///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.
