主要通过遥感（Rs）手段获取研究所需数据，采用地理信息系统（GIS）空间建模和空间分析方法，以衡阳盆地为例，构建提取水资源系统人为脆弱性变化信息的数学模型，生成水资源系统人为脆弱性变化图层，分析近20年来衡阳盆地水资源系统人为脆弱性变化的时空特征，并进行趋势分析。结果表明：①近20年来，衡阳盆地人为水资源系统整体上变得更为脆弱，34．41％的区域人为脆弱性指数明显增大，脆弱性指数变小的区域少；②脆弱性指数变化区域分异明显，衡东县、衡南县的东部和祁东县的西部以基本不变化和略微增大为主。祁东县的东南角和耒阳市的东部以增大类型为主，减小类型则主要集中在常宁市；③脆...

Collecting required data of the research through RS, constructing the spatial model and conducting the spatial analysis with GIS, this paper constructed the mathematical model to extract the changing information and generated the changing layers about artificial vulnerability of water resource system in Hengyang, analyzed the spatial - temporal characteristics of artificial vulnerability of water resources system and the changing trend during recent two decades in this area. After the carefully researched and detailed analysis, this paper drew ...
