摘要

摘要: 海底地形是海洋地质学、海洋地球物理学、物理海洋学和海洋生物学等研究的基础资料,是影响海洋要素分布的重要因素之一。可视化是地形数据解译的关键,它为揭示海底地形与其他海洋要素之间所蕴含的关系和规律提供了独到的方法。基于可视化工具Vertical Mapper,在MapInfo Professional中对南海海底地形信息进行了渲染图与三维可视化实现,并对地形进行了剖面分析,进而将可视化的南海海底地形信息与表层沉积物类型、流场等其他海洋要素信息进行叠加分析,由此探讨了表层沉积物类型的分布与地形、海洋动力条件等的空间相关性,说明海底地形的可视化对于海洋地质现象的解释具有重要的意义。

Abstract: Submarine landform is the basic information of marine geology,marine geophysics,oceanography and marine biology research and is one of the important factors which affect the distribution of marine constituents.Visualization is the key to understanding the topographical data and provides a special way of revealing the relationship and laws between submarine landform and other marine factors.The visualization of the topographical information,including rendering map and three-dimensional visualization,and the profile analysis of South China Sea were realized based on Vertical Mapper which was embedded into the desktop Geographic Information System software MapInfo Professional in this paper.Overlay of submarine landform information and other marine constituents such as the surface layer sediment types and ocean current were analyzed.And the spatial correlation of the distribution of surface layer sediment types and visualized submarine landform and ocean current were discussed based on overlay analysis,which suggests that the visualization of submarine landform information has significant meanings to interpret the marine geological phenomena.
