| 摘 要： | 河北省白洋淀洼地是一个大型天然平原洼地,在洼地的深、浅层土壤中均发现了以Cu、Pb、Zn、Cd为主的多变量地球化学异常。运用地球化学特征法、参考元素法及多元统计法,对深、浅层土壤Cu、Pb、Zn、Cd异常的性质和成因进行了判别。结果表明,深层土壤异常与特定的地球化学沉积环境有关,以自然地质作用成因为主,而浅层土壤异常具有典型的二元叠加特征,以人为源的输入为主。

| Abstract: | The Baiyangdian billabong of Hebei province is a large natural plain billabong,in which multi-variable geochemical anomalies,especially Cu,Pb,Zn,Cd,were detected in both topsoils and deepsoils.This study distinguished the characteristics and origins of the Cu,Pb,Zn,Cd anomalies in topsoils and deepsoils by the method of geochemical characteristics,the method of reference elements and the method of multi-variate statistics.The result indicates that the anomalies presenting in deepsoils were related to the specific geochemical deposition environment that resulted mainly from natural processes;however,the geochemical anomalies presenting in topsoils have typical characteristics of dualistic superposition,and mainly resulted from anthropogenic activities. |
