Yangtze River (Chang Jiang)

The Yangtze River (also called the Chang Jiang) is about 3,915 miles (6,380 km) in length and is considered the third longest river in the world. It is located in the People’s Republic of China and it flows from its source in the Qinghai Province, to the East China Sea at Shanghai. Because it is the largest river in this region it is important economically, historically and culturally. It also id the home of the world’s largest hydro-electric power system, the Three Gorges Dam.

The Yangtze, Yangzi or Cháng Jiāng is the longest river in Asia. The Yangtze drains one-fifth of China's land area and its river basin is home to one-third of China's population. Along with the Yellow River, the Yangtze is the most important river in the history, culture and economy of China. The prosperous Yangtze River Delta generates as much as 20% of China's GDP. The river is an important physical and cultural dividing line between North and South China. Chinese living north of the Yangtze speak varying dialects of Mandarin. Most of the provinces south of the river have native Sinitic languages that are unintelligible to Mandarin-speakers.

The Yangtze River flows through a wide array of ecosystems and is itself habitat to several endemic and endangered species including the Yangtze River dolphin (now extinct), Chinese alligator, and the Yangtze sturgeon. For thousands of years, man has used the river for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The Three Gorges Dam on the Yangtze River is the largest hydro-electric power station in the world. In recent years, the river has suffered from industrial pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves. A stretch of the Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site.
