In this thesis, the present situation of heavy metals pollution and the physical and chemical properties of soils and the enrichment situation of heavy metals (Cd、 Hg、 Pb and Cr) in the vegetable body in the Harbin city greenbelt was investigated and evaluated. The results were showed as follows:The four heavy metals all polluted greenbelt soil by different degree in Harbin. The pollution of hydrargyrum is the most serious and reaches to the heavy pollution. The next pollution is plumbum, cadmium and chrome.
