What are the names of rivers in our country?

In addition to the Yangtze River and the Yellow River, several major Chinese rivers:

1. Heilongjiang is the boundary river between China and Russia, and it is also the longest river in China. The oldest name in Heilongjiang is "Heishui". The Northeast is the famous black soil of our country, the river flows in the black riverbed, and it looks black from afar, hence the name.

And because the "black river" flows endlessly in the crooked riverbed, like a swimming dragon, so people call it "black dragon."

2, the Jinsha River is the upper reaches of the Yangtze River, the Red Army's Long March once passed here, *** later also wrote a heroic poem: "Jinsha water beats the clouds and cliffs warm, and the Dadu Bridge crosses the iron cable and ...... cold.""The Jinsha River, known as Lishui in ancient times, is the upper reaches of the Yangtze River, originating in the middle of the Tanggula Mountains on the Qinghai-Tibet Plateau, and is named after the abundant Jinsha in ancient times. According to Song Yingxing's "Heavenly Creations", it contains:

The gold is more out of the Jinsha River in Yunnan (the ancient name of Lishui), this water source comes out of Tubo, around the Lijiang Mansion, as for the North Shengzhou, more than 500 miles of the loop, there are several gold withdrawals. ”

3. The name of "Yangtze River" was first seen in the Sui Dynasty, referring to the area of Yizheng and Yangzhou in the lower reaches of the Yangtze River. In modern times, the Yangtze River in the lower reaches of the Yangtze River was a prosperous place in China, and Western missionaries were the first to arrive in China. For Western missionaries, the Yangtze River is the Yangtze River.

Therefore, in foreign languages, "Yangtze River" refers to the entire Yangtze River.

4. The Huangpu River is the mother river of Shanghai and an important cultural symbol of Shanghai, which has precipitated the history of Shanghai, witnessed the ups and downs of Shanghai, nurtured the prosperity of Shanghai, and is closely connected and inseparable from Shanghai. Shanghai was a territory of Chu during the Warring States Period. In the first year of King Chu Kaolie (262 B.C.), he worshiped Huang Xie as the prime minister, and was named Chun Shenjun, and the area around Shanghai was his fief.

It was a desolate place from where a river flowed into the sea. Every time it rains heavily, the river floods, and people suffer greatly. According to legend, Huang Xie led the people to dredge and control it, so that it poured into the East China Sea.

Since then, people on both sides of the river have lived and worked in peace and contentment, and this river has been called "Huangxiepu", also known as "Huangpu River". Pu originally referred to the place near the water, and by extension, it referred to the flow of water.

5. The Qiantang River is the largest river in Zhejiang Province, flowing through Hangzhou City, flowing into Hangzhou Bay from west to east and into the East China Sea. The Qin Dynasty was in Qiantang County, west of present-day Hangzhou. In the Tang Dynasty, "Tang" was the name of the country, and "soil" was added as "Tang". The Qiantang River got its name because it flows through Qiantang County.

The name of the river in our country is rivers, lakes and seas, and the more famous ones in ancient times have heard of weak water. Weak water, the name of the river, in ancient myths and legends, called the treacherous and difficult to cross the river and sea. "The Story of the Ten Continents in the Sea: Fenglin Continent":

Fenglin Island is in the West Sea, the place is 1,500 miles, there is weak water around the continent on all sides, the feathers do not float, can not be crossed. "Generally refers to dangerous and distant rivers, and is commonly used"Three thousand weak water, take only one scoop to drink", expressing single-mindedness towards love. Because the waterway is shallow or the local people are not accustomed to building boats and do not use boats, only use rafts to cross, the ancients often think that the water is weak and cannot carry boats, because it is called weak water.

Therefore, in ancient times, there were many people who called weak water. "Shu Yu Gong":"The black water west river is only Yongzhou, and the weak water is both west.

Again:"The weak water is directed to Heli, and the remaining waves enter the quicksand. "The upper source refers to the Shandan River in Gansu today, and the downstream is the Heihe River after the confluence of the Shandan River and the Ganzhou River, and after entering the territory of Inner Mongolia, it is called the Ejina River.

Weak water is also another name for the section of China's Heihe River from Dingxin in Jinta County to Xixin Village in Ejinaqi Lake.

Another name for river water: Chuan, Qingmiao, trickle, Biyuan.

River water contains dissolved substances such as carbonates, sulfates and calcium, and unlike seawater, which mainly contains chloride and sodium. The physical properties of river water mainly refer to the temperature, color, transparency, smell and taste of the water. The chemical properties are determined by the amount of gases, ions, molecules, colloidal substances and suspended solids, microorganisms and these substances dissolved and dispersed in river water.

The main factors affecting the water quality of the river are the recharge of the river water**, hydroclimatic factors, rock, soil, vegetation conditions and human activities in the basin. Due to the cold climate and slow chemical process, the meltwater only dissolves and leachs salt from the surface soil, and the salinity of the river water is low.

The river water recharged by groundwater has a high degree of salinity due to the close contact between groundwater and soil and rock for a long time, and more dissolved components are leached from it. The river water mainly recharged by rainwater is collected in the channel through surface runoff, which is greatly affected by the climate and soil cover of the basin, and the salinity is generally between the river water recharged by ice and snow melt water and the river water recharged by groundwater.

The state of movement of the river.

Laminar flow: all water flows are in parallel beam motion, that is, the trajectory lines (streamlines) of the water quality point movement are parallel, the direction of movement in the water flow is consistent, and the flow velocity is uniform;

Turbulence: The speed and direction of movement of each water quality point in the flow changes at any time and place, and the change beats up and down around an average value.

