| 摘 要： | 通过对廊坊39个样点根系土中As、Cd、Cr、Hg、Pb共5种重金属元素各形态含量的统计与分析,总结出该区根系土重金属元素形态组成特征,初步分析了各重金属元素在土壤中的地球化学行为。运用相关性分析方法,对5种重金属元素有效态含量与全量及土壤pH、TOC的相关性进行分析。根据分析结果,重金属元素有效态含量的高低不仅受其全量的影响,而且与土壤pH、TOC亦有着密切关系。该结论为评估廊坊表层土壤重金属元素污染程度提供了理论依据。

| Abstract: | According to the statistics and analysis on contents of 5 kinds of heavy metal elements such as As,Cd,Cr,Hg and Pb under different forms from 39 samples of root soil in Langfang area,this paper sums up the characteristics of form composition,and analyzes the geochemical behavior of the heavy metal elements in the root soil preliminarily.By using the correlation analysis method,the effective form contents and total contents of 5 kinds of heavy metal elements,pH and TOC of the soil are analyzed to come to a c... |
