What rivers are there in Lijiang?

For big rivers, there is the Jinsha River. For small rivers, there are many. There are many lakes along the Jinsha River. There are more lakes in Lijiang. There is the Donggan River Plateau Wetland in Lijiang City. What rivers are there in Diyuan Park, Lashihai, Wenbihai, and the famous Lugu Lake in Jiangnan?

There are about 100,000 rivers in our country. The main outflow rivers. The upper reaches of China's main outflow rivers are almost all in ethnic minority areas. , except for some rivers in the northeast and southwest, the flow direction is controlled by the general trend of China's terrain, which is higher in the west and lower in the east. Most of the trunk streams flow from west to east. Most of the trunk streams of outflow rivers originate from three major step uplift belts: the first zone is The eastern and southern edges of the Qinghai-Tibet Plateau. Giant rivers with long history are developed here, such as the Yangtze River, Yellow River, Lancang River, Nu River, Yarlung Zangbo River, etc. These rivers are not only the famous Changchuan River in our country, but also the largest rivers in the world, many international Sexual rivers, such as the Salween River (upper source Nujiang River) that flows through Myanmar; the Mekong River (upper source Lancang River) that flows through Laos, Myanmar, Thailand, Cambodia, and Vietnam and then enters the sea; the Brahmaputra flowing through India The Indus River (the upper source of the Yarlung Zangbo River) and the Indus River (the upper source of the Shiquan River) also originate here. The second zone is the uplift zone originating from the edge of the second ladder, that is, the Greater Khingan Range, the Hebei-Jinshan Mountains and the Yunnan-Guizhou Plateau, such as Heilongjiang, The Liaohe River, Haihe River, Xijiang River, etc. are also important rivers. The third zone is the Changbai Mountains, mainly the Tumen River and the Yalu River. They are close to the ocean, have short flows, large gaps, and rich hydraulic resources.

(1) Heilongjiang. Heilongjiang meanders on the border of northeastern China. It is an international river. Due to the large amount of humus dissolved in the water, the water color is dark, like a rushing dragon, so it is named - Heilongjiang, or Saharian Ula in Manchu. , which means black water.

Heilongjiang has two sources, the Ergun River in the south and the Shilka River in the north. The two sources originate from the mouth of the Dasilovka River and are called Heilongjiang after they merge. It flows eastward and finally flows into the Sea of ??Okhotsk and the Tatar Strait near Nikolayevsk (Temple Street) in the former Soviet Union. Starting from the source of the Hailar River, Heilongjiang has a total length of 4,370 kilometers and a drainage area of ??1.62 million square kilometers. It is the largest river in the world One of the ten giant rivers, the Ergun River Basin belongs to the source area of ??Heilongjiang. The Hailar River runs through the Hulunbuir League of Mongolia from east to west, with a length of 620 kilometers. It is called the Ergun River when it reaches the bottom of Abagai. The main stream of the Guna River is 900 kilometers long, and its right bank belongs to the Inner Mongolia Autonomous Region. In addition to the Hailar River, the larger tributaries include the Gen River, the Belz River, etc. The drainage area is about 116,000 square kilometers each.

There are more than 200 tributaries of Heilongjiang, among which the Songhua River is the longest. The Songhua River also has two sources, the north and the south. The south source originates from Tianchi in Changbai Mountain in Yanbian Korean Autonomous Prefecture, Jilin Province; the Mudanjiang River originates from Mudanling in Yanbian, passes through Dunhua City, and finally ends in Yilan County in Heilongjiang Province merges into the Songhua River.

The Nenjiang River, the northern source of the Songhua River, is the largest river in eastern Inner Mongolia. It runs through the eastern edge of the Hulunbuir League and the Xing'an League from north to south, and originates from the Yilhuri Mountains, a branch of the Greater Khingan Mountains. The southern slope of the Nenjiang River. The total drainage area is 282,000 square kilometers. The drainage area in Inner Mongolia is nearly 150,000 square kilometers, and most of it is located on the west bank of the Nenjiang River. The Nenjiang River is the transit water in Inner Mongolia second only to the Yellow River in the west. The average annual runoff is 21.96 billion cubic meters.

(2) Yellow River. The Yellow River is the second largest river in China and one of the famous rivers in the world. The Yellow River originates from the foot of Gezungeya Mountain at the northern foot of Bayan Har Mountain in Qinghai Province. The Kariqu flows through nine provinces and regions, including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan, and Shandong, and flows into the Bohai Sea in Kenli County, Shandong Province. It has a total length of 5,464 kilometers and a drainage area of ??750,000 square kilometers.

The upper reaches of the Yellow River are from the source to Hekou Town, Tuoketuo County, Inner Mongolia; the middle reaches are from Hekou Town to Mengjin, Henan Province; and the lower reaches are from Mengjin to the estuary. The upper reaches of the Yellow River are 3,472 kilometers long. Most areas of the upper reaches of the Yellow River Located in ethnic minority areas, the upper reaches of the Yellow River have very different river channels and hydrological characteristics than the middle and lower reaches.

The upper reaches of the Yellow River can be divided into river source sections, canyon sections and alluvial plains based on different river channel characteristics. and other three parts. Heyuan section

Starting from Kariqu, it passes through Xingxiu Sea, Zhaling Lake, and Eling Lake to Longyang Gorge in Guide. Most of the river source section flows on a plateau of 3,000--4,000 meters. The river is winding, and there are many lakes and swamps in the two rocks. , grassy beach, the river water is relatively clear, and the flow is stable; this section consumes very little water and produces a lot of water.

