地理信息系统与水文模型集成研究述评

从地理信息系统与水文模型的集成方式,水文模型计算域的空间离散等方面讨论了GIS与水文模型的集成问题,再从四个方面分析了GIS与水文模型集成存在的问题。由于分布式水文模型对空间数据的需求,又从GIS、RS与水文模型的集成现状与发展讨论了集成研究的目标。

Integration of Geographical Information System Technology and Hydrological Model

The conceptual hydrological model, which doesn't consider the spatial variation of the hydrological variable and parameter, mainly simulates the temporal process of the hydrological phenomenon in the catchment.Due to the increasing capacity of acquiring, archiving, storing, analyzing and visualizing the spatial geographical data, the distributed hydrological model, which considers the spatial variation of hydrological variable and parameter, is trend and focus in the hydrological research in the near future.In the paper the integration of geographical information system (GIS) and hydrological model are in detail discussed in two aspects:one is the integrating method of GIS and hydrological, and the other is the spatial discretion of the computational domain.In the end, the problem and future of integrating GIS, remote sensing and hydrological model are elucidated.
