本文就综合治理开发长江问题,研究了开发重庆至三峡川江河段三峡水利枢纽128m、150m、170m、175m及200m五种水库正常蓄水位的比较方案。在五种比较方案中,128m方案是两级开发方案,其发电、防洪、航运等综合利用效益太小;200m方案是一级开发方案,发电、防洪、航运等综合利用效益巨大,但淹没损失太大,很不现实,均予放弃。150m、170m和175m方案都是一级开发方案。170m和175m方案比150m方案淹没损失和总投资都增加不太多,而发电、
In this paper, on the issue of comprehensive management and development of the Yangtze River, this paper studied the comparison schemes for developing the normal water storage at 128m, 150m, 170m, 175m and 200m of the Three Gorges Project between Chongqing and the Three Gorges River. Among the five comparison schemes, the 128m scheme is a two-level development scheme and the comprehensive utilization efficiency of power generation, flood control and shipping is too small. The 200m scheme is a first-level development scheme. The comprehensive utilization of power generation, flood control and shipping is of great benefit but the inundation losses Too large, very unrealistic, all give up. 150m, 170m and 175m programs are a first-class development programs. 170m and 175m than the submerged 150m program losses and total investment increase is not much, and power generation,
