摘　　要：为了解上海市某重点行业企业地块地下水重金属的污染程度,采用了内梅罗指数法及反距离加权插值法(IDW)两种方法进行分析。结果发现,内梅罗指数法及反距离加权插值法(IDW)的分析结果均是可信的,都反映厂区内废水处理区的地下水重金属污染程度较高。相较于内梅罗指数法,反距离加权插值法(IDW)更能反映调查场地内地下水质量的空间分布。In order to know the pollution degree of heavy metals in the ground water of a key industry enterprise in Shanghai,two methods,i.e.Nemerow Index Method and inverse distance weighted interpolation method(IDW),were used to analyze the pollution degree of heavy metals.The results show that both the nemerow index method and inverse distance weighted interpolation method(IDW)are reliable,and both indicate that the heavy metal pollution of groundwater in the wastewater treatment area is high.Compared with nemerow index method,inverse distance weighted interpolation(IDW)method can better reflect the spatial distribution of groundwater quality in the site.
