地球信息科学方法在分布式水文模型中的应用研究综述

Research review on the applications of geo-information science in the distributed hydrological model

研究变化环境下的水文水资源,需要水文模型的支持.流域水文模拟已从集总式模型发展到分布式模型.地球信息科学的发展为流域水文模拟提供了新的手段和方法,促进了水文模型的发展.首先介绍了流域水文模型的研究进展,然后对地球信息科学方法在分布式水文模型中的应用进行了综述.

Hydrological model is needed for the research on the hydrology and water resources under the changing condition. In the lumped hydrological model the hydrological variables and parameters are assumed as uniform in the whole basin. Due to the development of geo-information science, which can deal with variety of hydrological variables and parameters, the distributed hydrological model have been getting more attention and development. This paper reviews the studies on hydrological model and the method ofgeo-information science for the distributed hydrological model.
