1.治水防洪效益。建成后,能控制百年一遇洪水,确保防洪体系内近2300万亩耕地、1500万人民生命财产和京九、京广铁路大动脉的安全。 2.水力发电效益。按照工程设计,年均发电量847亿度,加上葛洲坝年均总发电量可达1050亿度,可创产值105亿元。3.供水灌溉效益。三峡工程建成后,如实施南水北调,可解决北京、天津、保定、石家庄、郑州、焦作等城市年缺水约400亿立方米,能解决粮棉主要产区年缺水近700亿立方米的灌溉任务。
1. Flood control benefits. After its completion, it can control floods in a hundred years and ensure the safety of nearly 23 million mu of arable land, 15 million people’s lives and property and the aorta of the Beijing-Kowloon and Beijing-Guangzhou Railway in the flood control system. 2. Hydroelectric benefits. According to the engineering design, the average annual generating capacity of 84.7 billion degrees, plus Gezhouba annual average total generating capacity of up to 105 billion degrees, a record 10.5 billion yuan output value. 3. Water supply irrigation benefits. After the completion of the Three Gorges Project, such as the implementation of the South-to-North Water Diversion Project, can solve the annual water shortage of about 40 billion cubic meters in cities such as Beijing, Tianjin, Baoding, Shijiazhuang, Zhengzhou and Jiaozuo and can solve the irrigation shortage of nearly 70 billion cubic meters task.
