College of U rban and Environmental Sciences, Northeast Normal University, Changchun , China; 2. Songliao W ater Resources Comm ission, M inistry ofw ater Resources, Changchun , China) Abstract:A lthough many studies have m ade assessment of flood /waterlogging disaster risk now, they have not de2 veloped an integrated index. This study p resents a m ethodology for risk assessment and zoning of flood /waterlogging in m iddle and lower reaches of L iaohe R iver of Northeast China based on geographical information system s ( GIS) and the technology of natural disaster risk assessment from the viewpoints of climatology, geography, disaster sci2 ence, environmental science and so on. Key words: flood /waterlogging disaster risk; m iddle and lower reaches of L iaohe R iver; GIS; natural disaster risk assessment; flood /waterlogging disaster risk index( FDR I),,,,,, [ 1 7 ],, GIS,, : ( flood /waterlogging disaster risk index, FDR I), : ; : : (2004BA528B - 3-1) ;; ( ) : ( ),,,,.
