摘要
利用因子分析对唐海县191个浅层土壤的53种元素进行分析,提取了7个主因子。根据主因子组合中的标识元素判别当地8种重金属(Cu、Zn、Ni、Cr、Pb、Cd、As和Hg)来源。结果显示Pb、Zn、Ni的主要来源是土壤成土母质。Cr和Cu一部分源于土壤本底,另一部分来源于外界污染造成的元素叠加。Cd具有独立的外源成因。Hg的来源较为复杂,煤烟尘也许是当地Hg的来源之一。
53 elements were analyzed by factor analysis in 191 topsoil samples on Tanghai country,Hebei Province,and 7 main factors were selected.Sources of 8 heavy metals（Cu,Zn,Ni,Cr,Pb,Cd,As,Hg）were remarkably different according to reference elements.The results showed that Pb,Zn and Ni mostly come from parent minerals.Contents of Cr and Cu were affected by both soil geogenic origin and anthropogenic pollution.Cd has specialty outside source.Origin of Hg was complex.
