| 摘 要： | 以某城区土壤表层中As、Cd、Cr、Cu、Hg、Ni、Pb、Zn 8种重金属元素作为评价因子,采用surfer8.0软件对城市5个类别区域中的8种重金属分布特征进行了研究,并根据国家土壤环境质量二级标准为评价标准,以单因子指数法和尼梅罗综合指数法为评价方法,对5个类别的区域污染程度进行了探讨。结果表明:该市工业区、交通区属于严重污染区,生活区属于重污染区,公园绿地属于污染区,山地属于轻污染区。

| Abstract: | Taking 8 kinds of heavy metal elements(As,Cd,Cr,Cu,Hg,Ni,Pb and Zn) in the surface soil as evaluation factors,the author studied their spatial distribution characteristics in the soil of 5 types of regions in a city by the software surfer 8.0.According to the national soil environment quality secondary standards,the heavy metal pollution degree of 5 types of regions in the city was evaluated by using the methods of single-factor pollution index and Nemerow synthetic pollution index.The evaluation results indicated that the industrial region and traffic region were severely polluted,the living region was heavily polluted,the park and greenbelt were polluted,and the mountainous region was mildly polluted. |
