采用GIS/RS的方法，以衡阳盆地为研究对象，构建由年降水量，少雨期干旱指数，坡度指数，土壤蓄水能力指数，植被覆盖指数，土地利用指数，水源可获得性指数和人类活动指数8个具体指标组成的基于GIS/RS方法的水资源脆弱性评价指标体系，对衡阳盆地农村水资源脆弱性进行定量评价。结果表明，衡阳盆地农村水资源系统脆弱度的空间分布总体表现为“南北低、中间高”的分布态势，北部的衡阳县、西部的祁东县和中部的衡南县是全区水资源脆弱性最高区域，而南部的常宁、耒阳和东北的衡东县是全区水资源脆弱性低值区。基于GIS/RS 的水资源脆弱性评价方法与传统研究方法所得结果具有较好的相似性，但是，...

The traditional econometric model is mostly utilized in water resources vulnerability assessment field. In recent years, the author and his research teams have studied the water resources vulnerability problem in Hengyang Basin using the traditional method. In order to explore better water resources vulnerability quanti-tative assessment method, in this article, GIS and RS technology was used to evaluated the vulnerability of wa-ter resources system in Hengyang Basin. Using GIS/RS method, take Hengyang Basin as the research region, construct a water resource vulnerability evaluation index syst...
