摘　　要： 通过对上海化学工业区土壤环境背景值的调查研究 ,得出了该地区土壤元素的环境背景值和分布类型 ,并与其它地区的土壤背景值进行比较 ,指出了其异同点。元素地球化学特征研究表明 ,Cd、Hg、Zn在化工区土壤中表现为高背景分布 ,As、Hg、Pb、Ni在新建围垦区存在条带状高含量区 ;在纵向剖面上 ,As、Cr、Zn等元素在土壤剖面中上下含量变化差异较小 ,Hg表现为表层富集 ,Mn在土壤剖面近地下水层处富集。这对该地区今后环境保护、监测评价和环保对策制定提供了科学依据。 Based on the investigation of soil environment baseline in Shanghai Chemical Industrial Park,we obtained the element baselines of the soil and distribution types in the Park,and compared with other areas to find out the similarity and difference.The results showed that the contents of Cd,Hg and Zn in this area were higher,and As,Hg,Pb and Ni appeared a strip of high level in newly-built reclamation land.There were little difference in the contents of As,Cr and Zn in vertical profile,while Hg was accumulated in topsoil,and Mn was accumulated in the near ground water zone.The research will provide scientific support for environmental protection,monitoring assessment and countermeasures in the future.
