Majestic world-famous Dam
葛洲坝 巍巍大坝 世界闻名
Yangtze River Ying Choi Ha, Alpine Valley dam ages. Standing Xiling Gorge mouth, this world-class view Gezhouba Water Project, saw it as a shining pearl inlaid in the beautiful scenery of the Three Gorge, natural beauty and artificial wonders of each other, complement each other, for the beautiful Three Gorges added a red-letter stroke. Three Gorges section of steep slope, a large gap, Gap long deep valley, not only rich in water resources, there are good dam site, is to build large-scale water conservancy project an ideal location. Mao Zedong wrote this "gorges" a magnificent poem, this is not the whim of the leaders, but he used the language of poetry for the people depicted a magnificent blueprint for the future of the Three Gorges. Zhou made to the National People "in order to fully take advantage of five hundred and forty million kilowatts of hydropower resources and construction hub of the Yangtze River water to fight the ambitious goal," he also said: "If the construction of the Three Gorges Water Control Project, the Yangtze River flood control have not completely resolved, but it was not comprehensive utilization problems. we built the Three Gorges Dam, is a fundamental solution to the threat of flooding to realize Chairman Mao 'gorges' a grand ideal, it can never benefit the people. " 1958, February and March, Zhou Enlai in Li Fuchun, Li Xiannian, accompanied by two comrades, up river from Wuhan, visited the Three Gorges dam area reconnaissance of two Three Gorges, the Yangtze River after they identified the recent governance and long-term planning. Winter 1970, Zhou Enlai personally presided over the meeting of the Central Political Bureau to study and discuss the Three Gorges dam project components - Gezhouba project related issues. Subsequently, Mao instructed "in favor of the construction of the dam." December 30 that year, construction Gezhouba fighting started. Gezhouba project is located west of the Yangtze River in Yichang City, the Three Gorges dam site from the export of South Pass in 2.3 km, 37 km from the Three Gorges Dam site, 4 km from Yichang city, due to the small dam across the river Ge island continent its name. Ge Jiang, here there are two small islands Chau Island and the West Dam, the Yangtze River is divided into three waterways. After the completion of the dam, raising water level in the Yangtze River, the Three Gorges effectively improve the natural course. "North Korea speech Bai Di Choi, Trinidad Jiangling day also. Strait ape the sound could not cry, my boat these ten thousand mountains." Is no longer a good poet's exaggeration and fantasy, has now become a living reality. Ticket price: 15 yuan (now stop tour)
