Where does the Yangtze River originate, and where does the Yangtze River originate?

The Yangtze River originated from the Yanshan movement in the Jurassic period hundreds of millions of years ago, forming the Tanggula Mountains in the upper reaches of the Yangtze River, and the Qinghai-Tibet Plateau was slowly raised, forming many high mountains and deep valleys, depressions and rift valleys. 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. 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, the strong Himalayan movement, the uplift of the Qinghai-Tibet Plateau, the disappearance of the ancient Mediterranean, and the general intermittent rise of the Yangtze River basin.

The degree of its rise is moderate in the east and sharp in the west. The high mountains on both sides of the Jinsha River protruded, and the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau were significantly uplifted, and some fault basins were formed at the same time. The strong downward cutting of the river has led to the emergence of many deep and steep canyons, and the water systems that originally flowed from north to south merged with each other and flowed eastward.

The middle and lower reaches of the Yangtze River rise slightly, forming middle and low mountains and hills, and the low depression areas sink into plains (such as the Lianghu Plain, Nanxiang Plain, Duyang Plain, Suzhou-Anhui Plain, etc.). By 3 million years ago, the Himalayas were strongly uplifted, and the western part of the Yangtze River basin was further uplifted. The erosion of the ancient Yangtze River extending from Hubei to the Sichuan Basin has accelerated, cutting through Wushan, connecting the eastern and western ancient Yangtze River, and merging the Min River and Jinsha River in Yibin, Sichuan Province into the Yangtze River.

The river flows into the East China Sea, and today's Yangtze River is formed.

The Yangtze River originates in the Jianggendiru Glacier in the Tanggula Mountains of the Tanggula Mountains and the Dandong Snow Mountains of Qinghai Province, China.

The source of the Yangtze River is located in the belly of the Qinghai-Tibet Plateau, and the source mainly consists of three branches: Tuotuo River, Dangqu River and Chumaer River, of which Tuotuo River is the 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. After passing through snow-capped mountains and valleys, out of the Tanggula Mountains.

It flows northward, cuts through the lower hills of the Zulken Ula Mountain, and flows eastward near Hulu Lake to the capsule.

After receiving the tributary of the right bank near Balong, it is followed by the Tongtian River. Tongtian River from Dangqukou to Qing.

The Batang estuary in Yushu County, Hai Province, is 813 kilometers long.

It originated from the main peak of the Tanggula Mountains on the Qinghai-Tibet Plateau.

The source of the Yangtze River is Tanggula Mountain.

The source of the Yangtze River is in Mafei Jiri Township, Amdo County, Qinghai Province. The Yangtze River originates from the Gradan Winter Snow Mountain, the main peak of the Tanggula Mountains in the southern part of Qinghai Province, and its source is the Tuotuo River. Gradandong Snow Mountain is located in Mafei Jiri Township, Amdo County, Qinghai Province.

It is generally believed that the Tuotuo River is the source of the Yangtze River, and the main streams of the Yangtze River start from the Tuotuo River to the downstream are the Tongtian River, the Jinsha River, the Sichuan River, the Jing River and the Yangtze River. The Yangtze River has a huge amount of water and a large topographic difference in the middle and upper reaches of the Yangtze River, which is suitable for hydropower development and is the "hydropower base" of China. The middle and lower reaches of the region are flat and suitable for shipping development, and are China's "best waterway".

The amount of water in the Yangtze River

The Yangtze River is the most abundant river in China, with a total water resource of 961.6 billion cubic meters, accounting for about 36% of the country's total river runoff and 20 times that of the Yellow River. It ranks third in the world after the Amazon River and the Congo River (Zaire) in the equatorial rainforest. The Paraná-La Plata River in South America and the Mississippi River in North America, which are similar to the latitude zone of the Yangtze River basin, have far less water than the Yangtze River, the former being about 70% of the Yangtze River and the latter about 60% of the Yangtze River.

Due to the large population of the basin, the per capita water share is 2,760 cubic meters, which is only 1 4 of the world's per capita share. The characteristics of water resources in the Yangtze River are mainly reflected in the temporal and spatial distribution of river runoff, and the surface water resources in the basin account for 99% of the total water resources. River runoff accounts for more than 96% of surface water resources. River runoff during the flood season generally accounts for 70% to 75% of the annual runoff.

The regional distribution of runoff is also uneven, with the Jinsha River and Hanjiang River systems being the least water producers, and the Poyang Lake and Dongting Lake systems being the largest.

The Yangtze River originates from the main peak of Tanggula Mountain on the Qinghai-Tibet PlateauIt includes a vast area between the Kunlun Mountains and the Tanggula Mountains, with a length of about 400 kilometers from east to west and a width of about 300 kilometers from north to south, with a total area of more than 100,000 square kilometers.

The water system in the source area of the Yangtze River is mainly composed of the Chumar River water system of the north branch, the Tuoluo Tuoyuan Tuo River water system of the west branch, and the Dangqu water system of the south branch. Regarding the controversy about the source of the Yangtze River, in 1976, the scientific expedition believed that the Tuotuo River in the west was the source of the Yangtze River.

In 2008, according to the calculations of remote sensing satellites and the measurements of several expeditions, the southern source of the Yangtze River is the longest in Dangqu, the largest basin area, and the largest water volume among the sources of the Yangtze River. Dangqu originates from the alpine swamp at the eastern foot of Xiasheri Abashan Mountain in the eastern section of Tanggula Mountain, and is the true source of the Yangtze River.

Climatic characteristics:

The Yangtze River basin has a warm climate with abundant rainfall, and has a variety of climate types due to its vast territory and great changes in topography. Natural disasters such as floods, floods, droughts, and hailstorms also occur frequently. The middle and lower reaches of the Yangtze River have four distinct seasons, cold in winter and hot in summer, with an average annual temperature of 16 18, the maximum atmospheric temperature in summer is about 40, and the lowest temperature in winter is about minus 4.

The climate of the Sichuan Basin is mild, and the winter temperature is about 5 more than that of the middle and lower reaches. The area around Kunming is like spring all year round. In the Jinsha River Gorge area, it presents a typical three-dimensional climate, the top of the mountain is covered with snow, and the four seasons are like spring after the mountain chaos.

The Jiangyuan area has a typical alpine climate, with an average annual temperature, four seasons such as winter, dry, low air pressure, long sunshine and many hail and strong winds.

1. The Yangtze River originates from the southwest side of the Tanggula Mountains in the Qinghai-Tibet Plateau of Qinghai Province, the Geladan Winter Peak is a snow-capped mountain group, with an altitude of 6,621 meters, covering an area of 670 square kilometers covered by ice and snow, and there are more than 20 peaks of more than 6,000 meters around, and numerous glacier meltwater forms streams, which converge into a large area of swamp area, forming lakes scattered all over the place, and these lakes and swamps are the source of life of the Yangtze River.

2. The water system in the source area of the Yangtze River is mainly composed of the water system of the Chumar River in the north branch, the water system of the Tuotuo River in the west branch, and the Dangqu water system in the south branch of the Yangtze River.
