【摘要】 南海是我国海洋资源最丰富的海区，而且对于国防安全具有非常重要的战略意义。海洋的合理开发利用、海域的合理使用、海洋环境的保护、海洋权益的维护和海洋灾害的预防等都必须建立在海洋信息的综合管理与辅助决策支持之上。目前，海洋地理信息系统在国内外无论在理论上还是实践上尚处于起步研究阶段。本文对南海地理信息系统的建设作了初步的探索。 本文以南海的各种环境和资源要素作为研究对象，从软件工程的指导思想出发，以组件式GIS软件MapX4.0和面向对象的可视化编程工具Visual Basic6.0和Matlab5.3构架的技术体系为基础，开发了一套方便、实用的南海地理信息系统。 本文主要对系统建设的总体框架设计、数据组织与管理、信息分类与编码、数据库建设、应用模型的开发以及GIS平台与应用模型的集成等方面进行了初步研究。此外，还着重对本系统实现的一些关键性技术，如多源地学信息融合技术、三维可视化技术、任意地形剖面的绘制、动画的制作等方面分别作了较为深入的探讨。 总之，本研究既有理论意义，又有实际价值，对于南海地理信息系统的建设在理论和方法上都是一种有益的探索与尝试。更多还原

【Abstract】 South China Sea is the most abundant ocean that contains plenty of marine resources and has strategic significance for the national defence. The reasonable utilization of the marine resources, the effective utilization of the maritime space and the marine ecological environmental protection, the keep of ocean rights are all rely on the general management of marine information. As to now, the research of Marine Geographical Information System is still on the preliminary stage inside and outside. There are still many problems to improve both in theory and methods. This paper presents the construction of South China Sea information system.This paper studies with emphasis the environmental and resource factors directed by the thinking of software engineering, using the component GIS software MapX4.0 and the object oriented programming tools Visual Basic6.0 together with MatlabS.3 as tools to develop the SCSGIS.This paper mainly illustrates the design of general frame and the data management and organization, information classification and coding, database construction, the development of the applied models and the integration of the GIS and applied models. Some of the key technologies of SCSGIS, such as 3D visual technology, the protraction of the topographical profile and the fusion of multi-geo-data are analyzed.In a word, the research does some useful and meaningful try in SCSGIS both in theory and technology and has some creativity of analysis of SCS studies on modern GIS technology (especially incomponents technology) which will help to promote the development of the theory and technique of MGIS.更多还原
