中文摘要：
对深圳城市主要公园和道路绿地土壤Cu、Zn、Pb、Cd含量状况进行取样调查分析。研究结果表明，绿地土壤重金属含量与土地利用类型有关，表现为道路绿地土壤Cu、Zn、Pb平均含量高于公园绿地土壤，而Cd平均含量则相反。采用不同土壤重金属污染评价方法对深圳城市绿地土壤进行的环境质量评价均表明深圳城市绿地土壤Cd污染现象显著。在考察的四种重金属元素中，Zn含量与土壤有机质、pH有关，其中pH对Zn含量的影响相对较大；土壤Cu与Pb、Zn呈直线相关，表现出相互依存的关系。
英文摘要：
Urban soil of green ground in Shenzhen city was sampled in order to investigate the contents of heavy metals in the soil near main parks and roads. The results showed that the contents of heavy metals were related with land - use types. Average contents of soil Cu, Zn, and Pb were higher in the soil of parks compared with those near roads, but soil Cd showed an opposite trend. The environmental effect evaluation with various methods showed that there was a phenomenon of Cd pollution of the soil, especially in parks green ground. The content of Zn showed an significant correlation with the content of soil organic matter and pH.
