長江是亞洲最長、世界上第三長的河流。長江流經多種不同的生態系統，是諸多瀕危物種的棲息地，灌溉了中國五分之一的土地。長江流域(river basin)居住着中國三分之一的人口。長江在中國歷史、文化和經濟上起着很大的作用。長江三角洲(delta)產出多達20%的中國國民生產總值。幾千年來，長江一直被用於供水、運輸和工業生產。長江上還坐落着世界上最大的水電站。 The Yangtze River is the longest river in Asia and the third longest one in the world. Flowing through many different ecosystems, it is the habitat for a whole host of endangered species and irrigates one fifth of the land in China. One third of Chinese population live in the Yangtze river basin. The Yangtze river plays an important role in the history, culture and economy of China and contributes to as much as 20 percent of the Gross National Product of China. It has been used for water supply, transportation and industrial production for several thousand years. Also, on the Yangtze river lies the largest hydropower station in the world.
