摘　　要：近年来我国棕(褐)地数量不断增加,棕(褐)地的存在给周边的居民和生态环境带来较大危害;我国土地资源紧缺,对于棕(褐)地区域需要进行再开发利用,而棕(褐)地区域在修复治理前后的污染程度需要进行评价研究,为棕(褐)地区域治理管理工作提供参考。文章主要对研究区的棕(褐)地周边的特征污染物即重金属Cu和Cd带来的污染进行评价,对传统的内梅罗方法存在的缺陷进行改进,应用到棕(褐)地周边重金属污染评价实例研究中,并利用GIS软件对评价结果进行空间表示,并分析污染程度的空间分布。In the recent years,the number of brownfield in China has increased,and the presence of brownfield has brought great harms to the surrounding residents and ecological environment.Because of China′s land resource shortage,the brownfield area needs to be redeveloped.Assessment of the pollution degree in the area of brownfield before and after restoration will provide a reference for the brownfield area management work.In this paper,pollution brought by the characteristic contaminants in the surrounding soils of brownfield such as Cu and Cd was assessed.The traditional Nemoro index method with some defects was modified and applied into the case study of pollution evaluation of heavy metals in the surrounding soils of brownfield.Then,GIS software was used to express the evaluation results,and spatial distribution of the pollution degree was analyzed accordingly.
