基于ArcGIS的廊坊地区洪涝灾害风险评估及洪水淹没分析
Risk assessment and inundation analysis of flood in Langfang region based on ArcGIS
摘要
Abstract
Based on ArcGIS platform,this study extracts the high-precision DEM data,selects the factors of flood disaster risk assessment index system,and uses the methods of flood disaster risk assessment,analytic hierarchy process(AHP),weighted comprehensive evaluation as well as ArcGIS spatial analysis module to analyze four composite factors of risk,exposure,vulnerability and disaster prevention and mitigation capacity.Besides,the risk assessment and zoning of flood disasters in the counties and districts of Langfang City are conducted in terms of natural disasters and socioeconomic factors.The results show that the flood disaster comprehensive risk in the southern area is greater than that in the northern area of the city.The rapid extraction of flood inundation area and water volume information,and analysis results of flood inundation under natural state in the study area is of great significance for flood disaster assessment,rescue and material allocation,which can also provide scientific basis for flood disaster early warning and prevention.关键词
