The Yangtze River: From Tibetan Plateau to East China Sea

The Yangtze River (Chang Jiang) is the longest river in Asia and the third-longest globally (after the Nile and Amazon), stretching ~6,300 km (3,900 mi).

Source & Course

• Source: Glaciers on the Tibetan Plateau in Qinghai Province (specifically the Geladandong massif, Tanggula Mountains).
• Flow Direction: Eastward across the plateau, then sharply southeast through the Three Gorges, across the Sichuan Basin, and east across central China.
• Mouth: Empties into the East China Sea near Shanghai.

Significance

• Population: Basin supports ~400 million people (1/3 of China's population).
• Economy: Generates ~40% of China's GDP; major industrial, agricultural, and transport corridor.
• Infrastructure: Three Gorges Dam (world's largest hydro plant), Gezhouba Dam, extensive navigation locks.
• Biodiversity: Home to endangered species (Yangtze finless porpoise, Chinese sturgeon, formerly baiji dolphin).
• Culture: Cradle of Chinese civilization; historic sites like Leshan Giant Buddha, Fengdu Ghost City, Shibaozhai Pagoda.

Challenges

Pollution, sediment trapping by dams, overfishing, habitat fragmentation, and climate change impacts on Tibetan glaciers threaten the river's ecological and economic viability.
