| 摘 要： | 采集扬州市中心城区道路两侧绿化带中的土壤样品,分析其中Cu,Pb,Zn,Cd,Cr的含量及其空间分布特征.结果表明:样品中Pb,Cr,Cu,Zn,Cd的质量分数的平均值分别是背景值的2.69,0.86,3.16,3.60,45.02倍,重金属的污染严重且分布不均匀;采用SPSS软件分析各重金属质量分数之间的关系,可知w(Pb)—w(Zn),w(Pb)—w(Cd),w(Pb)—w(Cr),w(Pb)—w(Cu),w(Cu)—w(Cr),w(Zn)—w(Cd),w(Cd)—w(Cr),w(Cu)—w(Cd)之间有着极显著的正相关关系;采用地积累指数法进行污染评价,其中Cd已达到了重度污染.

| Abstract: | The research analyzes the contents and spatial distribution patterns of Cu,Pb,Zn,Cd,Cr in soil samples,which are collected from both sides of the road greenbelt at central district in Yangzhou city.The results indicated that the average contents of Pb,Cr,Cu,Zn and Cd are 2.69,0.86,3.16,3.60 and 45.02 times of soil background values respectively.The soil is seriously polluted by heavy metals and the elements Pb,Cr,Cu,Zn and Cd are distributed uneven in the investigated areas.The correlation analysis of five ... |
