in forest-park ecosystems of megalopolises and performance of private sanitary and ecological functions by them substantially depends on intensity of influence of anthropogenic factors of the city. Intensity of these changes is corrected also by structure of tree species: it is established that for the centenary period (1909—2000) pollution of soils of LOD by heavy metals considerably increased: on lead — at 40—50 time, on copper at 17—24 time and to zinc — 4—9 times. Accumulation of heavy metals in the soil is closely connected with removal from a pollution source (city highways, the industrial enterprises), and also with a complex of properties of the soils caused by its consolidation at intensive recreational loading, and also from structure wood and shrubby plantings.
