摘　　要：海洋因其环境的复杂性和数据的难以获取性,其海洋三维可视化方面的研究多集中在海洋场景和海底地形方面,有关海洋底质的可视化研究有待加强。本文通过建立海洋底质数据库,搭建海底底质可视化的模拟环境;基于水深数据和多波束数据建立基本的三维海底地形,实现多任意等深线的自动生成;依据钻孔数据和地层拖网样品,初步实现海底底质三维可视化。通过系统的集成,建成海底三维可视化模拟系统,为开发海洋资源、发展海洋经济和维护国家海洋权益服务。Because of the complexity of sea＇ s environment and the difficulty to gain data, the sea three-dimensional visual research always concentrates on the sea scene and the seabed terrain aspect, and the related visual research of seabed sediment should be strengthened. Through the establishment of seabed sediment database, the seabed sediment visual simulated environment is built. Based on water depth data and multi-beam data, the basic three-dimensional seabed terrain is established and free isobaths automatic production is realized. And based on the drill hole data and the stratum drag net sample, the seabed sediment three-dimensional visualization is initially realized. Through the effective integration, the 3-D visual simulation system of seabed sediment is constructed, which can develope marine resource, sea economy and maintain country sea rights and interests.
