| 摘 要： | 洪水可以补充湿地水源,但是如果利用不当,也会造成危害。因此将VR(虚拟现实)技术应用于扎龙湿地的洪水管理对于湿地的保护非常重要。使用VRML(虚拟现实建模语言)构建了湿地三维地形场景,采用水力学模型计算了扎龙湿地的洪水淹没数据,通过JavaApplet实现了基于网络的三维漫游、洪水信息查询、洪水淹没仿真等功能,建立了交互三维可视化仿真系统。结果表明,该系统可以取得较好的扎龙湿地三维显示效果,较准确地模拟洪水演进过程,对于湿地保护、湿地洪水管理与远程决策有着重要的意义。

| Abstract: | Flood is a source of wetland.But it will do a lot of harm for wetland if the management of it is absent.It is important to use the VR(Visual Reality) technology for managing flood and protecting Zhalong Wetland.First the 3D terrain scene is established by VRML(Visual Reality Modeling Language).Then based on the data which are calculated through the hydraulics model,construct a simulation system with JavaApplet.The System is composed of the 3D cruising,the flood information inquiring,and the flood routing simulation.The system can display the physiognomy of Zhalong Wetland and simulate the flood routing actually.The work is meaningful for the protection of Zhalong Wetland and the flood forecast. |
