发布时间：2018-09-11 09:45
【摘要】：胶东半岛由于其独特的地理位置，海水入侵风险给当地居民带来的灾害最为严重。国内外专家学者就海水入侵分析做出了深入的研究，包括利用计算机技术、地理信息系统技术、网络技术、三维可视化技术等来精确地模拟入侵过程。海水淹没出现后必然会造成损失，，在这种情况下利用非工程手段进行减灾备受重视，因此进行海水入侵风险评价系统的研究具有重要的理论意义和现实价值。本文从建立三维可视化海水入侵分析、评价功能结构与模型进行研究设计，运用了地理信息系统技术、计算机编程技术、三维可视化建模技术、数据库构建技术进行整合运用，开发了实现海水入侵分析与灾情风险评价信息为一体的信息化系统，从而为胶东半岛地区防洪减灾部门提供及时、准确、科学的风险评价信息，为当地的防洪减灾工作提供支持。 研究就海水淹没理论，分有源淹没与无源淹没两种算法进行海水入侵模拟。在WebGIS的基础上，采用Skyline开发平台构建三维地形模型、ArcGISAPI forJavascript和ArcGIS Server Rest实现地图的可视化，构建基于WebGIS的海水入侵三维可视化的风险评价系统，既实现了海水淹没的模拟，又达到了三维可视化的效果。本系统的开发和使用证明了WebGIS技术与三维可视化技术相结合，能够实现海水入侵过程、入侵的网络三维可视化和相关的淹没分析、风险评价。研究成果对胶东半岛地区蓝色经济发展防滑减灾提供科学依据和技术支持，有着重要的理论意义。
[Abstract]:Because of its unique geographical location, the risk of seawater invasion is the most serious disaster to local residents. Experts and scholars at home and abroad have made in-depth research on seawater intrusion analysis, including the use of computer technology, geographic information system technology, network technology, three-dimensional visualization technology to accurately simulate the invasion process. Sea water inundation is bound to cause losses. In this case, the use of non-engineering means for disaster reduction has attracted much attention. Therefore, the study of seawater intrusion risk assessment system has important theoretical significance and practical value. In this paper, 3D visualization seawater intrusion analysis, evaluation function structure and model are studied and designed, GIS technology, computer programming technology, 3D visual modeling technology, database construction technology are integrated and applied. In order to provide timely, accurate and scientific risk assessment information for flood control and disaster reduction departments in Jiaodong Peninsula, an information system is developed to realize the integration of seawater intrusion analysis and disaster risk assessment information. To provide support for local flood control and disaster reduction. Based on the theory of seawater inundation, the seawater intrusion simulation is carried out by two algorithms, active submergence and passive submergence. On the basis of WebGIS, the 3D terrain model ArcGISAPI forJavascript and ArcGIS Server Rest are built on the Skyline development platform to realize the visualization of the map, and the risk evaluation system of 3D visualization of seawater intrusion based on WebGIS is constructed, which realizes the simulation of seawater inundation. It also achieves the effect of three-dimensional visualization. The development and application of this system has proved that the combination of WebGIS technology and 3D visualization technology can realize the process of seawater intrusion, the network 3D visualization of intrusion, the related submergence analysis, and the risk evaluation. The research results provide scientific basis and technical support for the development of blue economy in Jiaodong Peninsula, and have important theoretical significance.
