对三峡工程的研究可以追溯到本世纪二十年代孙中山先生的《实业计划》、三十年代恽震等三位中国工程师的首次查勘、四十年代美国的萨凡奇计划。新中国成立后不久即开展全面的长江流域规划工作,长办从1954年开始研究三峡。它是开发治理长江的主体工程,具有巨大的防洪、发电、航运以及旅游水产等多方面的综合效益。三十余年来研究的水库正常蓄水位的范围从128米到260米。蓄水位越高综合效益越大,但淹没损失
The study on the Three Gorges Project can be traced back to the “Industrial Plan” of Dr. Sun Yat-sen in the 1920s, the first survey of three Chinese engineers such as the earthquake in the 1930s, and the Plan of the United States in the 1940s. Shortly after the founding of New China, a comprehensive planning of the Yangtze River Basin was carried out. The CFO began to study the Three Gorges from 1954 onwards. It is the main project of harnessing and harnessing the Yangtze River and has enormous comprehensive benefits such as flood control, power generation, shipping and tourism and fisheries. For more than thirty years, the normal reservoirs of reservoirs studied range from 128 meters to 260 meters. The higher the water level, the greater the overall efficiency, but submerged losses
