摘　　要：在DRASTIC指标的基础上,运用层次分析法构建了云南省曲靖盆地地下水脆弱性指标体系,并采用多级二层模糊评价方法进行脆弱性评价。结果表明:曲靖盆地地下水脆弱性分区为四级,西部基岩地下水和孔隙水脆弱性高,东部的孔隙水及少量岩溶水处于脆弱性中等。评价结果有利于地下水环境的保护。This paper built a two - story evaluation index system by using analytical hierarchy process basis on the DRASTIC, and used two-story fuzzy evaluation to carry out groundwater vulnerability assessment in Qujing basin. The results show that Qujing basin groundwater vulnerability is separated four classes, the vulnerability of western bedrock groundwater and pore-water groundwater is high, eastern porewater and part of karst water is middle. The evaluation results are conducive to the protection of groundwater environment.
