The Three Gorges Dam (Chinese: 长江三峡大坝) is a hydroelectric river dam that spans the Yangtze River in the town of Sandouping, located in the Yiling District of Yichang, in Hubei province, China. It is the world's largest electricity-generating plant of any kind.The dam body was completed in 2006. Except for a ship lift, all of the originally planned components of the project were completed on October 30, 2008 when the 26th generator was brought into commercial operation. Currently, it contains 26 completed generators in the shore power plant, each with a capacity of 700 MW. Six additional generators in the underground power plant are being installed and are not expected to become fully operational until around 2011. Coupling the dam's 32 main generators with 2 smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW. The project produces hydroelectricity, increases the river's navigation capacity, and reduces the potential for floods downstream by providing flood storage space. From completion until September 2009 the dam has generated 348.4 TWh of electricity, covering more than one third of its project cost.The project management and the Chinese state regard the project as an historic engineering, social and economic success, with the design of state of the art large turbines, and a move toward the reduction of greenhouse gas emissions. However, the dam has also flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The building of the dam has been a controversial topic both in China and abroad.希望帮到你啦~
The Three Gorges Dam project is one of the most controversial international river issues. The dam would cross the Yangtze River, which is a the third largest river in the world, at a point where the river is a mile wide. The 610 foot dam would create a 39 billion cubic meter reservoir that would stretch for 400 miles. 3 Not only is this the largest dam ever built, it is the largest construction undertaking. Financial backing has come from many national and international sources, including United States companies. China has also sought outside engineering and construction consulting from companies including Caterpillar Construction Company. A dam on the Yangtze River was first proposed by Sun Yatsen in 1919 for power generation purposes. This prosoal never came about because of economic and political strife. Many leaders dreamed of taming the Yangtze River. Life along the Yangtze River can be treacherous because of the deadly flooding known to devastate cities and lives. 6Most of the controversy involves the relocation of a million people who live in areas to be submerged, the potential loss of many archeological artifacts, and the environmental disruption the dam will cause. Dai Qing, a Chinese journalist wrote the book, Yangtze! Yangtze!, which protested the dam in 1989. The book was banned and Qing was imprisoned for 11 months. 5 This type of behavior on the part of the Chinese government has made many skeptical about possible corruption in the project.China has also recieved much criticism for the expensive and risky project. Many say that building smaller dams along the river rather than one enormous dam would be more efficient. Some have even claimed the dam is being used as a monument to the success of socialism. 5.Phillip Williams of the International Rivers Network says, "There is a grandiosity that appeals to a megalomaniac instinct that overrides not only economic considerations but sometimes even sound political judgment." Completion dates are set for 2009 and by 2003 China should be able to start generating power for the nation
