Abstract: Based on the system of agrometeorological disaster,disaster risk theory and materials including daily precipitation data(from September to November) of 18 meteorological stations from 1961 to 2012,geographic information data and data of cultivated area,winter vegetables planting area in Hainan Island,the hazards of disaster causing factors and sensitivity of disaster pregnant environments and vulnerability of storm flood disaster to winter vegetables in Hainan Island were constructed and divided by using GIS and methods of weighting and natural breaks.Furthermore,with the help of the 3 indices,a comprehensive risk index model of storm flood disaster to winter vegetables was constructed to zone the risk of storm flood disaster to winter vegetables in Hainan Island.The results showed that the highest and second highest risk zones of storm flood disaster to winter vegetables were located in the northeastern and eastern areas of Hainan Island such as Wanning, Qionghai,Tunchang and Lingshui.The lowest and secondlowest risk zones were located in the western areas.Actual disaster results were matched with risking zone,which provides scientific basis for reducing and avoiding disaster risk and rational production layout of winter vegetables in Hainan Island.

Key words: Storm flood, Agro meteorological disaster, Risk assessment and zoning, GIS, Winter vegetables
