The Yongding River increases the flow of downward flow to open the shrinking river

Yongding River is both the "mother river" of Beijing and an important source of "Sanshan and Five Garden". The reporter learned from the Municipal Water Affairs Bureau that after four years of ecological hydration, the once -dry river channel of the Yongding River has resumed blue waves and long water flow. From the "wet river bottom", "holding hands" with the Yellow River water to using pulse leakage to open the "blocking point" and expanded ecological hydration, etc., the Beijing Municipal Water Affairs Bureau explored a river ecological restoration of "solving ecological problems with ecology" road. It is reported that through cross -basin and multi -water ecological ecology, the 26 -year -old Yongding River and the 22 -year -old Chaobai River realized the entire line of water. , "Five River Enter the Sea" became a reality. The five major rivers, including the Yongding River, Chaobai River, Bei Canal, Luohe, and Ma River, have all reproduced the "flow" in the past 26 years.

The 35 -year -old blocked the river gates ushered in

The maximum leakage flow was flushed the river channel

On June 15, after two and a half months, the Yongding River spring was completed. The Yongding River forms a 270 -kilometer continuous waterway from the official hall reservoir. The Beijing section forms about 1,800 hectares, and the average underwater level in theland on both sides of the river is 1 to 1.5 meters on average. Continue to recover, maintain the flow of not less than 2 months, and effectively construct the regional water power conditions and surface groundwater ecological environment in the southwestern region of the capital.

Recently, the reporter saw at the river Luogou Bridge in Yongding, and saw that the 18 -hole river gate was hovering on the Yongding River. Two of them opened, the clear water flow slowly flowing downstream, forming a small white waves at the exit of the gate. The smoke on the river, the green trees on both sides of the river, the green plants in the center of the river are embellished in it, and from time to time, flying birds fly over.

It is understood that the Luogou Bridge block was completed in 1987. Its role is to ensure that the river channel below the Luxou Bridge of Yongdinghe does not exceed its flooding ability at a certain flood and reduce the pressure of flood control in downstream areas. The gate of the Yongding River is indispensable. On May 10th and May 18th, two pulse tests were opened for the bar gate of the Lalu Gully Bridge of Yongding. By increasing the flow of the lower leakage, the river channels, shaping the river slot, opening the shrinking river channel, restoring the rivers function, and maintaining the health life of the Yongding River Essence

Yongding River 5 times ecological hydration

Realize the entire line of water flowing to the sea for the first time

According to reports, from the perspective of the basin, the Yongding River flows through the three provinces of Inner Mongolia, Shanxi, and Hebei, Beijing, and Tianjin, with a total length of 747 kilometers. Since the end of the 1970s, due to the continuous drought, the water from the upstream decreased, and the water structure along the river was unreasonable. The ecological water volume of the Yongding River was crowded in large quantities. destroy.

In recent years, Beijing has vigorously promoted the comprehensive governance and ecological restoration of Yongding River, and ecological hydration is carried out simultaneously. Wang Junwen, deputy director of the Beijing Water Resources Disposure Management Center, pointed out that the comprehensive governance and repair of Yongding River always follow the work ideas of "solving ecological problems with ecology", open roads with water, and use water to guide the road for five consecutive years. Ecological hydration in Beijing section helps the Yongding River to become a "flowing river, green river, clean river, and safe river." As of now, the municipal water department has carried out five ecological replenishment in the Yongding River, of which the two seasons of spring and autumn have been carried out in 2020.

Wang Junwen said that the vitality of the Yongding River has gone through different stages.

In 2019, the Haihe Water Conservancy Committee of the Ministry of Water Resources organized the cooperation and linkage of the four provinces and cities of Beijing, Tianjin, Hebei and Jin to implement a unified scheduling of the ecological water volume of the basin, and carried out cross -basal ecological hydration on the Yongding River. Through the water replenishment of the year, the Yellow River Wanjiazhai, Bookta, friendship and other reservoirs transferred 270 million cubic meters of water to the government hall reservoir, realizing the historic "hand in hand" of the "mother river" of the motherland and the Beijing "Mother River" Yongding River.

In the previous ecological hydration from 2017 to 2022, every time there are new attempts and explorations. "These attempts and explorations are the specific 'ecological methods' proposed on the status quo' ecology".

