摘要: 从构建多用途流域分布式水文模型的标准化、模块化需求出发,自主研发了基于海量数字化信息和气象水文监测数据等多源数据融合前处理系统。该系统基于一个流域四级划分框架体系,建立了空间数据与属性数据的动态关联。此外,其实现模型与GPS、GIS、RS系统从流域层次到网格层次的无缝耦合,能快速移用于不同的流域分布式水文模型构建中。该系统应用于长江河口地区分布式和半分布式水文模型的空间信息和拓扑关系构建中,证明其方便性和适应性。

Abstract: Multi-source data fusion pretreatment system which is based on vast digital information, meteorological and hydrological monitoring data and so on is put forward for standardization and modularization needs of multi-purpose distributed hydrological models. The dynamic connection of spatial data and attribute data is created based on a four-level division framework of watershed. Besides, it also achieves seamless connections between GPS, GIS, RS systems and hydrological models from grid level to basin level, and can be quickly applied to different hydrological models. The system is used to build spatial information and topological relationship of distributed and semi-distributed hydrological models in Yangtze estuary, which suggests its convenience and adaptation.
