摘  要：
通过野外采样和室内分析,对山西省晋城市煤矿区周边农田土壤中Cd,Cu,Zn,Pb,Cr这5种重金属含量进行测定,并利用地累积指数评价污染等级,利用相关分析及主因子分析法进行主要来源分析。结果表明,晋城市煤矿区周边农田中的土壤重金属含量除Cu和山西省背景值相近之外,Cd,Zn,Pb,Cr分别是山西省背景值的1.5,1.2,1.7,1.5倍。地累积指数评价表明,凤凰山矿周边土壤重金属地累积指数大小排序为Pb>Cr>Cd>Zn>Cu,其中,Pb和Cr属于轻度污染;王台铺矿周边土壤重金属地累积指数大小排序为Pb>Cd>Cr>Zn>Cu,其中,Pb,Cr和Cd属于轻度污染。因子分析表明,Zn,Cu主要来源于土壤母质;Cd,Cr,Pb含量与煤矿区的人类采矿活动关系密切。

摘  要：
Based on field sample collection and laboratory analysis,soil samples in farmland around Jincheng city mining area were monitored for contents of 5 heavy metals(Cd, Pb, Cr, Cu, Zn)and analyzed by geo-accumulation index, correlation analysis, and factor analysis. The results showed that Cu in soil was similar to background value in Shanxi province. Zn, Cd, Pb, Cr in soil were greater than background values measured in Shanxi province. The results of pollution assessment showed that the soil around Lantau Peak mining area was slightly contaminated by Pb, Cr. The soil around Wangtaipu mining area was slightly contaminated by Pb, Cr, Cd. Zn, Cu mainly came from the soil parent material, there was a close relationship between Cd, Cr, Pb and coal mining area mining activities in human.
