海面—地面升降综合影响模拟和评估系统研究

Architecture Design of the System of Simulation and Appraisals of the Compositive Influence of Sea Level-Land Surface's Up and Down Changing

采用GIS工程理论的研究方法并结合实际的工作经验,分析了海面—地面升降综合影响模拟和评估系统的设计目标、设计原则、系统的功能及实施情况,并给出系统的数据库、模型库和系统网络架构的解决方案及系统的功能体系结构,通过采用动态模型库、组件技术和C/S与B/S相结合的组网方案,保证了系统在横向(用户)和纵向(功能、数据)可扩充的特性,是GIS技术应用与海面—地面系统变化研究的一个新的探索,采用WebGIS技术保证了模拟和评价结果能够快速为沿海区域发展、工程规划和风暴潮、盐水入侵,以及沿海、沿江、沿湖低地的洪、涝等灾害的防治提供一定的决策支持。

Adopting the research methods of GIS project theory and combining with the practical work experience,this paper analyzes the system-designed target,design rules and system function,and reaches the scheme and functional structure of system database,model Base and network structure. By using the technique of dynamic model base,COM and the scheme combining C/S with B/S,the system is ensured the transverse (users) and longitudinal(functions) expansion,which is a new way to explore GIS application and the Sea Level-Land surface System,The result of simulation and appraisals will give supports of coastal area development,projects programming and the prevention of storm tide disaster,seawater inrush,coastal flood etc.
