摘要
分布式流域水文模型比较客观地描述实际水文过程,但需要强大的数据库支持。这一特点为地理信息系统(G IS)在分布式流域水文模型的研究与应用提供了可能,反过来又推动水文模型的发展。目前,基于G IS的分布式流域水文模型的研究已成为水文学研究的热点。本文总结了分布式流域水文模型的优越性,综述了G IS在分布式流域水文模型中的应用及二者集成方式研究与应用的进展,讨论了当前研究中存在的问题,指出了今后的研究方向。
The watershed-scale distributed hydrological model can describes the process of hydrology rather objective. But it needs the strong support of database. This characteristic should be provided with possibility of research and application of GIS into the watershed-scale distributed hydrological model. Presently the research on the model based on GIS has become a hot pot in hydrology. This paper summarized the advantages of the watershed scale distributed hydrological model and the progress of research and application of GIS to this model, discussed the problem in the present research and pointed out the research direction for the future.
