| Abstract: | Spatial distribution,sources and spatial heterogeneity of heavy metals are studied by using geo-statistic approach and ArcGIS in Henghe town,Cixi city in Zhejiang province.Heavy metal pollution in the soil is evaluated by ecological risk index method.The results show that the actual content of all the heavy metals in the soil is over their original background level,with a moderate variance index.According to heterogeneity model and related parameter,Cd,Pb have the strongest spatial correlation,while others ... |
