摘　　要：以吉林省永安煤矿区为研究区域,分别采用Pearson相关系数法、富集因子法、地质累积指数法和潜在生态危害系数法,对矿区土壤和近地表大气尘的重金属污染状况进行了综合性评价。Pearson相关系数法表明,土壤与近地表大气尘中重金属的相关性较高。富集因子指数分析表明,近地表大气尘重金属污染情况受人为活动的影响较大,污染亦较为严重。地质累积指数分析结果表明,土壤及近地表大气尘中V和Cr属于清洁级别,Zn、As、Pb、Cu、Cd属轻度污染级别。潜在生态危害指数结果表明,土壤和近地表大气尘中Cd元素的潜在生态风险最高,Cu其次,其余元素处于轻微生态危害至中等生态危害风险状态。In order to evaluate the degree of the pollution status of the area,Yong＇an coal mining area in Jilin,The heavy metal pollution in the soil and air dust near ground in the area was comprehensively evaluated by using the Pearson correlation coefficient method,enrichment factor method,geologic accumulation index method and potential ecological hazard factor method. Pearson＇s correlation coefficient method shows that soil has a high correlation with heavy metals in air dust near ground. The enrichment factor index indicates that the heavy metal pollution in Yong＇an mining area is largely affected by human activities and the pollution situation is more serious. Geological cumulative index results show that V and Cr in soil and air dust near ground are clean levels and Zn,As,Pb,Cu and Cd are mild pollution levels. The results of potential ecological risk index show that the potential ecological risk of Cd is the highest,followed by Cu,and the rest of the elements are in a slight ecological risk to the middle ecological risk.
