赵口—黑岗口河段一直以其河势变化复杂而成为黄河下游最难治理的游荡型河段之一。通过总结该河段不同时段河势演变过程，在系统分析主流变迁过程和断面冲淤情况的基础上，总结了该河段河道整治工程的靠河情况。河段内河道整治工程的修建主要集中在1986年以后，但该河段主流仍没有很好地受到工程控制。为进一步控制主流，近期首先应解决赵口—三官庙河段的流路问题。
趙口—黑崗口河段一直以其河勢變化複雜而成為黃河下遊最難治理的遊盪型河段之一。通過總結該河段不同時段河勢縯變過程，在繫統分析主流變遷過程和斷麵遲淤情況的基礎上，總結瞭該河段河道整治工程的靠河情況。河段內河道整治工程的脩建主要集中在1986年以後，但該河段主流仍沒有很好地受到工程控製。為進一步控製主流，近期首先應解決趙口—三官廟河段的流路問題。

Zhaokou—Heigangkou reach with its complex river regime evolution in the Lower Yellow River is one of the most difficult sections to gov-ernance. In this paper,based on summarizing the river regime evolution process in the different periods,systematical analysis of the mainstream change process and scouring and silting of cross sections,the situation of stream close to river training works had been concluded and the character-istics of river regime evolution had been discussed. The river mainstream was not well under the control though many groin were constructed since 1986. In order to further control the mainstream,it is necessary to make a plan to deal with the wandering mainstream in Zhaokou-Sanguanmiao reach in recent years.
