There are many water in ancient Shu, especially in Chengdu Plain.

The Chengdu Plain is raining, and a large tributary of the Yangtze River flows from the north to south of the Chengdu Plain from north to south. The Minjiang River waterway is higher than that of most of the Chengdu Plain, which is a "hanging river". Therefore, in ancient times, the water of the Minjiang River suffered from a long -term disaster, and the invasion of people's livelihood became a major obstacle to the survival and development of the people of the Shu land. "The rivers are swinging (yù), and the Shu people are a few fish." It was a true portrayal of the Chengdu Plain that was raged by floods at that time.

In the fifty year of King Qin Zhaoxiang (256 BC), Li Bing, the eunuch of Shu County, Qin Guo, learned the experience of water control in his predecessors, led the local people, and presided over the construction of Dujiangyan. By building main projects such as the water -to -mouth division of the water dyke, the flying sand weir overflowing road, and the bottle mouth into the water mouth, the water flow of the Minjiang River was divided into two, and one of the water flow on the east was introduced into the Chengdu Plain.

After the completion of Dujiangyan, the water damage of the belly of the Chengdu Plain was gradually controlled. The violent Minjiang River moved towards "tame". Runzawa's Shu Di was more than 2000 years.

The Minjiang River is an important tributary of the upper reaches of the Yangtze River. In addition to irrigation, the Minjiang Shipping has also been very developed in the past. It has provided huge impetus for the economic and social development of the watershed. It is known as the "golden waterway" of Sichuan. The earliest transportation of Minjiang Shipping traced back to the Warring States Period. After the Minjiang River, Chengdu realized Tongjiang Dahai, and Tongjiang Zhejiang and other areas passed water to contact with water. Later, due to various factors, the Shipping of the Minjiang River gradually declined.

Today, the Minjiang River is one of the "four horizontal" (the Yangtze River trunk line) of the national high -level channel "four vertical, four horizontal two networks". In June 2022, the Sichuan Provincial Department of Transportation issued the "Shipping Development Plan of the Chengdu to Leshan Section of Minjiang River", the planned scope was 186 kilometers from the Jiugan Bridge from the Chengdu Chengdu to Leshan.

According to the above plan, by 2035, the 115 -km channel from Pengshan River estuary to Leshan Xiao Gong's mouth was built to build a CD -level channel, which can pass thousand tons of ships all year round. Established as a puppetway to achieve Quanjiang channels from the Chengdu to Leshan section of the Minjiang River.
