The Qujiang River is the largest tributary of the left bank of the Jialing River in the Yangtze River. It is also known as Qu River. It was known as "diving" in ancient times.

The Qujiang River Basin is one of the most fierce areas of water in the upper reaches of the Yangtze River. From the map, the Qujiang River Basin is a fan -shaped, the tributary on the left is the Bazhi River in the middle of the Pakistan, and the right side is the state river that crosses Dazhou. Each year, the water vapor in the southeast is very easy to form a parallel and stable rain belt in the southern foot of Qinba Mountain. The probability of heavy rainfall at the same time in the entire basin is greater.

From 2003 to 2011, the Qujiang River Basin almost burst into floods in the past few years. In the flood season in 2021, the Qujiang Basin became the most frequent area in Sichuan flood disasters. At that time, the Qujiang Basin suffered 7 rounds of rainfall, causing a lot of property losses.

In order to prevent the response to the floods of the Qujiang River, Sichuan Province has planned and constructed three backbone water conservancy projects such as Tuoxikou Reservoir, Huangshipan Reservoir, and Hongfu Cave Reservoir. At present, the Tuchankou Reservoir is under construction, and the Huangshipan Reservoir has been basically completed. The Hongfu Cave Reservoir passed the water storage stage in June this year. The flood prevention benefits are gradually being played.
