摘　　要：本文采用实测资料分析的方法,研究了黄河下游河道整治工程建设的现状与存在的问题。研究结果表明:小浪底水库运用初期,长期下泄清水,黄河下游河势发生较大变化,个别河段现有河道整治工程的适应性明显不足。为确保黄河下游防洪安全,保障小浪底水库调水调沙,必须修建新布点工程,对一些关键性控制工程进行适当改造,有效控制河势,防止发生"横、斜河"和"滚河"。In the paper,measured data analysis method is adopted to study the present situation and existing problems during the construction of river channel improvement in the lower reaches of Yellow River. The research results show that clear water is discharged for long term at the initial stage of applying Xiaolangdi Reservoir. The river regime is greatly changed at the lower reaches of the Yellow River. The existing river governance projects have prominently insufficient adaptability in some river sections. New distribution projects must be constructed in order to ensure the flood control safety at the lower reaches of the Yellow River and guarantee the water and sand scheduling application in Xiaolangdi Reservoir.Some critical control projects are suitably modified,thereby effectively controlling the river regime, and preventing‘transverse river,inclined river' and‘rolling river'.
