摘要
结合地理信息系统(GIS)技术和三维仿真图示技术,探讨了基于GIS的河道、蓄滞洪区洪水演进可视化仿真技术原理与方法,分析了洪水演进可视化模型的建立过程,设计出河道、蓄滞洪区洪水演进系统的总体结构及开发模式,并介绍了系统具体功能的实现.本仿真模型在实例中得到了成功的应用,可为防洪减灾决策提供快捷、直观形象的信息支持.
With geographic information system （GIS） and three-dimensional simulation graphics technique, the technical principles and methods of GIS-based flood routing dynamic visual simulation for river, storage and detention basins are discussed in the paper. At the same time, the process of establishment of three-dimensional visual models is analyzed, and the general framework and development pattern of the flood routing system for river,storage and detention basins is designed. In the end the realization of functions of the system is also introduced in details. The application of the simulation system in a practical case shows the effectiveness of the presented technique, and it can provide quick and intuitionist dynamic information support for flood control decision-making.
