汀溪水库三维防洪调度管理信息系统研发

水库防洪调度是一个非常复杂的过程。水库防洪调度的信息化主要是借助测量、遥测、遥感(RS)、地理信息系统(G IS)、全球定位系统(GPS)等手段采集基础数据,构建数字化水库防洪数据管理平台和水库虚拟三维环境。在该平台和环境中,以系统软件和数学模型对水库流域的水雨情及洪水的调度方案进行模拟、分析和研究,提供决策支持,从而增强防洪调度决策的科学性和预见性。实践表明,通过RS、GIS技术建立的水库三维防洪调度系统能够为水库管理者提供水库防洪调度方案制定与分析、防洪调度决策等方面的强有力的、科学的辅助支持。本文结合厦门"汀溪水库三维防洪调度系统"的实际研发,探讨了RS和GIS技术在水库防洪调度中的应用。

Research on Applying RS and GIS Technique in Big Reservoir Flood Prevention Control

Since reservoir flood prevention control is very complicated,it is necessary to apply information technique to support flood prevention control decision.Informationization of Big Reservoir Flood Prevention Control mainly includes the following contents:(1) acquiring basal reservoir data or flood data by full-digital photography and measure technique,remote monitoring,remote sensing,geographical information system,GPS,etc;(2) constructing digital reservoir flood prevention control management information system and three-dimensional virtual reservoir environment;(3) simulating and analyzing the scheme of reservoir flood prevention control based on massive history data analysis and scientific calculation according to professional reservoir flood prevention mathematic models;(4) providing flood prevention control suggestions for reservoir supervisor.By acquiring basal reservoir data or flood data by full-digital photography and measurement techniques,remote monitoring,remote sensing,geographical information system,GPS,etc,digital reservoir flood prevention control management information system and three-dimensional virtual reservoir environment could be constructed.And then through simulating and analyzing the scheme of reservoir flood prevention control based on massive historical data analysis and scientific calculation according to professional reservoir flood prevention mathematic models,flood prevention control suggestions could be provided for reservoir supervisor.By introducing the research and software development of "Tingxi Reservoir Flood Prevention Control Management Information System",this thesis gives a detailed explanation about how to apply Remote Sensing and Geographical Information System technique in Big Reservoir Flood Prevention Control.
