摘　　要：在分析黄河下游游荡型河段治理现状及存在问题的基础上,结合水沙变化情况,指出了现行河道整治工程布局的局限性,以今后防洪安全、供水安全、生态安全、滩区安全等多种功能需求为背景,提出了进一步完善黄河下游河道整治工程布局的思路和平面型式。治理思路为:明确中水整治规模,适当布置小水整治工程,完善工程布局;加强畸形河势治理;重点河段强化边界控制;防洪工程建设与水生态保护协调发展。整治措施包括:1对已建的直线送溜段坝垛进行改建、加固;2按控制小水的要求对控导工程适当下延或上延,上延时要结合主河道控制线进行;3对特别重要的河段,尤其是两岸有大量引水需求的河段,适当辅以对口丁坝双岸整治以确保河势的稳定;4若局部河段出现畸形河势,则抢险工程宜结合主河道控制线布置。On the basis of analysis of the status quo and the existing problems of the river training of the lower Yellow River wandering reaches and considering the changes of water and sediment,the paper pointed out the limitation of the existing layout of river training projects and on the background of multifunctional requirements such as flood control safety,water supply safety,ecological safety and floodplain safety,it proposed the training ideas and plain pattern for further improving the layout of the lower Yellow River training projects. The training ideas are to make clear the medium water training scale and arrange properly small water training projects to improve project layout; to strengthen malformed river regime training; to strengthen border control at key river channels; to coordinate development of flood control works construction and water ecology safety. The training measures include： 1） To transform or reinforce the built dam buttresses in the straight flow sending channels; 2） To extend upstream or downstream the controls works as required by small water control,and the upstream extension should be aligned with the main channel control line; 3） To adopt properly face-to-face groins of both bank training as supplement to ensure river regime stability for specially important river channels,especially those with large water diversion requirements from both banks and; 4） If malformed river regimes appear in some river reaches,the emergency works should be arranged along the main river channel control line.
