Xiaolangdi Water Conservancy Project is the largest water conservancy project in the Yellow River Basin, located 40 kilometers north of Luoyang City, Henan Province, the development goal is to flood control, anti-flooding, siltation reduction, taking into account water supply, irrigation and power generation The total storage capacity of 100 million cubic meters, the installed capacity of the hydropower station is 1.8 million kilowatts, and the water supply is increased by 4 billion cubic meters The project has been completed in 2001

Sanmenxia Water Conservancy Hub (at the junction of Pinglu, Shanxi and Sanmenxia City, Henan, put into use in 1960. It is located in the lower part of the middle reaches of the Yellow River, connecting Henan and Shanxi provinces, and the control basin area accounts for 89% of the total basin area of the Yellow River, with 89% of the incoming water and 98% of the incoming sediment. The project started in April 1957 and was completed and put into use in April 1961.

Article**1 Sanshenggong Water Conservancy Hub: (Dengkou, Inner Mongolia, put into use in 1966.) The Sanshenggong Yellow River Water Conservancy Project was built in 1959 and is located at the entrance of the main trunk canal in Pengkou County, Bayannur City.

The Yellow River flows 345 kilometers through Bayannur City, irrigating the fertile Hetao Plain, mainly by the main trunk canal of more than 180 kilometers long from east to west. The Sansheng Gong Water Conservancy Project is just like the heart of the main trunk canal, which is a sluice and dam project that focuses on irrigation, and has navigation, road transportation, power generation, industrial water supply, and comprehensive utilization of fishery and aquaculture. The barrage is more than 309 meters long, standing majestically on the rolling Yellow River, with a grand scale and majestic momentum.

It has become a unique cultural landscape of the 800-mile Hetao.

There is a Sanmenxia dam in the Yellow River basin, and there is also a Xiaolangdi water conservancy project.

There are a lot of these, among which the more famous one is the Xiaolangdi Water Conservancy Project, which has made great contributions to China's people's livelihood.

The largest water conservancy hub of the Yellow River is the Xiaolangdi Water Conservancy Project.

The Xiaolangdi Water Conservancy Project is a key project for the control and development of the Yellow River, which is a key project of the national "Eighth Five-Year Plan", which was intercepted in 1997 and completed at the end of 2001. Xiaolangdi is located on the main stream of the Yellow River, which is 40 kilometers north of Luoyang, Henan Province, 130 kilometers away from Sanmenxia Reservoir and 115 kilometers away from Zhengzhou Huayuankou, which is the only control project that can obtain a larger storage capacity below Sanmenxia, the main stream of the Yellow River.

The Xiaolangdi Water Conservancy Project is a key project for the control and development of the Yellow River, which is a key project of the national "Eighth Five-Year Plan", which was intercepted in 1997 and completed at the end of 2001. Xiaolangdi is located on the main stream of the Yellow River 40 kilometers north of Luoyang, Henan Province, 130 kilometers away from Sanmenxia Water Fangbiku on the top, and 115 kilometers away from the Huayuankou of Zhengzhou on the bottom.

In 2003, when the Yellow River experienced an autumn flood that was rare in history, the Yellow River Defense General opened the Xiaolangdi Reservoir to store more than 10 floods, avoiding a large-scale floodplain disaster in the lower reaches of the Yellow River, and at the same time, turning nearly 10 billion cubic meters of flood water into water resources and storing them in the reservoir.

Since the Xiaolangdi Water Conservancy Project was put into operation, the Yellow River has continued to flow for 13 consecutive years, and has successively completed 7 cross-basin emergency water diversion tasks such as the diversion of the Yellow River to Tianjin, the diversion of the Yellow River to Qingdao 12 times, and the diversion of the Yellow River to Jidian Lake 5 times. It has also achieved 13 consecutive years of safe flooding in the lower reaches of the Yellow River, and basically lifted the threat of flooding in the lower reaches of the Yellow River. It has effectively improved the ecological environment of Xiaolangdi reservoir area and downstream areas.

