摘要 河流分段方法研究属于河流动力学与河流地貌学的交叉研究领域,其研究成果是流域规划、河流管理与河道治理等的重要基础与依据。基于Schumm河流分区理论,总结了"三河段分段法";基于地貌临界条件,提出了"控制节点分段法";综合提出并推荐了"最大五河段分段法"。根据十大江河河流分段实践,检验了"最大五河段分段法"的适用性与有效性。分析结果表明,该方法与十大江河的分段实践吻合一致,值得推荐。 The study of large river segmentation method belongs to the cross field of river dynamics and fluvial geomorphology, and the research achievement is an important basis for river basin planning, river management and regulation. Based on Sehumm' s theory on river segmentation, the 3 - reach river segmentation method is firstly summarized. According to the theory of morpho- logical threshold condition, the method of control - node river segmentation is developed. The method of the maximum 5 - reach river segmentation is proposed and recommended through comprehensive consideration. The applicability and feasibility of the maximum 5 - reach river segmentation method is compared and checked by the river segmentation practice of 10 large rivers in the world. The results show that the maximum 5 - reach river segmentation method is well consistent with the segmentation practice of the I0 large rivers and therefore is worth recommending.
