摘　　要：分析测试了青海某铜矿区土壤重金属元素(As、Cd、Hg、Pb、Cu、Zn、Cr、Ni)含量,研究了对照区土壤似背景值,采用单因子指数法、内梅罗综合污染指数法、地累积污染指数法评价了矿业活动区土壤重金属污染状况。结果表明,除废石堆场周边区域极个别的土壤样品As、Pb、Cu、Cd元素超标外,矿业活动区土壤环境质量良好;对照区土壤似背景值与青海省土壤元素背景值相当,不是重金属高背景区。Contents of heavy metal elements（As,Cd,Hg,Pb,Cu,Zn,Cr,Ni）in soil samples from one copper mining activity area in Qinghai Province were analyzed and measured.Background-like values of the soil in control area were studied.Contents of heavy metal elements were evaluated based on Single Factor Index Method,Nemerow Multi-Factor Index Method and Muller＇s Geo-Accumulation Pollution Index Method.The results show that the soil quality in mining activity area is good except that contents of As,Pb,Cu,and Cd elements in a small amount of samples from areas around waste rock yard are higher than the secondary standard of GB15618-1995.Background-like values of soil in control area are similar to those of soil elements in Qinghai Province,proving a non-heavy metal high-background area.

关 键 词：矿业活动区 重金属污染 土壤似背景值
