摘　　要：黄河口治理具有长期性和复杂性,探求不同治理措施条件下尾闾河段冲淤规律是十分必要的。根据原型资料和模型试验结果,分析了清水沟改道和清8改汊对河口淤积延伸的影响,探讨了河口段挖河疏浚对尾闾河段水位、河床冲淤变化的影响。认为黄河河口采取有计划的改汊和长期挖河疏浚,可延长河口现行流路行河的年限。但从长期看,河口段较大规模的改道是不可避免的。In connection with the estuary regulation of Yellow River, the effects from the channel-change of Qingshuigou Course and the branch-change of Qingba Anabraneh for Yellow River on the extension of sedimentation are analyzed based on the prototype data and the model test result concerned, in which the effects from the dredging at the estuary on the water level of the tail course and the change from the river bed desihation are discussed. It is considered that the flow-period of the exsting river flow path can be prolonged, if the well-planned branch-change and long-period dredging are carried out. However, the large scale channel-change is inevitable from the viewpoint of a long period.
