【摘要】 从致灾因子、孕灾环境的洪水灾害系统论入手,以晋江流域为研究范围对流域洪水危险性进行评价。应用GIS、层次分析法、模糊综合评价法,选取降雨、地形、河网等五个指标,综合计算得到流域洪水危险性等级和指数图。结果表明晋江流域洪水危险性高风险区和中高风险区主要位于中下游干流周边及入海口处,特别是下游东田溪附近,流域内部也有三个高风险区,主要位于西溪源头区、东溪的支流桃溪附近和诗溪附近。更多还原

【Abstract】 From the strat with theory of flood disaster System approach to evaluate the Flood Hazard Intensity in Jinjiang River Basin.Application of GIS,analytic hierarchy process,fuzzy Synthesis evaluation method,select the rainfall,terrain,river network etc as the indicators calculated the river basin flood hazard level and the index map.Results showed that the flood hazard of Jinjiang Basin flood of high-risk areas mainly located in and around the River estuary,particularly the lower reaches of the river near Dongtian.Internal basin also has three high-risk areas,mainly located in the source area of Xixi River,and located near the river Taoxi River which is the tributaries of Dongxi River and near Shixi River.更多还原
