摘　　要：地下水防污性能评价是保护地下水资源的有效工具.国内外专家进行了许多研究,提出了多种地下水防污性能评价模型,最常用的是DRASTIC模型.但这些模型主要适用于孔隙水地区,对岩溶地区的适应性差.为了研究岩溶地区地下水防污性能,欧洲专家提出了欧洲方法(Europeanapproach).在欧洲方法这个概念模型的基础上,学者提出了多种岩溶地区地下水防污性能评价方法,如PI方法、VULK方法、LEA方法、COP方法和Time-Input方法.本文主要对PI方法进行了较详细的介绍,并指出应用该方法时应注意的问题.Groundwater vulnerability assessment is a useful tool for groundwater resource protection. Many studies have been done and several vulnerability assessment models have been carried out for assessing groundwater vulnerability worldwide, such as the widely used DRASTIC model. These assessment models are the same with the loose Quaternary deposits but are not the same with karst area. In order to assessing groundwater vulnerability of karst area, European approach have been brought forward. It is an conceptual model of ＂origin-pathway-target＂. Several vulnerability assessments for karst area have been carried out basing on the conceptual model. Such as PI Method, VULK Method, LEA Method, COP Method 和 Time-Input Method.In this paper, PI Method has been detalledly introduced and point out some attentive problem.
