摘要
In this paper,characteristics of content,distribution and variation of seven heavy metals(hydrargyrum,plumbum,cadmium,arsenic,chromium,copper and zinc) were analyzed in the study area.Based on the analyses,the fuzzy mathematical method was used to construct the membership functions and a fuzzy comprehensive evaluation model was established.By using this model,soil samples data collected in 2009 in the study area are calculated.The results show that about 38.36% of the soil in the study area was moderate or severely polluted.
