【 摘 要 】

A new comprehensive evaluation method of heavy metal pollution based on the fuzzy mathematics was constructed. The results showed that mean concentrations of the heavy metals in the contaminated soils decreased in the order of Zn > Pb > Cd>Cu > As>Ni>Cr. Leaching experiment results showed that concentration of heavy metal in leaching agent of soil is not proportional to the content of heavy metal in soil. Through fuzzy comprehensive evaluation, the solid soil environmental quality grade was heavy pollution and leaching liquid water quality standards was grade V.
