对广州市番禺区农田土壤中As、Hg、Cu、Zn、Ni、Pb、Cr、Cd等8种重金属的含量进行分析，并参照国家土壤环境质量标准（GB 15618-1995）中的二级标准，采用单因子污染指数法和内梅罗综合污染指数法，对其重金属污染程度进行评价。结果表明：42份土壤样品中，镉的污染最普遍，其次是汞。8种重金属元素之间存在低度或显著性的线性正相关，具有同源性。

The paper makes analysis on contents of 8 heavy metals such as As、Hg、Cu、Zn、Ni、Pb、Cr、Cd in cropland soil in Guangzhou Panyu District, and refers to the II grade standard of the National Soil Environmental Quality Stan-dard (GB 15618-1995), adopts odd gene polution index method and Nemero coligation polution index method to evaluates heavy metal pol ution degree. The result shows that cadmium pol ution lists the ifrst and mercury pol ution is the second in 42 soil samples. There are positive correlations of low limit or notable linearity between 8 kinds of heavy metal elements. They are provided with the auto polyploidy.
