【 摘 要 】

Through the analysis of major factors within the generation of floods, floods risk assessment index model is explored based on GIS (Geographic information system). Weighting the index system and zoning with different risk levels is used to conduct floods disaster risk assessment in Guangxi province. As seen from the result in the project, the floods disaster risk assessment map, that southern coastal regions and central basin of Guangxi are high flood risk zone, such as Liujiang County, Wuming County, Hepu County. Western regions are in good conditions with relatively low flood disaster risk, like Jingxi county and Youjiang county. On that basis, some constructive suggestions are proposed.
