Where is the source and destination of Tuojiang River?

The source of Tuojiang River is Jiuding Mountain on the northwest edge of Sichuan Basin, and the destination is Zhao Zhen Town, Jintang County.

With a total length of 765,438+02 km, the Tuojiang River flows southward into Zhao Zhen, Jintang County, where it flows into four tributaries of the upper reaches of the Tuojiang River, namely Pi River, Qingmin River, Juanjiang River and Shiting River, passes through Jintang Gorge in Longquan Mountain, passes through jianyang city, ziyang, Zizhong County, Neijiang City, Zigong City and Fushun County, and flows into the Yangtze River in Luzhou City.

Tuojiang River is a tributary of the upper reaches of the Yangtze River. Located in the middle of Sichuan Province, China. Tuojiang River Basin is a subtropical warm and humid weather, with the annual average temperature of the whole basin 17. 1℃. The annual average precipitation is about 1200~ 1700 mm in the upstream, 900~ 1500 mm in the upstream and 870 ~100 mm in the middle and lower reaches.

Tuojiang River originated from Jiuding Mountain at an altitude of 4,984 meters. The upstream source is divided into three streams. East source: Mianyuan River length 180 km, middle source: Shiting River length 14 1 km, and west source: Juanjiang River length 139 km, which meet near Zhao Zhen in Jintang County to form the main stream of Tuojiang River. Moreover, the water network of the Minjiang River is staggered, the basin is disrupted, and the water of the Minjiang River is still flowing in the Tuojiang River.

Characteristics of Tuojiang River:

The three tributaries of the upper source of Tuojiang River cross the geotectonic structure along the terrain, and enter the Sichuan Basin from northwest to southeast, carrying a large amount of sand and gravel to pile up into layers of alluvial fans in front of Longmen Mountain, and gradually become the land of abundance in Chengdu Plain. The upstream source tributaries traveling in the middle and low mountainous areas have narrow valleys and steep rock slopes.

The water surface width of some river sections is only10 ~15m, and the water falls in the river and deep pools come and go, which makes the water flow very turbulent, splashing and vibrating constantly. After the river came out of the water, it entered the Chengdu Plain, where the valley suddenly widened, the water flow suddenly slowed down, and the gravel in the water stopped, forming a gravel river bed. The width of the valley reaches one or two kilometers in some paragraphs.
