AHP在地下水防污性能评价中的应用-以江苏浅层孔隙地下水为例

地下水的防污性能评价是地下水环保工作的基础，其结果能为地下水环境保护、饮水安全保障体系建设等提供科学依据。针对传统DRASTIC评价模型存在的不足，结合江苏省浅层孔隙含水层的水文地质条件。提出基于层次分析法（AHP）的DRAVT防污性能评价模型，利用GIS空间分析功能进行地下水防污性能评价．该模型的评价结果客观科学，能有效的为规划部门及地下水资源管理部门服务。

Application of Analytic Hierarchy Process （AHP） in Groundwater Vulnerability Assessment-A Case Study of Shallow Groundwater in Jiangsu

Groundwater vulnerability assessment, results of which provide scientific basis for safe potable water protection system construction, has become the basis for groundwater protection. To cover the shortage of traditional DRASTIC assess- ment model and improve data accuracy, the paper establishes a new DRAVT groundwater vulnerability assessment model with the consideration of real hydro - geological conditions of shallow groundwater in Jiangsu. With GIS technology and Analytic Hi- erarchy Process （AHP） technology, DRAVT can assess groundwater vulnerability objectively and scientifically and give groundwater management departments much assistance.
