摘要
通过对重庆市沙坪坝区大学城新区和老城区绿地土壤Pb的含量及其空间分布特征的分析,并运用地质积累指数和富集指数进行分析得出:大学城新区和老城区绿地土壤Pb的空间分布差异较小,老城区的污染程度大于大学城新区。
The soil Pb contents and its spatial distribution at new and old areas of Chongqing Shapingba University Town were analyzed. And the geological accumulated index and enrichment index were calculated. The results indicated that the differences of Pb spatial distribution in green soil between new and old areas were small and the pollution level at old district was greater than the university town＇ s new district.
