黑河流域虚拟仿真系统建设

Construction of virtual simulation system for Heihe River Basin

结合黑河流域的特点,以数字高程模型和二维GIS数据为基础,利用VRMAP三维开发平台,采用三层架构体系,在黑河水量调度管理信息系统中构建了黑河流域虚拟仿真系统.系统采用GIS图层控制方式管理场景内容,以灌区和干渠为表现重点,在全流域范围内进行了水量调度中最重要的实时河道水量演进模拟,进一步促进了虚拟现实技术在水利工程中的应用,丰富了"数字黑河"的内容.

In combination with the characteristics of the Heihe River Basin, a virtual simulation system was constructed for the information system of water volume operation and management of the Heihe River Basin by use of the 3-D VRMAP software and three-layer system based on the digital elevation model and 2-D GIS data. With irrigation regions and main channels taken as main objectives to be reflected, the system controlled the scenes with the GIS multi-layer structure. Moreover, a real-time flood routing simulation, which is most important to water volume operation, was performed for the whole river basin. The present work promotes the application of virtual reality to hydraulic projects and enriches the content of 'digital Heihe River'.
