The enrichment index showed that the pollution degree of 11 kinds of soil heavy metals were different. Their order was: Cu>Hg>V >Zn>Ni>Cr>Co>As>Mn>Pb >Cd. The heavy metals in 8 different regions had been counted, which showed that the largest enrichment index of As、Co、Hg、Cu、Ni、Mn were in Dong’e town.
