摘　　要：根据对新中国成立以来黄河下游历次漫滩资料的分析,小浪底水库建成前约2年漫滩一次,建成后约3年漫滩一次。随着黄河调水调沙的继续实施,黄河下游河道的过洪能力将会得到进一步提高,加上工农业用水的增加、中游水土保持工程建设的不断完善,小浪底水库对中常洪水的拦蓄率将会提高,发生大于平滩流量洪水的概率会更低,有希望达到5年一遇。因此,从技术角度分析黄河下游滩区具备享受国家蓄滞洪区运用补偿政策是可行的。According to historical data of overbank flooding in the lower reaches of the Yellow River since the founding of new China, it is found that overbank flooding occurred once in 2 years or once in 3 years respectively before and after the completion of the Xiaolangdi Reservoir. Along with the operation of water and sand regulation of the Yellow River, flood carrying capacity of river courses in the lower reaches of the Yellow River has been continuously improving. Together with the increase of industrial and agricultural water use and improvement of water and soil conservation in the middle reaches, flood storage capacity of medium flood of the Xiaolangdi Reservoir shall be enhanced and may reach to once in 5 years for the probability of flood,which bigger than the flat beach runoff shall be lower. Thus it is feasible lo issue compensation policy to flood retention and storage areas in flood plain areas in the lower reaches of the Yellow River.
