| 摘 要： | 通过对湖北利川水杉母树管理站土壤中Cd、Cr、Cu、Pb、Zn五种重金属含量进行测定,采用地积累指数法及潜在生态危害指数法分别评价其污染水平,结果表明水杉母树管理站的土壤重金属具有污染。地积累指数法得出Cd受到中等程度的污染,Igeo分级为2级,其他四种重金属无污染。生态危害指数法得出单一金属潜在生态风险系数上Cd的已经可观,其他四种金属为低,多金属潜在生态风险指数提示已经达到中等。

| Abstract: | According to the concentration of heavy metals（Cd,Cr,Cu,Pb,Zn） in Hubei Lichuan Metasequoia Mother Trees Administrative Station,methods of index of geoaccumulation（Igeo） and potentional ecological risk index（RI） were used to evaluate heavy metal pollution.Pollution Results indicated that Metasequoia mother trees administrative station has been polluted by heavy metals.Cd has moderate pollution with the method of Igeo and Igeo value is two.The other four is non-polluting with the method of Igeo.Cd has observable pollution with the method of single metallic RI.The other four is low with the method of single metallic RI.Combined metallic RI has reached the middle level. |
