摘　　要：地下水防污性能评价对地下水污染防治分区划分及浅层地下水保护具有重要的意义。文章结合江苏省宿迁城市规划区水文地质条件,建立基于层次分析法(AHP)的DRIAC防污性能评价模型,通过进行防污性能计算和防污性能分区划分,对研究区地下水防污性能进行了总体评价。研究结果显示:计算得到的研究区防污性能综合指数为1.1~4.57。并根据计算结果,将防污性能分为3级。Ⅰ级(V<3.0),防污性能较好;Ⅱ级(3.0≤V<3.6),防污性能一般;Ⅲ级(V≥3.6),防污性能较差。宿迁城市规划区的Ⅰ级区分布面积约306 km2,占总面积的17.97%;Ⅱ级区分布面积约306 km2,3占总面积的21.4%。Ⅲ级区分布面积约306 km2,占总面积的21.4%。研究成果可为行政主管部门对地下水保护和利用提供科学依据。Groundwater anti-pollutionproperty evaluation on groundwater pollution prevention and control of the zoning and shallow groundwater protection is of great importance to combining urban planning hydrogeological conditions of Jiangsu Suqian,based on the analytic hierarchy process(AHP)of the DRIAC anti-pollutionproperty evaluation model,through the a anti-pollutionproperty calculation and anti-pollutionproperty,of the zoning of groundwater in the study area anti-pollutionproperty evaluation as a whole.The results show that the calculated comprehensive anti-pollution performance index of the study area is 1.1~4.57,and according to the calculated results,the anti-pollution performance is divided into three levels(V<3.0),good anti-pollution performance;Level(3.0≤V<3.6),general anti-pollution performance;Grade(V≥3.6),poor anti-pollution performance.The distribution area of grade I of Suqian urban planning area is about 306 km2,accounting for 17.97%of the total area.The distribution area of level-II areas is about 306 km2,accounting for 21.4%of the total area,and the research results can provide scientific basis for the protection and utilization of groundwater by the competent administrative departments.
