在重庆市旱作粮地、稻田土壤、蔬菜基地、植烟土壤、果园土壤、茶园土壤、淹没区土壤和主城区土壤8种功能类型的土壤上采集了1076个土壤样品，分析了As、Cd、Cr、Cu、Hg、Ni、Pb、Zn等8种重金属赋存量，并采用富集系数、内梅罗指数、地质累积指数和潜在生态危害指数4种方法评价其重金属污染状况。结果表明，重庆市土壤优先控制的重金属元素为Cd、Hg，优先控制的功能类型土壤为主城区街道土壤、植烟土壤和旱作粮地。

The respective contents of 8 heavy metals, including As, Cd, Cr, Cu, Hg, Ni, Pb and Zn, within 1 076 soil samples of 8 sorts of func-tional land of arid grain field, paddy field, vegetable farm, tobacco field, orchard, tea garden, reservoir inundation zone and urban district in Chongqing City, were measured. Then, the distribution of those metals'pollution was assessed by enrichment factor, Nemerow index, geoaccu-mulation index and potential ecological risk index respectively. As demonstrated by results that most attention needs to be paid in controlling the heavy metals of Cd, Hg, and in soil heavy metal management within urban areas, tobacco fields and arid grain fields.
