The main stream of the Yangtze River runs through central China from west to east. Hundreds of tributaries converge north and south, extending to parts of eight provinces, including Guizhou, Gansu, Shaanxi, Henan, Guangxi, Guangdong, Zhejiang and Fujian. The drainage area is 6.5438+0.8 million square kilometers, accounting for 654.38+0/5 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.
Extended data:
First, the source of the Yangtze River.
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.
Second, tributaries
The Yangtze River system is developed and consists of thousands of tributaries, of which the basin area is 1000km? There are 437 tributaries above, 49 tributaries above 1 1,000 square kilometers and 8 tributaries above 80,000 square kilometers.
Among them, the areas of Yalong River, Minjiang River, Jialing River and Hanjiang River all exceed 654.38+ 10,000 square kilometers. The tributary basin of Jialing River has the largest area, the annual runoff and average annual discharge of Minjiang River are the largest, and the length of Hanjiang River is the longest.
