三峡水利枢纽是治理、开发长江的一个控制性枢纽。它效益巨大,规模宏伟,将是世界上最大的一个综合利用水利枢纽。水库正常蓄水位200米时,总库容约700亿立米.可提供约400亿立米的防洪库容,是彻底解决长江中下游防洪的关键工程;水电站装机2500～3000万千瓦,约相当我国目前总装机容量的一半。水库回水淹没了重庆以下全部川江天险,并增加了坝下河道枯水期航深、使万吨级船队可由上海直通重庆;可利用水库蓄水,为中线南水北
The Three Gorges Project is a controlled hub for harnessing and developing the Yangtze River. It is of great benefit and magnificent scale, and will be the largest integrated hydropower project in the world. The reservoir capacity of 200 meters when the normal water level, the total storage capacity of about 70 billion cubic meters. Can provide about 40 billion cubic meters of flood control capacity is the key to solve the flood control in the middle and lower reaches of the Yangtze River; hydropower station installed 2500 ~ 300000000 kilowatts, about our current total Half of installed capacity The backwater of the reservoir inundated all the following natural hazards in the river below Chongqing and increased the dry season depth of the lower reaches of the dam so that the 10,000-tonnage fleet could pass through Shanghai directly to Chongqing. The reservoirs could be used to store water for the mid-line of Nanshui North
