How long is the Yangtze River? As the title suggests, thank you

6,300 kilometers The Yangtze River is 3,496 kilometers from Zhengyuan to Yibin, and 2,884 kilometers below Yibin, totaling 6,380 kilometers. Among them, the 80 kilometers shortened by the Jingjiang bend are subtracted, so the total length is 6,300 kilometers.

Recently, scientists remeasured the Yangtze River and found that it was 6,211,3 kilometers long, more than 80 kilometers shorter than the recognized 6,300 kilometers. However, this result has not changed the status of the Yangtze River as the longest river in Asia and the third longest river in the world.

In 2001, under the auspices of expert Liu Shaochuang, the Institute of Remote Sensing Application of the Chinese Academy of Sciences used satellite remote sensing images to measure and calculate, and the measurement results were accurate to two decimal places. The length of the Yangtze River was measured to be 6,300 kilometers. The research team used nearly 40 satellite images covering the main stream of the Yangtze River, and the satellite images were taken by the US Earth Resources Satellite with a resolution of 30 meters.

The calculation method is to measure the Yangtze River forward direction three times and reverse three times along the center line of the river channel, and the results are obtained after many computer calculations and geometric corrections. In this study, Dangqu is measured as the source of the Yangtze River, and the specific location of the source of Dangqu (multi-dynasty energy) is 94°30 44 east longitude, 32°36 14 north latitude, and 5170 meters above sea level.

Dangqu (from the source to Nangji Balong) kilometers, Tuotuo River kilometers, Tongtian River kilometers, Jinsha River kilometers, Yibin kilometers below, a total of kilometers. The average annual water inflow into the sea is more than 9600 billion cubic meters. The basin is between 24°30 35°45 north latitude and 90°33 112°25 east longitude.

It has a long history, giving birth to Chinese civilization, nurturing the Chinese nation, and nurturing generation after generation of the sons and daughters of the Chinese nation. It is one of the three birthplaces of ancient civilizations in the world.

The Yangtze River is the longest river in Asia, with a total length of 6,397 kilometers. It originates from the main peak of Tanggula Mountain on the Qinghai-Tibet Plateau. The Yangtze River is the third longest river in the world, after the Nile River in Africa and the Amazon River in South America, and the third largest river in the world.

The total area is 1,808,500 square kilometers (excluding the Huaihe River Basin), accounting for about 1.5 of the total land area of the country

The main stream of the Yangtze River, Yichang, is the upper reaches, with a length of 4,504 kilometers and a basin area of 1 million square kilometers, of which the Zhimen River is called the Jinsha River from Zhimen to Yibin, which is 3,464 kilometers long; The section of the Yibin to Yichang River is commonly known as the Sichuan River, which is 1040 kilometers long; Yichang to Hukou is the middle reach, with a length of 955 kilometers and a basin area of 680,000 square kilometers.

The Yangtze River is 3,496 kilometers from Zhengyuan to Yibin, and 2,884 kilometers below Yibin, totaling 6,380 kilometers. Among them, the 80 kilometers shortened by the Jingjiang River are subtracted, so the total length is 6,300 kilometers.

The length of the Yangtze River is 6,397 kilometers, which is the longest river in China, and it is predicted to be the second disaster river.

With a length of 6,397 kilometers, the Yangtze River is the longest river in China and the third longest river in the world.
