摘　　要：在干旱半干旱地区,地下水是主要供水水源之一。目前水体污染、水资源短缺、水生态失衡,导致干旱半干旱地区经济发展与水安全保障的矛盾日益尖锐。以兴平地区渭河南岸为例,利用DRASTIC方法,选取潜水埋深、净补给量、含水层介质类别、土壤介质类别、地形坡度、包气带介质类别以及渗透系数为防污性7项评价因子,构建了潜水防污性评价指标体系,对该地区的潜水防污性进行了分区评价,将兴平地区渭河南岸的潜水防污性分为防污性差和防污性较差两个等级,并绘制了潜水防污性评价分区图,为该地区工农业生产的发展和城市规划提供了科学的依据。In arid and semi - arid region, groundwater is one of the main water sources. The problems of water body pollution, shortage of water resources and unbalance of water ecology have made the paradox between the economy development and water safety more and more sharply. With the Xingping region as an example, by using DRASTIC method to select 7 assessment factors such as groundwater depth, net re- charge, aquifer media, soil media types, terrain slope, media types of the vadose zone, and hydraulic conductivity, the paper set up the index system of vulnerability of phreatic water and evaluated the re- gions vulnerability of phreatic water. The vulnerability of phreatic water in Xingping region is divided into poor and poorer grades. Partition map of vulnerability of phreatic water has been made. The result can provide a scientific basis for the development of regional industrial and agricultural production and urban planning.
