1946年以来,关于黄河下游根治的认识,首先经过“治本靠拦沙”到“下游也有治本任务”的重大转变,然后,是对“下游也有治本任务”进一步全面深入的分析论证。“黄河下游也有治本任务”的论证具有高度的科学性。重点对围绕“下游也有治本任务”的研究作了梳理总结,主要进展为,多来多排现象的发现、“小水挟沙”的不利影响和对洪水重要性的充分认识、山东河道的输沙潜力及窄深河槽排洪输沙能力的论证、泥沙多年调节思想的形成和发展。通过水库水沙调节优化进入下游河道的水沙过程。将下游高村以上宽河道整治成窄深河槽,使整个下游形成一个输沙通道输沙入海。
Since 1946, the understanding on the root causes of the lower reaches of the Yellow River first has undergone a major shift in the status quo after the “permanent cure” and “downstream” tasks. This is followed by a further comprehensive and in-depth study on “downstream tasks also” Analysis and demonstration. “The lower reaches of the Yellow River there is a cure task ” argument has a high degree of scientific. The focus is on the research on the “downstream tasks also”. The main progresses are as follows: the discovery of multi-row phenomena, the adverse effects of “little water reefs” and the full understanding of the importance of floods, The sediment potential of Shandong river channel and the capability of drainage and sediment transport in narrow and deep river channels, the formation and development of sediment regulation idea for many years. Through the reservoir water and sediment regulation to optimize the downstream water and sediment process. The upper reaches of the village will be widened above the width of the river into a narrow river, so that the entire downstream to form a sediment transport channel into the sea.
