摘　　要：利用遥感和GIS技术进行浅层地下水富集性快速评估,提取了与地下水赋存相关的断裂密度、地质类型、地形坡度和河流密度作为地下水赋存的影响因子,提取了土壤热惯量和植被覆盖度作为地下水赋存的指示因子,并利用层次分析法建立了浅层地下水富集性评估模型,对朝阳地区地下水富集性进行了评估。实地验证结果表明地下水富集性评估结果与实地调查出水量之间呈指数相关关系,说明利用该方法能够对研究区地下水富集性进行准确评估。Remote sensing （RS） and geographic information systems （GIS） were used to estimate the shallow groundwater potentiality. The geology, lineament density, recharge and slope were chosen as factors affecting groundwater formation. The thermal inertia and vegetation canopy were taken as indicators of the groundwater occurrence. A model based on the Analytic Hierarchy Process （AHP） techniques was built to understandthe i connection between the information and the groundwater potentiality, and it was used to map the groundwater potentiality of the study area. The estimated potentiality index was compared with the field-measured well yield data. The results suggest that the potentiality index and the field measured data are exponentially related, indicating that this method is suitable to groundwater potentiality estimation.
