Which river in China is called the golden waterway?

The Yangtze River originates from the "roof of the world" of the Tanggula Mountains on the Qinghai-Tibet Plateau-southwest of Dongfeng, and is the mother river of the Chinese nation. The main stream of the Yangtze River runs through central China from west to east. Hundreds of tributaries converge north and south, extending to Qinghai, Sichuan, Tibet, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Shanghai and other provinces and regions. The drainage area is 6.5438+0.8 million square kilometers, accounting for about 20% of the total land area of China. Most of the water in the Huaihe River also flows into the Yangtze River through the Grand Canal.

Above Yichang, the main stream of the Yangtze River, is upstream, with a length of 4,504 kilometers and a drainage area of 6,543.8+0,000 square kilometers, of which the branch from Zhimen to Yibin is called Jinsha River, with a length of 3,464 kilometers. Yibin-Yichang section, commonly known as Chuanjiang, is 1040 km long. Yichang to Hukou is the middle reaches, with a total length of 955 kilometers and a drainage area of 680,000 square kilometers. Hukou to the sea mouth is downstream, 938 kilometers long, with a drainage area of 6,543,800 square kilometers.

Jacky on the Yangtze River is a vast geographical unit, including the vast area between Kunlun Mountain and Tanggula Mountain. It is about 400 kilometers long from east to west and 300 kilometers wide from north to south, with a total area of over 654.38+ 10,000 square kilometers. The terrain in the area is gentle, with an average elevation of 4,400-4,700 meters, the annual average temperature is below -4℃, the temperature is low, the vegetation is sparse, the frozen soil is widely distributed, and the animal species are simple, most of which are endemic to the plateau, including wild donkeys, white-lipped deer, bison, snow leopards, Tibetan antelopes, brown bears, wolves and green sheep. The source of the Yangtze River consists of Chuma River in the north, Dangqu River in the south and Tuotuo River in Jacky. Chumar River originates from Lake Hoh Xil in the depth of Hoh Xil Nature Reserve, which means "Hongshui River" in Tibetan, with a total length of about 5 15 km and a small flow. The source is often cut off in summer and finally flows into the Tongtian River in the upper reaches of the Yangtze River.
