摘　　要：针对基于二维GIS的城市防汛系统存在的无法全面展示水利设施、地形地势、城市内涝等水利场景的不足,分析三维GIS在城市防汛系统建设中的优势,从总体架构和三维数据底板构建及业务应用等维度进行城市防汛系统的分析、设计、研发,形成一套集空间信息存储展示、防汛信息监测预警、防汛调度管理与规划评估等多功能的三维GIS城市防汛系统。系统从汛前规划方案的科学部署、汛时监测信息的及时预警、汛后应急对策的快速响应全过程辅助防汛工作的进行,有效满足城市防汛需求。实际应用表明:基于三维GIS的城市防汛系统可有效支撑城市防汛工作的开展,提高城市汛情的应对及治理能力,为城市防汛信息化建设提供可靠案例。Aiming at the shortcomings of the current urban flood control information system based on 2D GIS that cannot fully display water conservancy facilities,topography,urban waterlogging and other water conservancy scenarios,the advantages of 3D GIS in urban flood control system construction are analyzed.The urban flood control system is designed and developed from the dimensions of overall architecture,3D digital base construction and business application.A set of multi-functional urban flood control system is formed based on 3D GIS,which integrates spatial information storage and display,flood control information monitoring and early warning,flood control scheduling management and planning evaluation.This system assists the flood control work through the entire process from the scientifi c deployment of pre-flood planning schemes,timely early warning of monitoring information during floods,and rapid response to post-flood emergency countermeasures,which has eff ectively met the needs of urban flood control.The practical application shows that the urban flood control system based on 3D GIS can not only improve the response and governance capabilities of urban flood situations,but also provide a reliable case for urban flood control informatization construction.
