| In this paper, the surface soil samples were collected from a typical mining and metallurgy city in Hubei, the mass ratio of Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn were determined. The spatial distribution characteristics and pollution lever of the 8 heavy metals were discussed. The contribution rate of each source was quantitatively analyzed. The results showed that Cd， Cu， Pb and Zn pollution was severe and had similarly spatial distribution, all were concentrated in working area. High values of Co and Cu were appeared in copper mine. Cd, Cr and Cu pollution were serious, and had great adverse effects on the soil ecological environment. The comprehensive mineral source and copper mine source were the main influence factors in the research area, the contribution rates of heavy metals in soil were 41% and 31% respectively. |
