摘　　要：在分析DRASTIC方法的基础上,结合前人研究成果,运用层次分析法构建了二层评价指标体系,并结合多层次模糊评价理论,建立了基于层次分析的DRASTIC二层模糊评价模型,并将该模型应用到曲靖盆地地下水脆弱性评价中。结果表明,该模型评价灵敏度高,更能反映地下水脆弱性的空间连续性,且该模型计算方法较简便,进一步丰富了地下水脆弱性的评价方法。Based on analyzing the DRASTIC method incorporated with previous achievement, using analytical hierarchy process, a two-stored evaluation index system is built in this paper. A two-story fuzzy evaluation model is established based hierarchy analysis combined with multi-layer fuzzy evaluation theory. This model is applied to assess the groundwater vulnerability in Qujing basin, and the results show that the model is sensitive enough to evaluate and is simple for calculation. This method enriches the groundwater vulnerability assessment method.
