摘要/Abstract

摘要： 通过对矿区地上典型区域土壤重金属含量的测定，确定了Cd是矿区土壤中重金属污染的特征元素；利用单因子污染指数法、内梅罗污染指数法和潜在生态危害指数法评估该区域土壤重金属污染程度和潜在生态风险.结果表明: Cd的单元素污染负荷指数和内梅罗污染指数平均值分别为4.06和5.32，属于重度污染水平.3个生态修复区域的内梅罗污染指数在2.07~4.57之间，其中南帮自然生态恢复区(SNER)属于重度污染，其他区域为中度污染；矿区土壤重金属潜在生态风险指数介于98.62~224.55之间，SNER区域达到中等危害水平，其余区域为轻度生态危害.

Abstract: By measuring the heavy metal content in the typical area of the mining area， it is found that Cd is the characteristic element of the heavy metal pollution in the mining area. The pollution degree and the potential ecological risk caused by the heavy mental pollution were evaluated by using the single factor pollution index method， the Nemero pollution index method and the potential hazard index method respectively. The results showed that the average values of single element pollution index and Nemero pollution index of Cd are 4.06 and 5.32， respectively， both indicate a heavy pollution. The Nemero pollution index of the three ecological restoration areas are 2.07~4.57， among which the south natural ecological restoration(SNER) area is heavy pollution and the other areas are moderate pollution. The potential ecological risk index of heavy metals in the mining area is 98.62~224.55， the SNER area reaches the medium hazard level， and the remaining areas are evaluated as mild ecological hazards.

Key words: Fushun western open-pit mine, mining area soil, heavy metal pollution, pollution assessment, potential ecological risk
