Abstract:In order to quantitatively research the rainstorm and flood disaster risk and zoning in Chongqing,according to 1961 — 2008 meteorological data in Chongqing,integrating with natural,socio-economic and disaster prevention and reduction factors in each district,based on geography information system,methodology of flood disaster risk index and constructed model of rain and flood disaster risk assessment,the flood disaster risk indexes were calculated and risk zoning maps were worked out for every county of Chongqing by analyzing hazard,sensitivity,vulnerability and emergency response and recovery capability of the counties.The results indicated that the possibility of rainstorm and flood risk was the biggest in Kaixian,Liangping,Hechuang,Beibei,Rongchang,Yongchuan,Yubei and partial area of Tongliang,because the indexes of the expositions and the hazard of these areas were relatively higher.Whereas Nanchuang,Fengdu and partial areas of Shizhu,Qianjiang,Fuling,Qijiang had the least flood risk due to lesser disaster environmentally sensitive indexes and torrential rain frequency.
Keywords:rainstorm and flood disaster  flood disaster risk index  risk zoning  Chongqing
