摘　　要： 针对海平面上升后淹没范围的动态模拟问题,研究了面向大场景三维可视化的数据组织与调度、顾及球面四元三角网(Quaternary Triangular Mesh,QTM)邻近关系的淹没范围模拟等关键技术问题;应用Visual C#3.0开发语言和Microsoft Direct X 9三维图形开发包从底层设计开发了基于球面QTM的海平面上升淹没动态模拟系统,介绍了系统的总体架构和主要功能,以天津市滨海新区为试验区域,对给定上升水位的淹没范围进行动态模拟。实验结果表明:该系统可以为海平面上升后沿海区域的淹没灾害预警提供有效的支持。 Focused on the dynamic simulation of submerged area after the rise of sea level, key technical issues were discussed, such as data organization and scheduling in large-scale 3D scene, submerged area dynamic simulation based on the adjacent relations of QTM(Quaternary Triangular Mesh) grids. A submerged simulation system based on QTM was designed and developed using Visual C#3.0 programing language and Microsoft Direct X 9 graphic interface, and the overall structure and main function of the system were introduced in detail. Tianjin Binhai New Area was selected as study area for submerged area dynamic simulation under different sea levels. Results show that this system can provide efficient support for flood disaster warning of coastal area after the rise of sea level.
