| 摘 要： | 本文分析研究了青岛市工业区、商业区、居民区、农业区、旅游区表层土壤中重金属Cd、Cr、Cu、Ni、Pb、Zn的含量，采用Mul1er地积指数法对其污染状况进行评价，结果表明：Cd在各功能区含量均高于国家土壤环境环境质量二级标准，其浓度大小顺序为：工业区(0.807mg/kg)>商业区(0.748 mg/kg)>居民区(0.642 mg/kg) >农业区(0.532 mg/kg) >旅游区(0.356 mg/kg)，Cr、Cu、Ni、Pb、Zn浓度均低于国家二级标准；按Mul1er地积指数法评价，Cd和Ni在五个功能区表层土壤的地累积指数为1，均属于轻度-中等污染，Cr、Cu、Pb 在不同功能区污染水平略有不同，Zn在五个功能区地累积指数为0，为无污染。由此可知，青岛市表层土壤均受到Cd和Ni污染，未受Zn污染。

| Abstract: | This paper have analyzed the distribution and the pollution level of Cd, Cu, Ni, Pb and Zn in industry area, business area, resident area, agriculture area and tour area in the city of Qingdao. We evaluated the pollution of heavy metal in soil by using Muller geoaceumulation index; the concentration of Cd was higher than national soil standard two in every ecological function area, The content order of Cd was industry area （0.807 mg/kg）〉business area （0.748 mg/kg）〉resident area（0.642 mg/kg）〉agricuhure area （0.532 mg/kg） 〉tour area（0.356 mg/kg）. The concentration of Cr, Cu, Ni, Pb, Zn were lower than national soil standard two. Cd and Ni are Mild - Medium polution in every ecological function area and their geoaeeumulation index were 1, the pollution level of Cr, Cu and Pb were different, Zn was no pollution in every ecological function area and its geoaceumulation index was 0 according to Muller geoaceumulation index. Industry area, business area, resident area, agriculture area and tour area in the city of Qingdao are polluted by Cd and Ni, but not polluted by Zn. |
