摘　　要：针对甘肃某金矿矿区及周围土壤,设置了9个土壤采样点,采样分析了铜、铅、砷、汞、镉、铬(六价)和镍7种重金属元素的含量。采用内梅罗污染指数法、地累积污染指数法进行了土壤中重金属的污染情况分析与评价,统计分析各个采样点的综合污染程度,对比分析两种方法的评价结果,两种评价方法均显示砷元素为矿区的主要污染因子,该矿区所在地生态环境脆弱,建议在后续的矿产资源开发利用活动中,加强砷元素的综合回收和利用,减少对环境的污染。Aiming at a gold mining area and the surrounding soil in Gansu province, setting up 9 soil sampling points, the samples analysis that the element contents of the 7 kinds of heavy metal, including copper, lead, arsenic, mercury, cadmium, chromium(6+) and nickel. Analysis and evaluation for the soil heavy metal pollution situation by Mei Pollution Index Method and The Pollution Index Method, statistical analysis of each sample point comprehensive pollution level. Contrasting the analysis and evaluation results of two methods, show that arsenic is the main pollution factor of mining area. The environment of mining area is located the fragile ecological. Suggestions in the mineral resources development and utilization of subsequent activity, strengthen the comprehensive recovery and utilization of arsenic, reduce the pollution to the environment.
