【摘要】：基于Schumm河流分区理论与笔者"最大5河段分段法",优化提出了"河流5区分段法",即:以流域分区为主导("体"),以干流河道分段为目标("用"),先按照河源、上游、中游、下游和河口5区进行流域分区,后选取河势和(或)汇流控制节点进行干流河道分段,综合确定合适的河流分段数;基于10大江河分段实践,检验了"河流5区分段法"。长江干流分段实践可总结为兼顾流域与河道特性、流域特性主导和河道特性主导3类分段方法;基于"河流5区分段法",长江干流推荐划分为5段(长江源—直门达/巴塘河口—宜昌—湖口—徐六泾—长江口)、3段(长江源—宜昌—湖口—长江口)和2段(长江源—宜昌—长江口);长江干流其他分段方法分别基于河流名称、水系划分、行政区界、河流指标和专业管理等。
[Abstract]:Based on the theory of Schumm river zoning and the author's "maximum 5 reach segmentation method", this paper optimizes the "River 5 Segmentation method", that is, taking watershed zoning as the dominant ("body"), taking the main stream as the target ("use"), and first according to the source, upper and middle reaches of the river. The river regime and / or confluence control nodes are selected to divide the main stream, and the appropriate number of river segments is determined synthetically. Based on the practice of 10 major river segments, the "River 5 Segmentation method" is tested. The practice of the main stream segmentation of the Yangtze River can be summed up as taking into account the river basin and river channel characteristics, watershed characteristics leading and river channel characteristics leading three types of segmentation methods; Based on the "River 5 Segment method", the main stream of the Yangtze River is recommended to be divided into 5 sections (source of the Yangtze River, Zhimenda / Batang Estuary, Yichang, Hukou, Xuliujing, Changjiang Estuary) and 2 sections (source of the Yangtze River, Yichang, Hukou and Changjiang Estuary). Source of the Yangtze River-Yichang-Yangtze River Estuary); other segmentation methods of the Yangtze River main stream are based on the name of the river, Water system division, borderline, river index and professional management.
