| 摘 要： | 采用三峡库区忠县-万州地区表层土壤的分析测试数据,运用因子分析法对As、Cd、Cr、Cu、Hg、Ni、Pb、Zn 8种重金属元素进行了统计分析,提取了5个主要的因子,得出了这些因子对研究区这8种重金属污染的影响程度,建立了因子与重金属元素之间的对应关系并按相关性对重金属元素进行了分类,同时,结合研究区工业、矿业、农业生产布局对污染来源进行了分析总结。

| Abstract: | According to the testing and analysis data of the topsoil in Zhongxian-Wanzhou district of the Three Gorges Reservoir Area(TGRA),this paper conducted a statistical analysis of eight heavy metals(As,Cd,Cr,Cu,Hg,Ni,Pb,Zn) through the factor analysis method.Five main factors were extracted,the influence of these factors on the heavy metal pollution in the researched district was obtained,and the corresponding relationship between factor and heavy metal element was built.The heavy metals were classified based o... |
