摘　　要：为了研究矿山不同用途土壤中重金属分布规律、重金属元素之间相关性、重金属污染程度、重金属有效性及重金属污染迁移规律等,探讨铅锌矿山土壤重金属复合污染状况。收集并分析若干份铅锌矿不同用途土壤重金属富集的实测数据,用统计分析软件SPSS对各重金属之间相关性进行分析,并采用单因子指数法和内梅罗综合污染指数法对土壤重金属污染程度进行评价,统计并分析17份铅锌矿不同用途表层土壤Zn、Pb、Cd、Cu有效态含量数据资料,评价并研究8份铅锌矿不同用途不同深度土壤层重金属含量资料,对我国铅锌矿重金属污染土壤规律进行初步探讨。In order to study the pollution, distribution and migration, and correlation of heavy metals in lead-zinc mines, different soil samples polluted by heavy metals in 41 lead-zinc mines were examined and analyzed by SPSS. In addition, the pollution level of soil heavy metals was evaluated by the methods of single factor pollution index and comprehensive pollution index. In the meantime, the distributions of available Zn, Pb, Cd, Cu in different topsoil of 17lead-zinc mines were analyzed, as well as the heavy metals pollution levels from different depths of soil layer in 8lead-zinc mines. Subsequently, the preliminary research on the law of soil polluted by heavy metals in lead-zinc mines was conducted.
