通过对贵州草海湿地国家级自然保护区土壤采样实测重金属含量数据分析及土壤污染评价,结果表明:草海土壤重金属含量对照国标土壤二级限制值主要超标元素是镉、锌、镍,其次是砷、铬、铅,而铜、汞未超标。通过土壤污染物分担率和内梅罗污染指数总体与分区评价草海盆地型湿地重金属污染,反映出接近污染源区域和水流通道地段重金属污染加重。
通過對貴州草海濕地國傢級自然保護區土壤採樣實測重金屬含量數據分析及土壤汙染評價,結果錶明:草海土壤重金屬含量對照國標土壤二級限製值主要超標元素是鎘、鋅、鎳,其次是砷、鉻、鉛,而銅、汞未超標。通過土壤汙染物分擔率和內梅囉汙染指數總體與分區評價草海盆地型濕地重金屬汙染,反映齣接近汙染源區域和水流通道地段重金屬汙染加重。

Heavy metals in soil samples from Caohai, a national nature reserve, were measured. Compared with the national standards for class-II soil limit values, the results showed that contents of heavy metals excessive in soil were Cd, Zn, Ni, As, Cr and Pb, while contents of Cu, Hg were not exceeded. Indices of N. L. Nemerow pollu- ted evaluation and soil participation rate showed that heavy pollution became relatively serious near pollution sources and related water channel sections of the basin wetland ecosystem.
