摘　　要：地下水防污性能评价是制定地下水资源保护规划和地下水污染防治措施的重要依据。结合文安县的水文地质条件,考虑人类活动影响因素,对传统DRASTIC模型进行了调整改进。选取地下水埋深、包气带介质等5个因素作为评价因子;采用区间数层次分析法(IAHP)计算各评价因子的权重系数,以克服传统方法设置的固定权重问题。评价结果为该区域的环境规划等提供理论参考和方法依据。The evaluation of groundwater pollution prevention performance is an important basis for the formulation of groundwater resource protection planning and groundwater pollution prevention and control measures.Combined with the hydrogeological conditions of Wen’an County and considering the influence factors of human activities,the traditional DRASTIC model is adjusted and improved.Five factors,such as the groundwater depth and the medium in the aerated zone,were selected as evaluation factors.Interval Number Analytic Hierarchy Process(IAHP) is used to calculate the weight coefficients of each evaluation factor,and the evaluation results can provide theoretical reference and method basis for the environmental planning of this region to overcome the fixed weight problem set by the traditional method.
