| 摘 要： | 通过对上海市不同土地利用方式下绿地土壤中重金属Cu、Zn、Pb和Cr的调查研究,发现工业区和交通区绿地土壤中Cu、Zn、Pb、Cr的平均含量均显著高于大学、公园及居民区。与上海市土壤环境背景值相比,不同土地利用方式中4种重金属均存在一定富积。就单项污染指数而言,Cu、Pb和Cr的污染程度大小依次为工业区>交通区>大学≈公园≈居民区,而Zn为交通区>工业区>大学≈公园≈居民区;就内梅罗综合污染指数而言,工业区和交通区污染较严重,分别有54.17%和67.9%的土壤达重度污染;而公园、大学及居民区绝大部分土壤为轻度污染,分别为73.1%、100%和60%。

| Abstract: | Cu,Zn,Pb and Cr contents of urban green-belt soil taken from different land use types in Shanghai were studied.The results showed that the average contents of Cu,Zn,Pb and Cr in soil from industrial districts and traffic areas were significantly higher than those from urban parks,universities and residential areas.Compared with their background values in Shanghai soil,concentrations of these four heavy metals were remarkably higher,implying their accumulation in the sampled areas.For single pollution index ... |
