Abstract: In order to reveal the impact of urbanization and industrialization activities on soil environmental quality in a region, the research focused on outskirts of city to combine ministry of Baoji. The soil samples were collected from sampling sites, and measured heavy metal contents. To analyze and assess the pollution degree by using the single pollution index, the composite pollution index, the geoaccumulation index, N.L.Nemerow index and H?kanson’s potential ecological risk index. The results showed that the mean contents of all metals except Cd were lower than their environmental quality secondary standard values for soils (GB 15618-1995). The results of N.L.Nemerow index showed that most of the sampling point of heavy metal contaminated level was cleaner, slightly polluted in the sampling point of S3 and S5, moderate level of pollution in the sampling point of S7, heavy pollution in the sampling point of S6. The results of the geoaccumulation index showed that the order of Cd≥Cu≥Pb≥Zn≥Cr. The individual potential ecological risk of Cd in all heavy metals was the most important. The individual potential ecological risk of heavy metals ranked in order of Cd＞Cu≥Pb≥Cr≥Zn. The results of the integrated pollution indexes of heavy metals were considerable risk, moderate risk in the sampling point of S3, S5 and S10, the rest of the sampling points were low risk. Analysis of pollution sources showed that Pb, Cu, Cr and Zn might had identical anthropogenic and natural sources, while Cd might have the same source in outskirts of city to combine ministry of Baoji.
