【摘要】 洪水风险图作为重要的防洪非工程措施之一，在制定防洪规划、建设防洪工程、辅助防洪调度决策、部署防汛抢险方案以及规范国土的开发与管理、加强水行政主管部门依法行政、增强全民的防洪减灾意识等方面有着非常重要的意义。与我国的防洪工程建设相比，我国的洪水风险图研究相对滞后，随着我国防洪理念由“控制洪水”向“洪水管理”的转变，开展区域洪水风险图研究愈来愈显示出其重要性和紧迫性。本文基于GIS技术对上游有控制性防洪水库工程、下游连接人工河道堤防、两岸具有重要保护对象(如城市)的典型防洪系统洪水风险图进行了研究。典型防洪系统的洪水风险图研究包括水库库区、溃坝、河道、堤防及城市五部分。本文分析了水文学方法、洪水演进水力学数学模型等两种洪水淹没分析方法的基本原理及在不同区域的适用性，并采用基于宽顶堰流的溃坝模型和概化溃堤模型进行了坝堤溃决分析，提出了基于空间数据属性表字段进行渲染的洪水风险图绘制方案，论述了经验公式估算法及分类资产洪灾损失评估模型两种洪灾损失计算方法，并将GIS技术应用于洪水风险图信息管理系统开发，采用ArcObjects组件技术实现了洪水风险图的自动绘制、洪水风险图的多种形式输出、洪水演进动态演示和洪水风险图信息便捷查询。本文将洪水淹没分析方法、洪水风险图绘制技术、洪灾损失评估方法和基于GIS的洪水风险图信息管理系统开发技术应用于江苏省洪水风险图试点区域——石梁河水库、新沭河、连云港市城区洪水风险图研究，建立了集洪水风险图分析、绘制、输出及洪灾损失评估功能为一体的洪水风险图信息管理系统，为区域开展防洪减灾工作提供了决策支持。更多还原

【Abstract】 As one of the important non-structure measures for flood control, flood risk map is of concernful meaning on instituting flood control planning, constructuring flood control projects, support flood control operation, arranging flood defence and rushing to deal with an emergency, standardizing the expoitation and management of ground, strengthening the law foundation of water administration and enhancing the civil consciousness of flood control and flood disaster mitigation. The research on flood risk map of our country is more lagged when compared to the construction of flood control projects. Along with the change of flood control theory in our country from controlling flood to flood management, the research on regional flood risk map is more and more important and pressing. The flood risk map of an typical flood control system which consists of reservoir on the upper reaches, riverway and dike on the downstream reaches and important regions protected along with rivers (such as cities), is studied in this thesis based on GIS technology.The study on flood risk map of typical flood control system includes reservoir region, dam break, riverway, dike break and city flood risk map. The basic theory and application in different regions of two flood inundation analysis methods, hydrological method and hydraulic model for flood routing, are analyzed in this thesis. Dam break model based on broad-crested weir flow and synthetic dike break model are used to analyze the process of dam break and dike break. Flood risk mapping scheme according to fields of attribute table of spatial data is put forward. Empirical formula and flood loss assessment model for classified assets are given. GIS technology is applied to the development of flood risk map information management system. The ArcObjects is used to actualize the automatic mapping of flood risk map, multi-form output of flood risk map, dynamic demonstration of flood routing and convenient query of flood risk information.The flood inundation analysis methods, flood risk mapping technique, flood loss assessment methods and the development technique of flood risk map information management system are applied to the experimental region of Jiangsu province, i.e. Shilianghe reservoir, Xinshu river and Lianyungang city. A flood risk map information management system being of the functions including flood risk map analysis, mapping, output and flood loss assessment, is developed, which provides assistant support for flood control and disaster mitigation decision making of the area.更多还原
