摘要
文章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,采用数字网格技术,以流域水量变化对地表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下垫面和气候变化下流域水量响应过程的一般方法,并以黄河河源区为实例进行验证。
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.
