The Yangtze River: China's Golden Artery

The Yangtze River (Chang Jiang — "Long River") is Asia's longest river and the third-longest globally (after the Nile and Amazon). It flows 6,300 km (3,915 mi) from the Tibetan Plateau to the East China Sea, entirely within China.

Source to Sea

• Source: Glaciers of the Tanggula Mountains (Qinghai-Tibet Plateau), ~5,200 m elevation.
• Upper Reaches (Jinsha Jiang): Deep gorges, steep gradients (Tiger Leaping Gorge, Three Parallel Rivers UNESCO site).
• Middle Reaches: Sichuan Basin, Three Gorges (Qutang, Wu, Xiling), then the vast Jianghan Plain.
• Lower Reaches: Broad, navigable channel through Wuhan, Nanjing, to the Yangtze Delta (Shanghai).
• Mouth: East China Sea near Shanghai, forming a massive estuary.

The Yangtze Basin: China's Core

• Area: 1.8 million km² (~1/5 of China's land).
• Population: ~400 million (nearly 1/3 of China).
• Economy: Generates ~45% of China's GDP. Major cities: Chongqing, Wuhan, Nanjing, Shanghai.
• Agriculture: Rice bowl of China (middle/lower reaches).
• Transport: Navigable year-round to Chongqing (2,400 km inland). "Golden Waterway."

Three Gorges Dam: Engineering Marvel and Controversy

World's largest hydropower project (22.5 GW). Benefits: flood control, navigation improvement, clean energy. Costs: 1.3 million displaced, ecological disruption, sediment starvation downstream, seismic risk.

Cultural Soul

The Yangtze is the "Mother River" of Chinese civilization—cradle of ancient cultures (Ba, Chu, Wu), inspiration for poets (Li Bai, Du Fu), and symbol of national unity. Its health is China's health.
