【摘要】：城市化进程的加快导致城市热岛效应加剧和城市下垫面条件的巨大变化,一方面诱导和强化了城市强降雨天气,另一方面又因城区可渗透地面的减少致使产流量增加,导致城市内涝问题日益严重,威胁着城市发展和人民生活。采用合理的水文模型和现代先进的WebGIS技术,实现城市雨洪内涝的实时预警,对预防城市洪涝灾害和促进城市经济发展具有重大的意义。本文利用暴雨洪水管理模型和雨量站实测降雨数据,实时计算城市内涝积水信息,并采用Java Web技术,研发B/S架构的系统,调用暴雨洪水管理模型动态链接库,基于WebGIS技术实现城市雨洪内涝的实时预警。主要研究内容如下:(1)基于SWMM的郑州市区内涝积水计算。以郑州市区实际管网数据和下垫面数据为基础,进行郑州市区管网概化、子汇水区划分及属性提取,读取河南省雨量遥测数据库中雨量站实测降雨数据,利用SWMM模型计算郑州市区积水点、积水路段等内涝积水信息,并对SWMM模型进行封装,供系统调用。(2)郑州市区暴雨内涝数据库设计。采用数据库技术,依据三范式原理和暴雨洪水管理模型计算的内在逻辑关系,设计冗余较小、结构合理的郑州市区暴雨内涝数据库,并采用My SQL构建关系型数据库,存储郑州市区暴雨内涝相关数据。利用数据库访问技术,采用JDBC数据访问组件实现系统程序语言对数据库的访问,进而实现系统对数据的增删改查等功能。(3)基于WebGIS的郑州市区暴雨洪水预警功能实现。基于MVC框架,采用WebGIS技术和Java Web技术构建B/S架构系统,调用SWMM.DLL和数据库中实测降雨数据,实现郑州市区暴雨内涝积水信息实时计算,通过Arc GIS Server发布地图服务,利用Arc GIS API for Java Script实现地图服务的访问和城市内涝实时预警功能。
[Abstract]:The acceleration of urbanization leads to the intensification of urban heat island effect and the great change of urban underlying surface conditions. On the one hand, it induces and strengthens the heavy rainfall weather in the city, on the other hand, it increases the yield and discharge due to the decrease of the permeable surface of the urban area. The problem of urban waterlogging is becoming more and more serious, which threatens the development of the city and the life of the people. By adopting reasonable hydrological model and modern advanced WebGIS technology, the real-time early warning of urban rain flood is realized. It is of great significance to prevent urban flood disaster and promote the development of urban economy. In this paper, we use rainstorm flood management model and rainfall data measured by rainfall station to calculate the information of urban waterlogging and water accumulation in real time, and adopt Java Web technology. To develop a system based on B / S architecture, call the rainstorm flood management model dynamic link library, Based on WebGIS technology, the real-time warning of urban rain flood and waterlogging is realized. The main research contents are as follows: 1) based on the calculation of waterlogging water in Zhengzhou urban area based on SWMM. Based on the actual pipe network data and underlying surface data of Zhengzhou urban area, the pipeline network of Zhengzhou urban area is generalized. The sub-catchment area is divided and attribute is extracted, the rainfall data measured by rainfall station in Henan rainfall telemetry database are read, and the waterlogging information of Zhengzhou urban area is calculated by using SWMM model, and the SWMM model is encapsulated. The database design of rainstorm waterlogging in Zhengzhou urban area is designed. The design redundancy is less according to the principle of three normal forms and the inherent logical relation of rainstorm flood management model. The rational structure of the rainstorm waterlogging database in Zhengzhou urban area, and the use of my SQL to construct the relational database to store the relevant data of the rainstorm waterlogging in Zhengzhou urban area. The JDBC data access component is used to realize the database access by the system program language, and the system functions such as adding, deleting, modifying and checking the data, etc.) based on WebGIS, the rainstorm flood warning function of Zhengzhou urban area is realized. Based on the framework of MVC, the function of rainstorm flood warning in Zhengzhou urban area is realized. Using WebGIS technology and Java Web technology to construct the B / S architecture system, calling the actual rainfall data in SWMM.DLL and database, realizing the real-time calculation of flood and waterlogging information in Zhengzhou urban area, and publishing map service through Arc GIS Server. The Arc GIS API for Java Script is used to realize the access of map service and the real-time warning function of urban waterlogging.
