摘　　要：三维可视化技术已在大坝安全监测、水利工程质量检测、水资源配置等领域得到广泛应用。借鉴其它领域的应用成果,利用三维可视化等技术构建了鄱阳湖水利信息三维展示与查询系统,实现了鄱阳湖在不同水位下的三维地形信息展示,再现了鄱阳湖水利信息虚拟场景;此外,还利用Java进行二次开发,构建了鄱阳湖区空间数据库和多媒体数据库,实现了湖区三维场景的直观清晰浏览与展示,以及专题水利热点数据的动态查询和漫游等功能。该系统的建立可方便用户全面了解鄱阳湖区不同水位下淹没区域、自然保护区和风景区的水资源、水生态、水环境和水利工程等水利信息,有助于提高鄱阳湖管理者的科学决策水平。3D visualization technology has been widely used in dam safety monitoring,quality inspection of water conservancy engineering,water resources allocation and other fields.Based on the application results in other fields,the 3D display and query system of water conservancy information in Poyang Lake was constructed by using 3D visualization and other technologies.So 3D terrain information display of Poyang Lake under different water levels was realized,and the virtual scene of water conservancy information in Poyang Lake was reproduced.In addition,the spatial database and multimedia database of Poyang Lake were constructed by using Java for secondary development,and the functions of visual and clear browsing and display of 3D scene in the lake area,as well as dynamic query and roaming of special water conservancy hot spot data were realized.The establishment of this system can facilitate users to fully understand the water resources,water ecology,water environment and water conservancy projects of nature reserves and scenic spots and flooded areas under different water levels in Poyang Lake area,and help to improve the scientific decision-making level of Poyang Lake managers.
