中文摘要：
以遥感（RemoteSensing）RS、地理信息系统（Geographic Information System）GIS为技术支持,气象数据、遥感数据、基础地理信息数据、社会经济数据为基础数据,构建广西北部湾经济区洪涝灾害风险评估指标体系,采用AHP层次分析法及加权综合法建立洪涝灾害风险评估模型;借助GIS技术,计算广西北部湾经济区洪涝灾害致灾因子危险性、孕灾环境敏感性、承灾体暴露一易损性及综合风险指数,并对广西农业暴雨洪涝灾害进行风险区划,研究结果表明,广西北部湾经济区洪涝灾害风险东高西低,沿海地区普遍偏高.
英文摘要：
Constructing comprehensive evaluation and analysis of flood disaster risk of Guangxi Beibu Gulf is based on science of disaster guided by both theory and method of the flood disaster risk assessment system supported by the technology of RS and GIS ,and its basic data including back-ground data of remote sensing ,meteorological data ,basic geographic information data and socioeco-nomic data .It uses Analytical Hierarchy Process (AHP) and weighted summation method to create the flood disaster risk assessment model .It computes flood hazards ,sensitivity of disaster inducing condition ,vulnerability of exposure disaster bodies and composite risk index with the aid of GIS tech-nology which also divides the risk of agricultural rainstorm floods in Guangxi .The research result in-dicates that the flood disaster risk in Guangxi Beibu Gulf Economic Zone is high in the east and low in the west ,and it is generally higher in coastal areas .
