Introduction to Pearl River

In 2012, researchers from the Institute of Remote Sensing Application of the Chinese Academy of Sciences used satellite remote sensing technology to measure the length and basin area of the Pearl River, and obtained accurate data, and determined that the Pearl River is the second largest river in China. The annual runoff of the Pearl River is more than 330 billion cubic meters, ranking second in the country's river system, second only to the Yangtze River, 7 times the annual runoff of the Yellow River and 10 times that of the Huai River.

It has a total length of 2,320 kilometers and a basin area of 453,690 square kilometers (of which 442,100 square kilometers are in China and 11,590 square kilometers are in Vietnam. It is the largest river system in southern China and the third longest river in China.

The Pearl River water system is rich in water energy resources, and the famous hydropower hubs such as Tianshengqiao, Datengxia, Lubuge, and Xinfengjiang all belong to the Pearl River water system. The Pearl River Basin covers a vast area, mostly mountains and hills, accounting for the total area, while the plain area is small and scattered, only occupying, and the larger is the Pearl River Delta Plain. The Pearl River Basin is rich in tourism resources, and the famous Huangguoshu Waterfall and Guilin Mountains and Rivers are all in the Pearl River Basin.

The Pearl River is 2,320 kilometers long.

The Pearl River, also known as the Guangdong River.

It is the second largest river in China and the third longest river in China. The Pearl River originally refers to a 96-kilometer-long waterway from Guangzhou to the mouth of the sea, named because it flows through the famous Haizhu Island (stone), and later gradually became the Xijiang River and the Dongjiang River.

Bac Giang and the Pearl River Delta.

A general term for the rivers on it.

The Pearl River originates from the Yunnan-Guizhou Plateau.

The Umeng Mountains are the Maxiong Mountains, which flow through six provinces and regions in central and western China and northern Vietnam, and flow downstream into the South China Sea from eight estuaries.

There are 774 large and small rivers in the Pearl River water system, with a total length of more than 36,000 kilometers, abundant river water and numerous tributaries, which have brought superior conditions to the shipping industry of the Pearl River, and the shipping value is second only to the Yangtze River, ranking second in the country.

The regional extent of the Pearl River:

The Pearl River Basin is located between 21°31 and 26°49 north latitude and 102°14 and 115°53 east longitude. The basin starts from Nanling in the north to Yunwu, Yunkai, 60,000 mountains and 100,000 mountains in the south.

and other mountain ranges; From Lotus Mountain in the east.

To the west is the Umeng Mountain Range.

It is located in 6 provinces and regions including Yunnan, Guizhou, Guangxi, Guangdong, Hunan and Jiangxi, and the upper reaches of its secondary tributary, Zuojiang, are in Vietnam. The basin covers an area of 453,690 square kilometers, of which 10,000 square kilometers are in the domestic part, accounting for the total area of the country. The annual runoff is second only to the Yangtze River, and the length and basin area rank fourth in the country.

The length of the Pearl River is 2,320 km.

The average annual runoff in the Pearl River basin in Guangdong is 114.4 billion cubic meters. Among them: 25.1 billion cubic meters of the Dongjiang River, 45.7 billion cubic meters of the Beijiang River, 12.3 billion cubic meters of the main stream of the lower reaches of the Xijiang River, and 31.3 billion cubic meters of the Pearl River Delta.

The average annual runoff depth is mm, the average annual runoff depth is 800-1800 mm, and the average runoff coefficient is .

The runoff modulus of the Pearl River in Guangdong is liters and seconds per square kilometer, and the runoff modulus in various places is in liters and seconds per square kilometer. The coefficient of annual runoff variation is between; The absolute ratio of annual runoff is Dongjiang (Boluo Station), Beijiang (Shijiao Station) and Xijiang (Gaoyao Station).

Geomorphological features of the Pearl River:

The Pearl River Basin is mostly mountainous and hilly, accounting for the total area, while the plain area is small and scattered, and only occupies it. The general topography is high in the northwest and low in the southeast. In the northwest, there is the Yunnan-Guizhou Plateau with an average altitude of 1000 2000 meters, and there are basins and lakes on the plateau.

There are many rapids and waterfalls in the edge of the plateau, among which the Huangguoshu Waterfall on the Baishui River, the source of the Beipan River, is the most famous.

To the east of the Yunnan-Guizhou Plateau, there is a low mountain and hill with an altitude of about 500 meters, called Liangguang Hills. There are also many mountains with an altitude of 1,000 meters or more between the low hills, and there are many basins and valleys.

2320 km.

With a total length of 2,320 kilometers, the Pearl River is the third longest river in China, with an annual runoff of more than 330 billion cubic meters, ranking second in the country's river system.

With a total length of more than 2,300 kilometers, the Pearl River is the third longest river in China after the Yangtze River and the Yellow River. If the annual runoff is calculated, it is more than 330 billion cubic meters, six times that of the Yellow River, and the flow is only less than that of the Yangtze River.

The total length is 2400 km.

The Xijiang River, the main stream of the Pearl River, originates from the Maxiong Mountains in Zhanyi District, Qujing City, northeastern Yunnan Province, and flows through the four provinces (autonomous regions) of Yunnan, Guizhou, Guangxi, Guangdong, and the Hong Kong and Macao Special Administrative Regions. At the confluence of Sanshui and Beijiang in Guangdong, it flows into the South China Sea from eight estuaries in the Pearl River Delta region.

The Beijiang and Dongjiang river systems are almost all in Guangdong; The source of the Beijiang River is 582 kilometers long in the southern part of Hunan and Jiangxi provinces; The source of the Dongjiang River is 503 kilometers long in the southern part of Jiangxi Province. The Pearl River basin covers an area of 10,000 square kilometers in China, and more than 10,000 square kilometers in Vietnam. The Pearl River estuary alluvial forms the Pearl River Delta.

The Pearl River Basin is located between 102°14 -115°53 east longitude and 21°31 -26°49 north latitude. The area of mountains and hills in the basin is small, scattered and scattered, and only accounts for the whole basin, and the largest plain is the plain of the Pearl River Delta. The topography of the whole basin is generally high in the northwest and low in the southeast.

The northwest is the Yunnan-Guizhou Plateau and the edge of the Qinghai-Tibet Plateau, and there are many rapids and waterfalls in the upper reaches of the Xijiang River, among which the Huangguoshu Waterfall on the Baishui River is the most famous. To the east of the Yunnan-Guizhou Plateau, there are mainly low hills (i.e., Liangguang hills). The alluvial plain in the lower reaches of the Pearl River is the famous Pearl River Delta, where rivers and seas meet and the river network is intertwined, with the unique style of a southern water town.

Characteristics of the water system. In the Pearl River system of Guangdong, the Dongjiang River, the Liuxi River and the Beijiang River flow roughly from northeast to southwest, and the Xijiang River and Tanjiang River flow roughly from west to east, and all converge in the Pearl River Delta network river area, and finally flow into the South China Sea by 8 major gates respectively, and the whole water system is a fan-shaped water system.

The topography of the Pearl River Basin in Guangdong is roughly inclined from north to south, and the highest peak, Shikenggang, is 1,902 meters above sea level. The area of the left bank of the main stream of the Pearl River is more than twice that of the right bank. The density of the river network is relatively large, and the density of the river network in the delta area is more than one kilometer per kilometer.

The bending coefficient of the main stream is that the main stream is a flat river.
