摘　　要：为了实现贵州省毕节地段地下水系统脆弱性评价的直观展示,选取含水层埋深、含水层补给、含水层介质类型、土壤介质类型、坡度、包气带厚度和渗透系数七项评价因子,采用DRASTIC模型建立了地下水系统脆弱性评价模型,通过模糊层次分析法(FAHP)确定了评价因子的权重,并基于ArcGIS软件对毕节地段地下水资源的各项数据指标进行了矢量化,实现了毕节地段地下水脆弱性等级划分的直观性分布图。评价结果表明,该区域地下水脆弱性较高且分布不均。In order to realize the system of groundwater vulnerability evaluation of direct distribution in Bijie area, Guizhou province, seven evaluation factors as aquifer buried depth, the types of aquifer recharge, aquifer media, soil media type, slope, the thickness of the vadose zone and the permeability coefficient were selected. Through fuzzy analytic hierarchy process （ FAHP） to determine the weights of evaluation factors, and based on ArcGIS software to vector quantization data index of groundwater resource in Bijie area, realized the groundwater vulnerability distribution of visual hierarchy. The evaluation results show that the regional groundwater vulnerability is high and the distribution is uneven.
