摘要
基于遥感和地理信息系统技术的分布式水文模型是目前水文模拟发展的主要方向。分析了分布式水文模型、遥感和地理信息系统技术在流域径流模拟过程中的结合点,并针对流域径流要素对土地覆被和气候变化响应过程为目的,讨论利用分布式水文模型研究土地覆被和气候变化下径流响应过程的一般方法。
Physical-based distributed hydrological model based on Remote Sensing (RS) and Geographic Information System (GIS) has been the main developing direction for hydrological process simulation. The paper analyzed the conjunction point of physical-based distributed hydrological model, RS and GIS in watershed runoff process simulation. The general method of studying runoff response process under climate and land-cover changes with supporting of RS and GIS was discussed for reflecting the response of watershed rainfall-runoff factors to climate and land-cover changes.
