摘要(Abstract)：

洪水的形成和演进是一项复杂的时空过程，如何快速理解并直观呈现洪水的产生、汇集、演进和调度过程，是辅助形成科学综合决策的基础。以态势推演等理论为基础，结合洪水的特征和影响因素建立了洪水时空态势过程模型，提出了3DGIS场景下的洪水时空态势可视化与动态推演方法，搭建了洪水时空态势调度模拟程序框架。以2020年长江流域洪水为例，结合洪水过程的调度计算结果，运用该程序框架开展多种时空态势的分析、推演和可视化应用，在三维虚拟场景中直观展现洪水过程。结果表明：基于3DGIS的洪水时空态势推演与调度模拟方法能清晰呈现洪水的时空态势，并辅助理解洪水的演进趋势和风险，直观再现洪水的时空全过程，为防洪调度会商提供辅助支撑。
