本篇内容分两部分,第一部分介绍美国近50年来哥伦比亚等大河流建设的先进经验,主要是以“集约建设”方式,先上游,后下游,即先在上游峡谷地区,修建大调蓄水库,调节迳流,便于防洪、发电,后在下游平缓河段修建低梯级,便于通航发电,其次是,先小后大,即主要大库的装机规模先小一些,等其他干支流水库陆续兴建以后,再成倍扩装,以应需要。第二部分介绍国内黄河规划的情况。认为黄河上游先建刘家峡及低梯级,后建龙头水库龙羊峡是合适的,但下游三门峡建设时,由于对多沙河流建坝经验不足,以致水位过高,回淤影响西安,从而“扩建改建”造成损失,今后要吸取经验,先低后高,先小后大,可以事半功倍。最后一条建议,宜首先抓紧修改长江、黄河流域规划,并采用动态规划方法,可以加快目前大江大河治理开发进度,节省投资,提高效益,有利于我国特色的社会主义建设道路、对今后的小浪底、长江三峡建设,大西南的建设开发均可以起促进作用。
This part is divided into two parts. The first part introduces the advanced experience of the United States such as Colombia and other major rivers in the past 50 years. The first part mainly introduces the construction of major reservoirs in the “upstream” and “downstream” , To regulate the flow, easy to flood control, power generation, after the formation of low-grade river in the lower reaches of the smooth, easy navigation power generation, followed by the first large, that the main large library installed capacity first smaller, and other dry tributaries reservoir one after another to build After that, it will be doubled in size to meet the needs. The second part introduces the domestic Yellow River planning. It is considered that the construction of Liujiaxia and the low cascade first in the upper reaches of the Yellow River and the construction of Longyangxia Gorge in the first reservoir are appropriate. However, due to the lack of experience in the construction of the Sanmenxia River downstream of the Sanmenxia Dam, the water level is too high and siltation will affect Xi’an, thus “expanding Reconstruction ”caused losses, in the future to learn from experience, first low after high, then small, you can do more with less. The last proposal should first pay close attention to the revision of the planning of the Yangtze River and the Yellow River basin and the adoption of dynamic planning methods to speed up the progress of current large river harnessing and development, save investment, improve efficiency and benefit our country’s special socialist construction. In the future, The construction of the Three Gorges of the Yangtze River and the construction and development of the southwest of the Southwest can all play a catalytic role.
