What are the seven major river basins in China?

The seven major water systems in China are: Pearl River, Yangtze River, Yellow River, Huaihe River, Liaohe River, Haihe River and Songhua River.

1, Yangtze River system

The Yangtze River originates from Tanggula Mountain on the Qinghai-Tibet Plateau. It is the third largest river in the world and the largest river in China, with a total length of 6397KM and the third largest river volume in the world.

The Yangtze River flows through Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Shanghai 1 1 provinces and cities, and flows into the East China Sea east of Chongming Island in Shanghai. As a unique river in China, the Yangtze River is rich in water resources, especially shipping, and the navigable mileage accounts for 70% of the navigable mileage of inland navigation in China.

In addition, there are many tributaries of the Yangtze River, among which Jialing River, Wujiang River, Minjiang River, Xiangjiang River, Ganjiang River and Hanjiang River are famous.

2. Yellow River system

The Yellow River originates from Zhaqu in Bayan Kara Mountains of Qinghai-Tibet Plateau. It is the second largest river in China, the "mother river" of China and the main birthplace of Chinese civilization. Because the Yellow River carries a lot of sediment, the river is often golden yellow, so it is named "Yellow River".

The Yellow River, with a total length of 5,464 kilometers, flows through nine provinces and cities including Qinghai, Gansu, Sichuan, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong, and finally flows into the Bohai Sea, the largest inland sea in China.

3. Pearl River system

The Pearl River, also known as the Yuejiang River, is the third largest river in China and the second largest river after the Yangtze River in terms of water volume and shipping value. The Pearl River, with a total length of 2,320 kilometers, originated in Yunnan-Guizhou Plateau and finally flowed into the South China Sea. The Pearl River system is developed, with high shipping value and tourism value. The famous Huangguoshu Waterfall and Guilin landscape all belong to the Pearl River Basin.

4. Huaihe River System

Huaihe River originated in Nanyang City, Henan Province, the ancient city of Huaishui. It is a river between the Yangtze River and the Yellow River, flowing through Henan, Anhui and Jiangsu provinces, with a total length of 100KM.

Huaihe River is of great significance in the geographical distribution of China. Qinling-Huaihe line is the main dividing line between north and south of China, which is the 0℃ isotherm position of 65438+ 10 and the 800mm isoprecipitation line, and also the dividing line between subtropical monsoon climate and temperate monsoon climate.

5. Haihe River System

Haihe River is the largest water system in northern China and one of the seven major rivers in China. The main stream of the Haihe River, also known as the ancient river, originated in Tianjin and flowed into the Bohai Sea at Dagukou. Haihe River Basin mainly flows through Hebei, Beijing, Tianjin, Shandong and other provinces.

6. Songhua River system

Songhua River has two sources: Nenjiang River in the north, which originates from Ilhuli Mountain, a branch of Daxing 'anling, and Songhua River in Liu Xi in the south, which originates from Tianchi Lake in Changbai Mountain. It is the largest river in Heilongjiang Province, China, which spans the four provinces of Northeast China, Liaoning, Jilin, Inner Mongolia and Heilongjiang, and is the most important river in Northeast China.

7. Liaohe River System

Liao River, a river in the south-east of China, was called Da Liao River in Han Dynasty and Liao River after Five Dynasties. Liaohe River flows through Inner Mongolia, Hebei, Jilin and Liaoning provinces, with a total length of 1345KM, and flows into Bohai Sea.

Extended data

The Yangtze River has a huge water system. The mighty main stream of the Yangtze River has more than 700 tributaries along the way, running through the north and south, forming a vast area that flows through more than 654.38+08,000 square kilometers, accounting for 654.38+08.8% of the total area of China.

The main tributaries of the Yangtze River are Yalong River, Minjiang River, Jialing River, Wujiang River, Yuanjiang River, Hanjiang River and Ganjiang River, with average flow above 1000 m3/s (all exceeding the Yellow River). Among them, the Jialing River basin has the largest area, with10.6 million square kilometers. The longest length of Hanjiang River is 1577 km. Minjiang River is the most abundant, accounting for 87.7 billion cubic meters.

Most areas of the Yangtze River Basin are located in the subtropical monsoon climate zone, which is warm and humid. The average annual precipitation is 1 100 mm, and the average annual discharge into the sea is nearly 1 trillion cubic meters, accounting for about 36% of the river runoff in China, equivalent to 20 Yellow Rivers.
