Application of Fuzzy Comprehensive Evaluation Method in the Dump's Soil Assessment of Heavy Metal Pollution

摘要

Through the investigation and sampling of open pit coal mine field soil in Haizhou, monitoring results of the five kinds of heavy metals (Cu, Pb, Cd, Mn, Zn) by fuzzy comprehensive evaluation method were evaluated, the soil environmental quality of most samples was graded second level. And analyses the vertical distribution from surface soil to-20cm depth. So the fuzzy comprehensive evaluation method can soil's environmental quality of heavy metal pollution.The results provided a reasonable basis for classified management of heavy metal pollution.
