地下水脆弱性评价是保护地下水资源的重要手段，本文根据扬泰地区浅层地下水的水文地质条件，对DRASTIC模型进行了修改。选取地下水位埋深、大气降水入渗净补给量、含水层介质、含水层厚度、地形坡度、包气带介质影响、含水层富水性7个因子作为评价因子，利用层次分析法确定各因子的权重值，建立了符合扬泰地区浅层地下水脆弱性评价模型；利用ArcGIS10．0软件的空间叠加分析功能，编制了扬泰地区浅层地下水脆弱性评价等级图，评价结果与该地区实际水文地质条件基本吻合，对扬泰地区的地下水资源保护和区域规划具有一定的参考价值。

The groundwater vulnerability assessment is an important means for the protection of groundwater resources .Based on the hydrogeological conditions of Yang -Tai Area, this paper has rectified the DRASTIC model , selecting depth of groundwater , recharge of rainfall infiltration , aquifer media , aquifer thickness , topography , impact of the vadose zone media and water -rich of aquifers sev-en factors as the evaluation factor , using AHP to determine the weight value of each factor , and established shallow groundwater vul-nerability assessment model for Yang -Tai area .Finally the shallow groundwater vulnerability assessment level diagram has been com -pleted through spatial overlay analysis using ArcGIS 10.0 software.The assessment results are in accordance with the actual hydrogeo-logical conditions of this area , and has a useful reference value for groundwater protection and regional planning in Yang -Tai area.
