摘　　要：利用分布式水文模拟方案构建范式,通过流域解构和解析进行拓扑重构,即考虑流域下垫面空间变异性,将流域离散成各产汇流分区,并与预报站点结合解析出各水文模拟分区集合,以建立分区间的拓扑关系。根据不同的需求构建不同的模拟方案,在ArcGIS软件平台上以东江流域为例进行历史洪水仿真模拟。结果验证此模拟方案具有优越性和灵活性,该法具有一定的适用性和参考价值。Based on the construction scheme of distributed hydrologic simulation program, considering the spatial variation properties of the basin underlying surface, basin is divided into zone of runoff yield and concentration with the topology reconstruction of basin, which is handled by deconstruction and analysis method. The set of hydrologic simulation zone is analyzed by the forecasting site and it is used to establish the topology relationship of zones. Various simulation programs have been constructed by the different demands. Taking the Dongjiang Basin for an example, historical flood is simulated by using the ArcGIS software platform. The result shows that the simulation program is quite superior and flexible.
