四川盆地
The entirety of the Sichuan Basin is drained by the Yangtze River and its tributaries. The main stem of the Yangtze, the Jinsha River, enters the basin in the south at Yibin where it meets the Min River, which enters the basin from the northwest at Dujiangyan City and flows southerly to meet the Jinsha at Yibin where together they form the Yangtze in name. The Dadu River enters from the west and joins the Min at Leshan. The Jialing River enters from the north and flows across the entire width of the Sichuan Basin to meet the Yangzte at Chongqing. Northeast of Chongqing, the Yangtze cuts an outlet through the mountains at the eastern edge of the basin known as the Three Gorges. Other significant rivers almost wholly within the Sichuan Basin include the Tuo River, the Fu River, and the Qu River.
