摘　　要：通过对108国道和潼江支流魏刘河二侧土壤中重金属元素的富集系数(EF)计算研究,总结了该研究区公路(Ro型)和河流(Rv型)二种EF值典型特征,同时指出该研究区河流为污染源的贡献者,而公路通过改变土壤物理结构,造成污染的程度增大。Through the study of enrichment factors(EF) of heavy metals in soil along the two sides of national highway NO.108 and Weiliu River which is a tributary of Tong River,this paper concludes the typical features of the two enrichment factor values of the highway(Ro model) and river(Rv model) in the study area.Besides,this paper points out the river is the main pollution source,and the highway increases the pollution degree by changing the soil's physical structure in the study area.

关 键 词：重金属污染 富集系数 108国道 魏刘河
