What is the biggest tributary of the Dadu River? 1 Dadu River is the largest tributary of Minjiang River.

Dadu River is the largest tributary of Minjiang River, and there are many opinions about its source. There is a saying that the Dadu River originated in the southern foot of Guoluo Mountain in jiuzhi county, Guoluo Prefecture, Qinghai Province. Guoluo Mountain has a name that many donkey friends are familiar with-Nianbaoyufeng. Another way of saying it is that the source of the Dadu River is the Makehe River in Dari County, Guoluo Prefecture, Qinghai Province, and the downstream is called Zumuzu River.

In addition, there is a Chuska River originating from banma county, Guoluo Prefecture, Qinghai Province. It is generally considered to be the western source of the Dadu River, and its upstream is called the Dokke River (or Dukke River). Chuojia River and Zumuzu River meet near Gada, west of Marcand, the capital of Aba Prefecture, Sichuan Province, and are called Dajinchuan.

Hydrological characteristics of Dadu River:

The upper reaches of the basin have a plateau and mountainous climate, with cool Leng Xia in winter and little rain all year round. The annual precipitation is 500-750 mm, mainly snow, and the snow-covered period can reach 5 months.

The rest of the region has a monsoon climate, and the overall characteristics are warm in winter and hot in summer, rainy and humid. Annual precipitation 1 0,000mm, Luding and Shimian right bank area 1 0,200-1 500mm, and some downstream areas can reach10,400-1900mm. Heavy rains are mostly concentrated in the middle and lower reaches from May to September, especially in July and August.

River runoff mainly comes from precipitation. According to the 45-year statistics of the downstream Fulu Town Hydrological Station, the average flow for many years is1500m3/s. There is abundant groundwater and ice melt water (accounting for about 20% of the total) for regulation, and the runoff changes little.

What is the biggest tributary of the Dadu River? Dadu River is the largest tributary of Minjiang River in China.

Dadu River was called Beijiang, Lishui, Sushui, Moshui, Dadu River, Mengshui, Lushui, Liuhe, Yang Yang, Yangshan, Zhong Zhen, Yutong, Jinchuan and copper river. Located in the midwest of Sichuan Province, People's Republic of China (PRC), it is the largest tributary of Minjiang River, a tributary of Yangtze River in China.

Originating at the southern foot of Golog Mountain in Anima, Yushu Tibetan Autonomous Prefecture, Qinghai Province, the Zumuzu River (Marco River and Ake River) from the upper source flows into Mosuo River and Chuojia River (Duke River and Duoke River) in Marcand County, Aba County, which is called Dajinchuan, flows southward through Jinchuan County and Danba County, flows into Xiaojinchuan County in the east of Danba County, and then turns around through Luding County and Shimian County, which is called the total length of Dadu River100. There are 28 tributaries with a drainage area exceeding 1000 km2, and 2 tributaries with a drainage area exceeding 1000 km2, with a river network density of 0. 39.

Traditionally, Dadu River is the largest tributary of Minjiang River. Of course, the "Minjiang River" I mentioned here only refers to the first-class tributary of the Yangtze River, that is, the Minjiang River, which joins the Jinsha River near Yibin City, Sichuan Province and Shuifu City, Yunnan Province, rather than the Bailong River, an upstream tributary of Jialing River, a first-class tributary of the Yangtze River.

But at present, the view that "Dadu River is the largest tributary of Minjiang River" has been denied. Because if the Dadu River, the actual main stream, is taken as the source according to the so-called principle that the river only reaches far, the actual length of the Minjiang River is about 1280 km; Starting from the so-called "main stream" of the traditional east branch of Minjiang River, the total length of Minjiang River is only over 730 kilometers. According to the annual runoff, Dadu River is better, because it is said that more than 70% of the water in Minjiang River comes from the actual mainstream Dadu River.

As far as flow is concerned, Dadu River-Minjiang River is the largest tributary of the Yangtze River, Jialing River is the largest tributary of the Yangtze River Basin, and Hanshui River or Yalong River is the longest in the Yangtze River Basin.

However, traditionally, the importance of the east branch of Minjiang River is higher than that of Dadu River. As we all know, Sichuan, as one of the largest provinces in China (the fifth largest province), is roughly Sichuan Basin+Yunnan-Guizhou Plateau Marginal Belt+Western Sichuan Plateau. Although the proportion of Sichuan basin is not the highest, its importance is self-evident. For Sichuan, the status of Chengdu Plain goes without saying.

The east branch of Minjiang River just flows through Chengdu Plain and even many areas in Sichuan Basin, which just nourishes this fertile soil. Coupled with the restoration of water conservancy miracles such as Dujiangyan, this area is more vulnerable to floods and droughts. If it weren't for troubled times, there would be little hunger. Although there were massacres in the Yuan Dynasty and Qing Dynasty, so many people died, but they were always reborn in the ruins. In addition to immigration factors, it is also related to the unique natural conditions of the east branch of Minjiang River.

The Dadu River Basin is a high-risk area of geological disasters in China, with 22 12 potential geological disasters, mainly landslides and mudslides. Dadu River is rich in hydraulic theory, which can develop and install 23.368 million kilowatts. 1In May, 935, on the way to the Long March, the Chinese Red Army of Workers and Peasants crossed the Anshunchang Ferry in Shimian County and seized the Luding Bridge on the Dadu River in the west of Luding County. There are abundant tourist resources in the basin, and the famous Emei Mountain, Gongga Mountain, Hailuogou and Jinkou Grand Canyon all have unique tourist landscapes.

On the south bank of the middle reaches of Dadu River, the nearest county 1 1 km. It is a national 4A-level scenic spot, a national red tourism classic scenic spot and a famous historical and cultural town in Sichuan Province. An Shunchang Scenic Area has a wide Dadu River on one side and mountains on the other. Ancient residents scattered along these winding valleys and rivers, with blue walls and black tiles lined up.

Dadu River has always been a wild river. From the folk saying that "goose feathers sink to the bottom" to the famous sentence of "crossing the bridge and freezing iron", from the tragic battle of Emperor Qianlong in Jinchuan to the tragic story of Anshun Chang in wyndell dichinson, Shi Dakai is full of iron and blood. With the birth of 22 hydropower stations and the disappearance of the 500-kilometer canyon belt, perhaps all this will become an unforgettable history.

The Red Army crossed the Dadu River in the Long March of 1935. Forced crossing of the Dadu River refers to the forced crossing of the Dadu River in Anshunchang, Yuexi County, Sichuan Province (now Shimian County, Sichuan Province) in May, 1935, and it is also a famous battle on the way to the Long March.

He personally selected and led the seventeen warriors to cross the Dadu River, which opened a gap in the natural barrier that the enemy regarded as difficult to fly and opened a passage for the Central Red Army to go north.