Watershed profile.

1.The Yellow River Basin stretches from Bayan Kala Mountain in the west, the Bohai Sea in the east, the Qinling Mountains in the south, and the Yinshan Mountain in the north, with a basin area of 10,000 km.

2.The Yellow River originates at the northern foot of Bayan Kala Mountain on the Qinghai-Tibet Plateau, flows through 9 provinces and autonomous regions including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan and Shandong, and flows into the Bohai Sea in Kenli County, Shandong, with a total length of about 5,400 km.

3.From the source of the river to Tuoketuo in Inner Mongolia, most of the areas above Lanzhou are well covered with plants; The main stream from Maduo to Qingtongxia has many canyons and is rich in water and energy resources; Below the Qingtong Gorge is the Hetao Plain, which has developed irrigation and is navigable. Tuoketuo to Taohuayu in Henan Province is the middle reach, and there are also abundant water energy resources; The two banks are the Loess Plateau, with little vegetation and serious soil erosion, which is the main sediment of the Yellow River.

Taohuayu to the mouth of the river is the downstream, most of the embankments on both sides of the bank have been built, and the sediment accumulation makes the riverbed generally 3 5m higher than the ground on both banks, and the more reaches 10m, so it is called the hanging river; There are many irrigation areas along the coast, and the main stream is also navigable. Near the estuary, the Yellow River estuary channel is constantly silted, extended and diverted, and has a strong land-building effect. There are 10 tributaries with an area of more than 10,000 km that directly flow into the main stream in each river section, with the Wei River having the largest area and water volume.

As Chinese, we all know that the Yellow River is a mother river. However, many people's understanding of the Yellow River is limited to the content of geography textbooks, such as where it originates, which provinces it flows through, and which sea it eventually enters. In fact, the places where the Yellow River flows through not only have snow-capped mountains, grasslands, canyons, deserts, plains, cities and other topography, but also have different ethnic customs and local customs.

Shangshu-Yu Gong" said that the river is a stone, as for the dragon gate. This Jishi Mountain is located at the junction of the two provinces of Qinggan in the upper reaches, and Longmen is located in the territory of Henan Province in the lower reaches. Take Jishi Mountain as an example, the Yellow River flows out from the source of Ngoling Lake and Zhaling Lake, passes through the Jiuqu ileum of the grassland in northern Sichuan of Gannan, flows out of the Qinghai-Tibet Plateau from Longyang Gorge and Lijiaxia Reservoir, flows under Jishi Mountain, and enters the Loess Plateau from Jishi Gorge.

There is a county town not far from Jishi Gorge, which is Jishishan County, Linxia Prefecture, Gansu Province, and this county has a unique ethnic security clan in Gansu.

The five major irrigation areas through which the Yellow River flows are:

Huangshui Valley. Hexi Corridor.

Hetao Plain. Ningxia Plain.

North China Plain.

The upper reaches of the Yellow River: the mountains are high and steep, the drop is large, and there is a lack of abundant hydraulic resources. After the Yellow River flows out of the Qingtong Gorge, its terrain is flat and open, and it enters 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.

Midstream: In summer and autumn, there are many heavy rains, abundant sand sources, more water and more sand, large flood peak flow, high sediment content, becoming a world-famous sandy river, river siltation and erosion of river sections interchange, canyons and wide valleys alternate.

Downstream: It flows through the North China Plain from west to east, and the slope of the Shihong River channel 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, the two banks are almost all by the embankment as a barrier, the river beach is generally about 2-5 meters higher than the ground on both banks, and some are as high as 10 meters, which is the world's famous "hanging river".

The middle and upper reaches of the Yellow River are mainly mountainous, and the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is also known as the river with the most sediment content in the world. But in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization.

The Yellow River is the main birthplace of Chinese civilization, and the Chinese call it the "Mother River". Every year, 1.6 billion tons of sediment are produced, of which 1.2 billion tons flow into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain that is conducive to cultivation.
