摘　　要：通过对研究目标的可视化需求分析,对研究区域开展了包括流域三维地形仿真、洪水演进模拟的三维可视化研究,揭示洪水的运动规律.以GIS技术为基础,基于二维浅水方程,采用有限体积法,建立洪水演进数学模型,并将其制成动态链接库,通过编程调用该库实现洪水淹没分析功能,计算出给定水位下的洪水淹没面积和水量;采用面向对象的编程语言C#,结合ArcEngine组件库,开发了黄河东平湖洪水淹没场景三维可视化系统,并成功应用于东平湖蓄滞洪区的洪水计算中.On the basis of objectives and visualization demand, in the combination of the current status of the study area in Dongping Lake, investigation on three-dimensional visualization is carried out, which includes three-dimensional topography simulation and flood routing simulation. With GIS technology, based on two-dimensional shallow water equations, finite volume method is adopted to establish a mathematical model for flood routing, which is made into a dynamic link library, and calculate the flood inundation area and amount of water under the given water level through flood analysis by programming to call the library. Meanwhile, using object-oriented programming language C #, with ArcEngine component library, the establishment of flooding simulation scene system for three-dimensional visualization in Dongping Lake will facilitate users to observe, operate and analyze the phenomena and laws of flood routing, which contributes great theoretical significance to the rational utilization of flooding resources.
