| 摘 要： | 通过对徐州市九里矿区的表层土壤进行采样测定,进而对该矿区土壤重金属富集与污染状况进行了分析与评价。结果表明,该矿区表层土壤中5种重金属(Cd、Cu、Zn、Pb、Cr)含量均略高于中国土壤元素背景值,土壤中Cd富集程度较高,污染较严重;Cu、Zn、Pb、Cr富集程度较低,污染程度较轻。在GIS环境下利用空间数据插值方法对重金属的空间分布特征研究发现,该城区土壤重金属含量与该区的工矿活动和交通活动等密切相关。

| Abstract: | Based on laboratory analysis of soil samples collected from Jiuli district of Xuzhou,enrichment of heavy metals in the soils was investigated and the soils were evaluated for heavy metal pollution in this paper.Results indicated that the content of 5 types of heavy metals(Cd,Cu,Zn,Pb,Cr) were all higher than Chinese background value of soil elements,among of these heavy metals,the enrichment of Cd was higher and polluted quite seriously;the enrichment of Cu,Zn,Pb and Cr was lower,and not polluted or polluted lightly.Besides,the results indicated that the distribution of heavy metal was closely related to traffic activities and industrial activity etc.based on spatial interpolation under GIS environment. |
