摘要(Abstract)：

以安徽省淮南市为研究对象,共采集99个土壤样品,分析土壤中As、Cd这2种重金属的含量,运用克里金插值法分析其空间分布情况,采用地累积指数法及潜在生态风险指数评价该地区重金属累积程度和生态危害程度,采用PMF5.0分析污染源。结果表明,该地区不同土地利用方式表层土壤中As、Cd超过淮南市土壤背景值的采样点占比分别为非矿区农田(As 0)、矿区农田(As 10.42%)、林地(As 12.50%)、城市土壤(As 15.38%)和城市土壤(Cd 7.69%)、非矿区农田(Cd 10.00%)、矿区农田(Cd 12.77%)、林地(Cd 31.25%);重金属As和Cd的污染区为凤台县矿区农田(煤矸石堆放点)、八公山林区和上窑林区;重金属地积累指数I_(geo)数据集中在0以下,属于无污染;As的潜在生态风险指数E■最大值<40,属于轻微污染。除八公山区的Cd的E■最大值>80,属于强污染外,其他部分属于轻度污染到中度污染。总的来说,淮南地区土壤重金属富集区域少,并没有因为采煤活动给土壤环境造成重大影响。
