为了解贵州省黔西北铅锌矿区土壤中重金属Cd、Pb、Zn的污染现状,采取查阅文献和现场采样、检测分析等方法进行了调查研究.结果表明:该地区土壤中重金属Cd、Pb、Zn的平均含量分别为3.3 mg/kg、165.2 mg/kg和454.33 mg/kg,土壤中Pb、Zn含量均与Cd的含量有极显著的正相关性,且均高于国家和贵州省的土壤背景值.%The pollution status of Cd. Pb and Zn in northwestern Guizhou was investigated by consulting literatures, site sampling, detecting and analyzing in the lab. The results showed that the average contents of Cd, Pb and Zn in the soil were 3. 3 mg/kg, 165. 2 mg/kg and 454. 33 rag/kg respectively. Meanwhile, the Cd content in the soil was very significantly positively correlated with Pb and Zn, which were all higher than the background values of soil in the nation and Guizhou Province.
