Abstract: In order to understand and master occurrence regularity of waterlogging disaster in winter vegetables, to reduce disaster losses, and to ensure the grain production, a winter vegetable seedling waterlogging disasters risk zoning was done by taking the effects of weather and earth’s surface environment integrated into account in this study. For weather, the intensity of precipitation, number of precipitation process was taken. And earth’s surface environment, topography, land cover, soil texture was saw as risk pregnant environment. Hainan island winter vegetables seedling waterlogging high-risk areas mainly in the eastern and northern parts; northwestern region, and little part of northern was moderatewaterlogging risk zone; central, southern and the western region of occurrence of waterlogging disaster risk was relatively low. The zoning had a high spatial resolution and useful to crop layout and enhance the security of planting winter vegetables.
