| 摘 要： | 目的]对贵州省罗甸县艾纳香种植基地土壤中5种重金属（Pb、Cd、Hg、As、Cu）污染现状进行评价。方法]选用《土壤环境质量标准》（GB15618-1995）二级标准和黔南州土壤重金属背景值作为土壤评价标准,采用综合污染指数法与尼梅罗综合指数法进行污染现状评价。结果]贵州省艾纳香种植基地土壤重金属含量水平差异较大,变异系数为13.70%~65.79%,均达国家土壤环境质量标准（二级） 综合污染指数与尼梅罗综合指数结果表明,调查区域内土壤未被污染。但结合艾纳香对土壤中重金属的吸收富集特征发现,土壤中重金属Pb、Cu、Cd对艾纳香均存在污染。结论]土壤重金属污染的评价仅用总量进行分析是不够的,植物种类及土壤中重金属形态的变化也应考虑在内。

| Abstract: | Objective] The aim was to evaluate pollution status of five heavy metals(Pb,Cd,Hg,As and Cu)in soils from Blumea balsamifera planting base in Luodian County,Guizhou Province.Method]In accordance with Grade Ⅱ criteria of Soil Environmental Quality Standard and background values of soil heavy metals in the region,evaluation of heavy metals pollution status in the soil were conducted by synthetical pollution index method and nemerow pollution index method.Result] The study showed that the content difference of the heavy metals in soils from Blumea balsamifera planting base in Guizhou Province was more large,and the variance coefficient ranged from 13.70% to 65.79%.Results of synthetical pollution index and nemerow pollution index showed that the soils were not polluted.In combination with the accumulation feature of Blumea balsamifera to heavy metals from the soil,however,it was found that the pollution of the heavy metals(Pb,Cu and Cd) existed in soils from Blumea balsamifera planting base.Conclusion] Evaluation of heavy metals pollution in the soil by the total amount was not enough,thus the type of plants and morphology change of heavy metals should also be taken into account. |
