摘　　要：黄河下游山东段河道是典型的二级悬河,威胁堤防安全的洪水是漫滩洪水。本文分析了建国后发生在黄河下游的"58.7"、"82.8"、"76.8"和"96.8"四场典型漫滩洪水的来源、组成及在山东段的运行特性,特别是"96.8"洪水揭示的新特性;分析了山东黄河近十年河道冲淤变化情况和主槽河道输水输沙能力的变化。提出了及时了解上游雨、水情,科学分析洪水来源及组成,结合现行河道边界条件、漫滩洪水运行规律,分析预判可能洪水的演进特性,是做好洪水预报测报重要技术参考。The Shandong section of the lower Yellow River is a typical secondary suspended river .The overbank flood threats the safety of dike .This paper analyzed the source and composition of four overbank floods such as "58.7"、"82.8"、"76.8"and"96.8"which occurred in the Lower Reaches of the Yellow River after 1949 , and the running characteristics in Shandong section , the especially the characteristics revealed by "96.8" flood.It also analyzed the variation of channel erosion , deposition ande water and sediment transport capacity of the main channel in Shandong section of the Yellow River in recent ten years.It suggested that the water and rainfall information in upstream river should be known in time ,the source and composition of flood should be scientificlly analyzed .Accorsing to the current river channel boundary conditions and overbank flood routing law , the paper analyzed the revolution characteristics of possible flood ,which is the important reference for predicting flood .
