[The Yellow River Anlan] The small wave bottom of the Yellow River: The precise regulation of the upper and lower precise regulation allows the Yellow River to become the benefit of the people's happiness.

China Net Luoyang, September 16th (Reporter Li Peang) More than 20 years ago, a dam at the small waves at the last section of the canyon exit in the middle of the Yellow River stopped the Yellow River and sand with a large amount of sand. Over the years, water conservancy workers have been exploring the road of governance of the Yellow River and sediment here, innovatively put forward the idea of ​​"one high and one low", and use the Yellow River dry tributary reservoir group to implement joint dispatch, water and sand and regulation, re -coordinate the Yellow River water water Sand relationship.

Jiuqu Yellow River is thousands of miles, how much sediment does the Yellow River have?

The Yellow River originated from the Payra Mountain in the Qinghai -Tibet Plateau. It winds down through the Loess Plateau, wrapped in a huge amount of sediment. According to statistics, the Yellow River takes 1.6 billion tons of yellow sand from the Yellow River every year, of which 400 million tons of sediment do not flow into the sea. Instead, it is deposited in the downstream river. Over time, the world -famous hanging river is formed.

Li Peng, Director of the Water Quantitative Division of the Water Conservancy Hub Management Center of Xiaolang Downs, was interviewed by Li Peigang, a reporter from China Network

Li Peng, director of the Water Resources Dispatching Division of the Water Conservancy Hub Management Center of Xiaolang Downs, introduced that the Xiaolang bottom water conservancy hub is a large -scale comprehensive use of the Yellow River governance development milestone project since the founding of New China. It also controls nearly 100 % of the sediment. Therefore, adjusting water and sand relationships has become the "highlight" of the small wave base project.

Faced with the steady stream of storage and sediment, the small wave bottom water conservancy hub adopts advanced engineering design schemes and optimized reservoir use methods, so that a considerable part of the sandwood library capacity is repeatedly used. At the same time, using the reservoir's adjustment reservoir, artificial rushing river channels and reducing downstream river stasis.

The water and sand and water and sand are not coordinated. From July 4th to July 15th, 2002, the Yellow River conducted the first water adjustment test. This time it was called the greatest river sediment governance test of human beings, realizing the dream of several generations of the Yellow River people. The milestone of Huang to the transformation of yellow to modern times has changed dramatically.

It is understood that the Yellow River dry tributary reservoir group implements a joint dispatch, using the flood to stop the peak of the upper reaches of the Yellow River, and under the premise of ensuring flood prevention safety, try its best to stop the floods, maintain the high water level of the reservoir, and play the role of the "leader" reservoir across time. The middle reaches of the small wave bottom reservoir will be opened up to reduce the operation of the water level, leaving enough flood prevention library to ensure the safety of flood control, reduce the probability of flood beach, take into account the storage of the reservoir river, and shape the stable Zhongshui river tank.

On October 9, 2021, due to the continuous rainfall and water coming water, the small wave bottom reservoir reached a historical highest water level of 273.5 meters. "In this autumn flood test, there is a large work highlight of flood control is that the water volume control accuracy is high." Li Peng said, "If the water control is excessive, the downstream will be disconnected; too little will cause floods." The small wave bottom reservoir is fully invested in the application of flood control. By predicting the amount of floods and water, combined with the flow of downstream river channels, the amount of water control is adjusted in real time.

The small wave bottom of the Yellow River: The precise regulation and control of the Yellow River has made the Yellow River a small waves at the last section of the canyon exit of the Yellow River more than 20 years ago. A dam from the Yellow River and sand with a large amount of sand with a large amount of sand. Over the years, water conservancy workers have been exploring the road of governance of the Yellow River and sediment here, innovatively put forward the idea of ​​"one high and one low", and use the Yellow River dry tributary reservoir group to implement joint dispatch, water and sand and regulation, re -coordinate the Yellow River water water Sand relationship. This year, Qinghai has accumulated a total of 21.85 million fishes for various fish. The reporter learned from the Qinghai Provincial Department of Agricultural and Rural Affairs that since this year's "Fish Fish Day", Qinghai Province has accumulated a total of proliferation flowing flowers in the Yangtze River and the Yellow River Basin. , 750,000 abdomen fish, Qiqiao 腹 腹 、 、 、 、 、 、 、 、 、 21.1 million nude carp naked carp in Qinghai Lake, with a total of 21.85 million, successfully completed the fish proliferation and release tasks in 2022. Focusing on the new era of riverside governance concept "River International Forum" in Beijing, in order to implement the national "rivers' strategy" and landscapes, forests, lakes and sand system governance concepts, and promote the high -quality development of water conservancy. On the day, it was held in Beijing with a combination of online and offline. The well -known academicians and senior experts and scholars at home and abroad conducted academic exchanges around the conceptual changes of rivers and rivers governance and the application of new technology applications, and released the first issue of "River" (River).
