| 摘 要： | 对南京市八卦洲蔬菜基地土壤中的铅、铬、铜和镉进行测定分析,利用不同的评价标准来评价其环境质量状况,同时借助GIS软件研究了污染指数的空间分布状况,并解析了其重金属污染的来源.结果表明,以自然背景值为评价标准,则蔬菜地土壤中的重金属都超过污染指标,其中镉为首要污染因子;以国标二级为评价标准,则除镉以外的三种重金属的单项污染指数值全都小于1,但其综合污染指数迭1.50,总体上属轻污染状况.南京化工因区、南京长江二桥和各种农业生产活动等可能是主要污染源.

| Abstract: | The contents of heavy metals(Pb,Cr,Cu and Cd) in vegetable soils in Baguazhou Town,Nanjing were investigated to evaluate soil environmental pollution of heavy metals by using different evaluation standards of heavy metal pollution for comparison,furthermore,the spatial distribution of pollution index was analyzed with the aid of geographical information system(GIS) technology and potential sources of heavy metal pollutants in vegetable soils were also elucidated.The results showed that the soils were pollut... |
