摘要
Abstract
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.关键词
