摘　　要：以徐州市三环南路沿线土壤为研究对象,经过野外调查取样和室内分析,对路旁土壤重金属污染及相关性进行了研究。结果表明:不同断面同一重金属含量之间存在显著性差异,这与重金属的种类、来源有关外,还与公路旁有无防护林及防护林的稠密度有关;土壤重金属污染最主要的贡献者是Zn,来自于机动车轮胎的磨损;根据土壤重金属元素之间及重金属与土壤理化性质之间的相关性分析可知,重金属Cu、Cr、Zn和Pb并不是来源于自然来源,而与人为来源有着紧密的关系。Taking the soil along third ring south road of Xuzhou city as research object, this paper researched on the soils pol- luted by heavy metals and correlations through sampling outside and indoor analysis. The results show that contents of the same heavy metal vary significantly in different sampling transects. In addition to types of heavy metals and sources, the availability of sheherbelts and density of shelterbelts are influencing factors. Zn, a major pollution factor, comes from the abrasion of motor vehi- cle tires. The result showed that heavy metals of Cu, Cr, Zn and Pb were not derived from natural sources, but closely related to human behaviors.
