The source of the Yangtze River is where the source of the Yangtze River is

in Qinghai. Tuotuo River.

The Tuotuo River is the source of the Yangtze River. As early as in the Book of Shang, people were discussing the source of the Yangtze River, and Xu Xiake, a famous traveler in the Ming Dynasty, believed that the Jinsha River was the source of the Yangtze River, and wrote the book "Examination of the Source of the Yangtze River". In the Qing Dynasty, people thought that they knew the Tongtian River, but they still could not determine the source of the Yangtze River.

In 1956 and 1977, China inspected the headwaters of the Yangtze River twice, and in 1977, it was finally determined that the Tuotuo River, which originates in Geladandong, is the source of the Yangtze River.

It should be in the south.

When the Tuotuo River originates from the Jianggendiru Glacier of Geladandong, it is a small stream formed by the meltwater of some glaciers and cirques, the water surface is only 3 meters wide at this time, and the depth is only more than 20 centimeters, and then flows north through a distance of 9 kilometers, and the glacial meltwater of Gachadi Rugang Snow Mountain is collected at the foot of Badong Mountain, through a valley about 15 kilometers long, and continues to the north, it is divided into two small rivers with a width of 4 meters and 6 meters, and there are many dense cobweb-like water flows in the valleys on both sides of the river, which is the upper source of the Tuotuo River. At the exit of this valley, the valley suddenly cuts downward, forming a steep canyon about 5 kilometers long and more than 20 meters high.

After the river flows out of Badong Mountain, it first passes through a vast floodplain, then passes through a canyon, flows near Hulu Lake, and turns sharply to the east. After more than 130 kilometers of flow, the river becomes open, and by the time it reaches the Tuotuo River along the Qinghai-Tibet Highway, it is already a large river 3 meters deep and 20-60 meters wide.

The famous first bridge of the Yangtze River is on the beach along the Tuotuo River, which is 324 meters long; Reinforced concrete bridge with a width of 11 meters.

Tuotuo River continues to the east from here, to the confluence of Dangqu, Buqu and Duoerqu when it reaches Nangji Balong, it passes through 375 kilometers, forms a large river with a width of more than 30 meters here, and its name is Tongtian River from here.

The headwaters of the Yangtze River have changed.

Between the source of the Yangtze River and Yichang City, Hubei Province, it is the upper reaches, and there are many rapids; Yichang to Hukou County, Jiangxi Province is the middle reach, with developed meandering currents and many lakes (Poyang Lake is the largest, followed by Dongting Lake); The lake mouth is downstream to the estuary, the river is wide, and there is Chongming Island formed by the accumulation of water at the mouth of the river. The Yangtze River is rich in water volume and water conservancy resources, and in the peak water season, the 10,000-ton wheel can pass through Wuhan, and the small ferry can go up to Yibin. The Yangtze River basin is the most densely populated and economically prosperous region of Chinese.

In"Yangtze River"Under this general name, some sections of the river have their own names. This is one of the significant differences between the Yangtze River and the Yellow River. From the source of the Yangtze River to the mouth of the Dangqu River in the south of the Yangtze River, it is commonly known as the Tuotuo River, the source of the Yangtze River, with a length of 358 kilometers; From the mouth of the Dangqu River to the mouth of the Batang River in Yushu County, Qinghai Province, it is commonly known as the Tongtian River, with a length of 813 kilometers; From the mouth of the Batang River to the mouth of the Minjiang River in Yibin City, Sichuan Province, it is commonly known as the Jinsha River, with a length of 2,308 kilometers; From Yibin City to Nanjin Pass, Yichang City, Hubei Province, commonly known as the Sichuan River, the length is 1033 kilometers.

From Zhicheng, Yidu City, Hubei Province to Chenglingji, Yueyang City, Hunan Province, this section of the river is commonly known as Jingjiang River because it flows through the ancient Jingzhou area, with a length of 337 kilometers; "Thousands of miles of the Yangtze River, the danger is in the Jingjiang River"It refers to this section, which is also the first section of the Yangtze River to enter the plain area after flowing through the mountainous and hilly areas, and the second half of the Jingjiang River is known"No makeup"called. A section of the Yangtze River near Jiujiang City, Jiangxi Province, commonly known as Chengfu, is named after the ancient name of Xunyang in Jiujiang City. The Yangtze River in Zhenjiang and Yangzhou in Jiangsu Province was called the Yangtze River in ancient times, and was named after the Yangtze River ferry port leading to Zhenjiang City in the south of Yangzhou City.

In the last years of the Qing Dynasty, the gateway of the Yangtze River was forced to open under the imperialist gunboat policy, and foreign ships sailed up from Wusongkou to the Yangtze River"yangtze river", widely circulated.

The source of the Yangtze River is in Qinghai Province.

Analysis: The source of the Yangtze River - Geladandong Snow Mountain.

Heyuan The source of the Yangtze River has been said differently since ancient times. In some modern geographical works, there are roughly two theories about the source of the Yangtze River: one is that "the rivers originate from the same mountain", the Yangtze River and the Yellow River both originate from the Bayan Kala Mountain, the Yangtze River originates from the southern foothills, and the Yellow River originates from the northern foothills.

The other is that the Yangtze River originates in the Hoh Xil Mountains. There are two branches: the Mulu Wusu River in the south and the Chumar River in the north.

In the summer of 1976 and the summer of 1978, the Yangtze River Basin Planning Office organized two Jiangyuan investigation teams to conduct detailed field investigations in the Jiangyuan area to find out the water system and the source of the river. The upper source of the Yangtze River is located between Kunlun Mountain and Tanggula Mountain, where there are many rivers, the larger ones are Chumaer River, Tuotuo River and Dangqu 3. Among them, no matter the area of the river basin or the amount of water is the largest in Dangqu, Beizhi has determined that the Tuotuo River is the positive source according to the principle of "the source of the river is far away".

The south source is Dangqu, and the north source is the Chumar River. In the Jiangyuan area, there are more than 40 snow-capped mountains above 6,000 meters above sea level. The temperature is low, and the four seasons are like winter.

Annual precipitation is 200,400 mm, and snowfall is dominant. The average temperature in July is below 0, and only during the day under the strong radiation of the sun can the temperature reach above 0, and the trickle formed by the meltwater of ice and snow has become the initial source of water for the Yangtze River.
