摘要
对城市洪涝灾害风险的概念和内涵进行系统梳理,论述历史灾情统计法、遥感和GIS耦合法、指标体系法和情景模拟法等4种洪涝灾害风险分析方法的应用现状、适用范围和优缺点,着重就应用较为广泛的风险评估指标体系法进行论述,介绍指标体系构建和指标权重确定方法;论述了可应用于城市洪涝灾害风险等级区划的相等间隔法、分位数法、均值标准差法、自然间断法和隶属度函数法等方法,旨在为洪涝风险等级区划提供参考。
The concept and connotation of urban flood disaster risk are analyzed systematically,and it is discussed that the application situation,scope of application as well as the advantages and disadvantages of four flood disaster risk analysis methods including historical disaster statistics,remote sensing and GIS coupling,index system method and scenario simulation method.The index system method which is widely used for risk assessment is mainly discussed and the method of index system construction and index weight determination are introduced.The equal interval method,quantile method,mean standard deviation method,natural interruption method and membership function method that can be applied in the urban flood disaster risk level zoning are expounded,providing reference for the flood risk level zoning.