In late November 2017 (22-27), the outlet flow of the government hall reservoir was controlled at about 5 cubic meters per second, and the amount of leakage was 1.84 million cubic meters under the cumulative amount. "This is the preliminary attempt of ecological hydration in Yongding River. The official hall Shanxia Water River is only 80 kilometers long. Through water, through this hydration, the minimum flow of the continuous flow of the mountain gorge is initially determined that the continuous flow of the mountain gorge is 5-6 cubic meters per second. At the same time, some problems such as the insufficient flow of river bridge and the drilling bridge over the water bridge during the water passing process are also exposed. "Wang Junwen said.

In 2019, the Haihe Water Conservancy Committee of the Ministry of Water Resources organized the cooperation and linkage of the four provinces and cities of Beijing, Tianjin, Hebei and Jin to implement a unified scheduling of the ecological water volume of the basin, and carried out cross -basal ecological hydration on the Yongding River. Through the water replenishment of the year, the Yellow River Wanjiazhai, Bookta, friendship and other reservoirs transferred 270 million cubic meters of water to the government hall reservoir, realizing the historic "hand in hand" of the "mother river" of the motherland and the Beijing "Mother River" Yongding River. The downstream of the official hall reservoir flows 108 kilometers through the whole line.

In 2020, Luogou Bridge bar gate was leaked by the pulse of the river. The use of artificial sparse excavation induction and diversion to local adjustments to the river grooves, drive the water head to quickly advance, and open up the "blocking point" of the southern section of the plains. It reaches Wuqing District, Tianjin, and is only 23 kilometers from Qujia's hub. A 248 -kilometer continuous waterway formed below the government hall reservoir. "At that time, we followed the water head. The villagers in Lizhou, Hebei Province looked at the water on the right bank. The villagers on the Daxing Fangshan in Beijing were watching the water on the left bank. Many villagers on both sides of the strait were cheering: the water is coming! The water is coming!" Wang Junwen recalled. In 2021, on the basis of the entire water through the Beijing section, the water department accelerated the completion of the small red door regeneration water and the South -to -North Water Diversion midline to replenish the Yongding River. Combined with a variety of water sources such as the official hall reservoir and the small red door regeneration water, a total of 111 million cubic meters were replenished. Using limited ecological water resources to ensure the first time the Yongding River has achieved the first time the water flow of the 865 kilometers of river channels has been traveled into the sea in 26 years.

By April this year, Beijing started the Yongding River spring concentrated water replenishment. On May 12, with the opening of the Zujiadian hub in Tianjin, the Yongdinghe Ecological Make -ups of the Yongdinghe Ecological Make -ups from the Government Hall remembered into the Yongding Xinhe, marking that in 2022 Yongding River realized the entire water through the water. This is also the second time the Yongdinghe River is full of water.

"'Open the road with water', open the river channel with the power of nature; 'use water to lead the road', and reshape the river form of the river with the potential of nature. The rules of river governance and water resource dispatching technology routes of wet river bottom, Lahe tank, Dinghe type, and rehabilitation. "Wang Junwen emphasized.

Ecological continuous improvement

Attract a variety of birds

According to Wang Junwen, the characteristics of the ecological hydration of the Yongding River in the spring of the Yongding River in the "magnitude" is that there is water to replenish, and the amount of water is about 100 million cubic meters. At the same time, the hard -to -use water resources are used to further expand the scope of ecological hydration, add the ecological replenishment of the downstream plain section (Fengtai, Fangshan, Daxing) of the three stores, continue to implement the strategic measures of "hiding water in the ground", and give full play to the optimization and deployment of water resources benefit.

After many replenishment, the Yongding River has glowed with new vitality. The area of ​​water and wetland has continued to increase. It has also become a new habitat for birds. In the past, uncommon birds, such as black, egrets, and Zhendan Yaki began to patronize frequently, settlement here.

According to reports, the next step, the water department will expand sharing, further increase the construction of fishing platforms and water platform facilities, and increase bird observation platforms. In addition, the Yongding River's embankment is planned to be opened this year. Promote construction. After the Zhongdi is open, citizens can walk along the hydrophilic trail to enjoy the scenery of the Yongding River. (Source: Beijing Youth Daily)
