摘要
近几年,随着计算机、地理信息系统GIS和遥感技术的发展,分布式水文模型得到了迅速发展。首先介绍了地理信息系统在分布式水循环模型的应用,探讨了地理信息系统与分布式水文模型的 4种集成模式;然后应用松散耦合结构开发了基于GIS的 水循环机理 系统理论相耦合的时变增益分布式水文模型"系统,并在甘肃省内板桥流域进行了实例验证,获得了良好的模拟效果。
In recent years, alona with the development of computer science, Geographic information systems (GIS) and Remote sensing (RS) technology, the study of Distributed Hydrological Model (DHM) has also made quick progress. First the applications of GIS in DHM were introduced, and four different approaches widely used to integrate GIS with DHM were addressed. Based on the analysis of the advantages and disadvantages of these approaches, the author developed the GIS-based Distributed Time Variant Gain Model (DTVGM) system by coupling mechanism of water cycle with system theory, which integrate GIS and DHM by means of loosing coupling. The system was proved valid and efficient by the case study in Gansu province Banqiao basin.
