Based on the text of the survey farms,environmental profile,choosing the GB 15618-1995 national standard assessment method,fuzzy comprehensive evaluation method,the single factor index and the integrated pollution index method Nemero home field to evaluate the home field soil heavy metal pollution.At the same time,the correlation between plant and soil heavy metal content was analyzed.The results showed that Wenjiachang soil Cd,Zn pollution was serious,Hg pollution was more serious in the Fe content of the soil much more than Background Values of Chinese Soil,also belongs to serious pollution,Mn,Cu,Pb,As was light pollution,The pollution of Mn,Cu,Pb and As is lighter.The pollution of heavy metals in soil was serious.%基于对文家场环境概况的调查,选择GB 15618-1995国家标准评价方法、模糊数学综合评价方法、单因子指数及内梅罗综合污染指数方法对文家场土壤重金属污染状况进行了综合评价,同时对植物与土壤中重金属含量的相关性进行了分析.结果表明,文家场土壤Cd、Zn污染严重,Hg污染较为严重,土壤中Fe的含量远远超过中国土壤元素背景值,属于严重污染,Mn、Cu、Pb、As污染较轻.总体上文家场土壤重金属污染属于严重污染级别.
