The Formation of the Yangtze River Where is the source of the Yangtze River?

The geological process of the formation of the Yangtze River: (quoted from the encyclopedia, with deletions).

The Yangtze River originated from the Yanshan movement in the Jurassic period 100 million years ago, forming the Tanggula Mountains in the upper reaches of the Yangtze River, and the Qinghai-Tibet Plateau was slowly elevated. The middle and lower reaches of the Yangtze River, the Dabie Mountains and the Wushan Mountains between Sichuan and Hubei were uplifted, the Sichuan Basin was sagging, and the ancient Mediterranean Sea retreated further to the west. At this time, the flowing water from Tanggula Mountain and the west side of Wushan Mountain flowed into the ancient lake or ancient Mediterranean Sea in the Sichuan Basin, and the flowing water on the east side of Wushan Mountain flowed into the Pacific Ocean.

100 million years ago in the Cretaceous period. The Sichuan Basin is slowly rising. The razing effect continued to develop, and the Yunmeng and Dongting basins continued to sink.

In the Eocene, 30 million to 40 million years ago, a strong Himalayan movement occurred, the Himalayas and Hengduan Mountains were formed, the ancient Mediterranean Sea disappeared, and the western part of the Yangtze River basin was strongly uplifted. Due to the disappearance of the estuary, the Sichuan Basin formed vast lakes that took over the nearby water system. The rise in the middle and lower reaches of the Yangtze River is small, and the low depression area sinks into plains (such as the Lianghu Plain, Poyang Lake Plain, Suzhou-Anhui Plain, etc.).

With the strong uplift of the Himalayas, the western part of the Yangtze River basin is further uplifted. The erosion of the ancient Yangtze River from Hubei to the four basins accelerated, and finally cut through Wushan about 3 million years ago, the ancient Sichuan Lake disappeared, and the ancient Yangtze River in the east and west was connected, and the river water was mighty and poured into the East China Sea, and today's Yangtze River was formed.

The source of the Yangtze River is in the Dandong Snow Peak.

The source is under the main peak of the Tanggula Mountains, the Geladan Winter Peak, Jiang Gendi is like a glacier ice and snow meltwater.

1. The origin of the Yangtze River is on the southwest side of Geladan Winter Peak in the Tanggula Mountains of the Qinghai-Tibet Plateau, ending at Chongming Island in Shanghai and flowing into the East China Sea.

2. The Yangtze River, the longest river in Asia and the third longest river in the world, is the longest river in the world with a total length of 6,387 kilometers. The Yangtze River originates from the southwest side of Geladan Dongfeng in the Tanggula Mountains of the Qinghai-Tibet Plateau, the "roof of the world", and the water system in the source area of the Yangtze River is mainly composed of the Chumar River in the north branch, the Tuotuo River in the west branch, and the Dangqu water system in the south branch.

The source of the Yangtze River is located in the belly of the Qinghai-Tibet Plateau, and its headwaters mainly include the Tuotuo River, the Dangqu River and the Chumar River, of which the Tuotuo River is the main source of the Yangtze River. With a total length of 358 kilometers, the Tuotuo River originates from the main peak of the Tanggula Mountains, and is 6,621 meters above sea level on the southwest side of the Geladan Winter Snow Mountain.

First, the source introductionThe Yangtze River has three sources, the southern source is Dangqu, the northern source is the Chumaer River, and the western source is the Tuotuo River. Nanyuan Dangqu, which originates from the alpine swamp at the eastern foot of Xiasheri Abashan Mountain in the eastern section of Tanggula Mountain, is the real source of the Yangtze River. With a length of kilometers and a basin area of 30,219 square kilometers, the river volume is the largest among the headwaters of the Yangtze River, according to the calculations of remote sensing satellites and the measurements of several expeditions, and its length is the highest among the rivers at the source of the Yangtze River.

2. Tuotuo RiverThe Tuotuo River is the western 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". By the Qing Dynasty, people had recognized the Tongtian River, but they still could not determine the source of the Yangtze River.

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