The flow of natural rivers is generally turbulent.

China is one of the countries with the most rivers in the world. China has many great rivers with long history. Among them, there are more than 1,500 rivers with a basin area of more than 1,000 square kilometers.

China's rivers follow the cycle of river runoff, including outflow rivers that flow into the ocean, and internal rivers that do not communicate with the ocean. The most famous are the Yangtze River, the Pearl River, the Yellow River, the Heilongjiang River, the Songhua River, the Liao River, the Brahmaputra River, the Lancang River, the Nu River, and the Han River.

Then the boundaries of the upper, middle and lower reaches of the Yellow River are: Hekou Town, Tuoketuo County, Inner Mongolia Autonomous Region, and Mengjin County, Luoyang City, Henan Province.

1. The section of the Yellow River above Hekou Town, Tuoketuo County, Inner Mongolia Autonomous Region is the upper reaches of the Yellow River;

2. The section of the Yellow River between Hekou Town, Tuoketuo County, Inner Mongolia Autonomous Region, and Mengjin County, Luoyang City, Henan Province is the middle reaches of the Yellow River;

3. The section of the Yellow River below Mengjin County, Luoyang City, Henan Province is the lower reaches of the Yellow River.

The Yellow River is 5,464 kilometers long and is the second largest river in China. For the Yellow River, it is divided into upper, middle and lower reaches according to the natural environment and hydrological conditions of the area through which the river flows. The upper reaches of the Yellow River are 346 kilometers long, from the source of the river to the Inner Mongolia Autonomous Region, the river crosses the Qinghai-Tibet Plateau and flows through gorges, with more than 20 famous canyons scattered in between.

The mountains here are steep and steep, with large drops, and rich water resources. The hydrological characteristics of this section are more water and less sand, the river water is relatively clear, and the flow is uniform. After the Yellow River flows out of the Qingtong Gorge, its terrain is flat and open, entering the Ningxia Plain and the Hetao Plain of Inner Mongolia.

It is crisscrossed by canals and has become one of the earliest agricultural development zones in the upper reaches of the Yellow River. The middle reaches of the Yellow River are 1,234 kilometers from Shenhe, from Hekou Town in Tuoketuo County, Inner Mongolia Autonomous Region to Taohuayu in Zhengzhou, Henan.

The hydrological characteristics of this section of the river: due to the heavy rain in summer and autumn, the sand source is abundant, the water is sandy, the peak flow is large, and the sediment content is high, and it has become a world-famous sandy river. Siltation and erosion of the river channel alternate with canyons and wide valleys.

The lower reaches of the Yellow River are 767 kilometers, from Taohuayu in Zhengzhou, Henan Province to Kenli County, Shandong Province, and flow through the North China Plain from west to east.

The slope of the river is small and the water flow is gentle. In addition, the river channel is wide and shallow, the sediment is seriously silted, the riverbed is gradually raised, and the banks are almost completely protected by embankments. The beach surface of the river is generally about 2-5 meters higher than the ground on both banks, and some are as high as 10 meters of the sedan chair, which is the world's famous "hanging river".

The main rivers of our country are as follows:

Outflow rivers: the Yangtze River, the Yellow River, the Heilongjiang River, the Pearl River, the Liao River, the Hai River, the Huai River, etc., flow eastward into the Pacific Ocean; The Brahmaputra River flows eastward out of the country and then southward into the Indian Ocean; The Irtysh River in Xinjiang flows northward into the Arctic Ocean.

Neiliu River: Neiliu River, Tarim River, Ili River in southern Xinjiang, etc.

The source of the Yangtze River is a broad geographical unit, which includes a vast area between Kunshan and Tanggula Mountains, with a length of about 400 kilometers from east to west and a width of about 300 kilometers from north to south, with a total area of more than 100,000 square kilometers. The terrain in the area is gently undulating, with an average altitude of 4,400-4,700 meters and an average annual temperature of -4°C.

The Yellow River originates from the ancient Zongliequ (another version is Kariqu) at the northern foot of Bayan Kala Mountain"It is an oval-shaped basin with a length of 40 kilometers from east to west and a width of about 60 kilometers from north to south, with more than 100 small water pools, like stars and crystalline pearls.

The Xijiang River, the main stream of the Pearl River, originates from the foothills of Maxiong Mountain, Zhanyi County, Qujing City, Yunnan Province. Maxiong Mountain is the watershed of the Shenglan River, the Nanpan River and the Beipan River, and is the source of the Pearl River, with an altitude of 2,444 meters.

Heilongjiang has two origins, the south source is the Ergun River in the Inner Mongolia Autonomous Region of China, the north source is the Mongolian People's Republic, the Emin River in Russia, the Shilka River, the two rivers meet at the foot of the En and Hada Mountains, and are called Heilongjiang. The source of the Ergun River is the Krulun River, which originates in the Kent Mountains of Mongolia, and the Hailar River, which originates from the Kuril Mountains and the Camel's Neck Mountains.

Among the three sources of the Brahmaputra River, the northern source of the Mayumu Zangbo originates from the southern foothills of the Gangdis Mountains, the middle source is the Jemayangzong Glacier at an altitude of 5,590 meters in the northern foothills of the Himalayas, and the southern source Kubi Zangbo originates from the Asejiago Glacier at the northern foot of the Himalayas.
