| 摘 要： | 在长株潭地区系统采集地表土样,对土壤中As、Zn、Cu、Pb、Ni、Cd、Cr进行分析,采用单因子指数法和综合指数法分别对土壤的污染状况进行评价。结果表明:AS、Cd、Cr、Pb、Zn显示了很强的富集且分布极不均匀,如Cd的变异系数高达212%,且已达到了严重污染的程度。这些重金属元素的污染严重度的排序为Cd>Zn>Pb>As>Cr>Cu>Ni。在空间分布上,污染严重度的排序为株洲>湘潭>长沙,且工业区明显大于非工业区;在受到极度污染的土壤类型中,以潮土所占的比例最大,红壤及稻田土次之。

| Abstract: | oil samples were systematically collected from the ground surface in the Changsha,Zhuzhou and Xiangtan areas and analyzed for the elements including As,Zn,Cu,Pb,Ni,Cd and Cr.The pollution extent of soils was evaluated by using the single factor exponential method and integrated exponential method.It is revealed that the elements As,Cd,Cr,Pb,and Zn are highly enriched and distributed extremely uneven in the investigation areas.For example,the coefficient of variation of Cd is as high as 212%,reaching the lev... |
