Based on the basic principles of flood risk,this study took the coastal areas in southeastern Asia(SEA) as the study area.By integrating the indicators including the rainfall,topography,land use,vegetation,river density,population,and the economic strength,the flood risk over the chosen study area was evaluated through both qualitative and quantitative methods.The indicators used were firstly normalized to obtain stan-dardized multi-source raster data by the GIS(Geographic Information System) techniques.The AHP(Analytic Hierarchy Process) technique was then utilized to estimate the weights of those indicators,and used to devel-op a model for risk assessments.The map algebra in GIS was finally employed to generate the flood zoning map over the typical Asian areas.The results show that the high risk regions of flood storm primarily include the southeastern,northeastern,and coastal areas of China,the eastern India near Bangladesh,the eastern Ban-gladesh,and the northeastern Myanmar;the medium risk regions are mainly located in Japan,South Korea,the most parts of southwestern India,the northern India and the Luzon Island of Philippines;the low risk ones principally are located in most parts of northwestern China.