Longyang Gorge to Qingtong Gorge in Ningxia is a canyon section. The river flows through mountains and hills, and due to different lithology , forming a situation of alternating canyons and wide valleys. Among them, there are 19 small canyons, most of which are distributed in ethnic areas, mainly including Longyang Gorge, Jishi Gorge, Liujia Gorge, Bapan Gorge, Qingtong Gorge, etc. Both sides of the canyon are cliffs. The riverbed is narrow, the river channel ratio is large, and the water flow is turbulent. Between Guide and Lanzhou, it is one of the three concentrated sections of the Yellow River tributaries. Important tributaries such as Taohe River and Huangshui River merge into it, which greatly increases the water volume of the Yellow River.

After the Yellow River leaves Qingtong Gorge, it flows northeast along the border of the Ordos Plateau, and then eastward to Hekou Town. The area along the river passes through has a gentle river bed and slow flow. There are large alluvial plains on both sides of the main stream, which is the famous Hetao Plain. Hetao Plain The plain is a famous Yellow River irrigation area with a long history of irrigation. Since ancient times, there have been sayings that "the Yellow River in the world is rich in Ningxia" and "the Yellow River is full of troubles, but only one thing is rich."

The upper reaches of the Yellow River has a large curvature. The control of Nimaqing Mountain, Xiqing Mountain, and Qinghai Nanshan forms an "S"-shaped bend; from Lanzhou to Tongguan, it forms a horseshoe-shaped bend, and the river channel from Lanzhou to Hekou Town is part of this bend. The longitudinal section of the Yellow River bed is composed of five-level "slopes" ——The ladder composed of "flat land", of which there are three levels in the upper reaches: the first level is a slope from the source of the river to Xingxiu Sea, and the flat land is from Xingxiu Sea to Eling Lake; the second level is a slope from Eling Lake to Maqu , Maqu to Guide is flat land; the third level, from Guide to Qingtongxia is slope, Qingtongxia to Tuoketuo is flat land.

The Yellow River Basin is located in arid, semi-arid and semi-humid areas , the total annual average runoff is 57.45 billion cubic meters, equivalent to 1/17 of the Yangtze River. 90% of the Yellow River runoff comes from the upper and middle reaches. The Yellow River flows through the Qinghai-Tibet Plateau above Lanzhou. The land is high and the weather is cold. There is a lot of water supply from melted ice and snow, and the vegetation is The coverage rate is high, the evaporation is small, and the main stream runoff is large. The water volume from Lanzhou to Hekou Town decreases. This is due to the Yellow River diversion for irrigation, strong evaporation, excessive water consumption, and no tributaries to join.

The water source of the Yellow River is mainly supplied by rainwater. Generally speaking, the water volume in winter accounts for about 10% of the total annual runoff, the water volume in spring accounts for about 15--18%, and the water volume in summer and autumn accounts for 70--80%. Summer water volume is often greater than Autumn water, August is the flood month, and heavy rains in summer and autumn often cause flood disasters. However, the autumn water in the Yellow River section of the Hetao area is greater than the summer water, and the maximum water month is September. The amount of heavy rain in the upper reaches is small, and there are many swamps and grasslands in the area. The forest regulates floods, and the rate of flood rise and fall is relatively gentle. The historical maximum peak flow in Lanzhou is 7,500 cubic meters per second, and the maximum flow in Baotou is 4,310 cubic meters per second.

The precipitation in the Yellow River Basin varies greatly between years, resulting in the interannual runoff of the Yellow River. Changes are also large, but the interannual variation in runoff in the upper reaches is smaller than that in the middle and lower reaches.

The sediment content of the Yellow River ranks highest among the world's largest rivers. According to records from Shaanxi County Station, the average sediment content per cubic meter of river water reaches 37 kilograms, and the average sediment load for many years is about 1.6 billion tons. The sediment in the Yellow River mainly comes from the Loess Plateau. The annual sediment load in this area accounts for 90% of the entire main stream. In the upper reaches of the Yellow River, the water flow above Longyang Gorge is very clear, and in the basin below Guide Loess is gradually distributed within. The section of the Yellow River from Qingtong Gorge to Hekou Town has stable water flow and sedimentation. The Ningxia Plain and the Hetao Plain are formed by the alluvial sediment of the Yellow River.

The upper reaches of the Yellow River from Lanzhou to Ice floods occur almost every year in the Linhe Hetao section of Inner Mongolia and in the lower reaches of Shandong. Since the founding of the People's Republic of China, the Party and the Communist Party of China have led the people in the fight against ice ice and have achieved great success, and the hazards of ice and floods have been basically controlled.

The key to controlling the Yellow River is the sediment problem. Doing a good job in water and soil conservation on the Loess Plateau in the middle reaches is the foundation for controlling the Yellow River. The upper and middle reaches of the Yellow River have a large gap and are rich in water resources. Longyang Gorge, Liujia Gorge, and Yanguo Gorge have been built on the main stream. The Longyangxia Hydropower Station is the largest hydropower station on the main stream of the Yellow River, with a design capacity of 1.6 million kilowatts and a dam height of 178 meters, which is currently the highest in the country.

The dam, with a total storage capacity of 24.7 billion cubic meters, is the largest artificial lake in my country. What rivers are there in Binjiang District?
