The groundwater level in Beijing's Shunyi District continues to rise, and a number of new rivers with water have been added

36.99 meters, 34.52 meters, 32.87 meters, 28.07 meters, this is a series of exciting figures, since 2018, the groundwater level in Shunyi District has continued to rise, coupled with ecological water replenishment and other factors, Shunyi District has added 125 kilometers of new waterfill rivers (canals) and 87.7 kilometers of water rivers (canals).

There are 87.7 km of new water river (canal) road

Since the beginning of this year, due to factors such as rainfall, ecological water replenishment and strengthening groundwater supervision, the groundwater level in the whole region has continued to rise. According to the 10th issue of the Shunyi District Groundwater Bulletin this year, as of October 26, the average burial depth of groundwater in the whole region was 28.07 meters, an increase of 4.82 meters over the same period last year and an increase of 3.89 meters over January this year.

The staff of the Water Utilization Management Section of the Shunyi District Water Affairs Bureau introduced to reporters the reasons for the recovery of the groundwater level, and in the first half of this year, the Chaobai River experimental water replenishment was implemented and the Chaobai River ecological water replenishment implemented after the flood this year to before the flood next year, so that the Shunyi section of the Chaobai River was fully connected to the water for the first time in 22 years, and the groundwater level rose by 3.2 meters compared with before the replenishment, effectively promoting the conservation of underground water sources and improving the self-purification capacity of the river. Since September 10, ecological water replenishment has been carried out along the Chaobai River, XiaozhongHe River and Tangzhishan Reservoir in three ways, forming a number of water replenishment channels such as Hanshiqiao Wetland, Zhonggan Canal and Fangshi Canal, adding 125 kilometers of water replenishment river (canal) road and 87.7 kilometers of water river (canal) road. Moreover, this year's ultra-long flood season rainfall was 59, and the average precipitation in the whole region was 863.2 mm, which was 90% and 1.8 times more than the same period of the year and the same period last year. Under the premise of ensuring flood control safety, the District Water Bureau has accurately dispatched to maximize the conversion of rainfall into effective water resources, effectively conserve and promote the recovery of groundwater. In addition, the District Water Bureau strengthens groundwater supervision. Do a good job in the water impact assessment of construction projects, and have passed 65 cumulative reviews since the beginning of this year; optimize and improve the groundwater sinking and water withdrawal approval process, and complete 758 cases of approval this year; strictly control groundwater exploitation, so that one eye can be updated, sealed and filled, and 60 wells have been sealed this year; and the use of groundwater has been standardized according to law.

The 78 main canal belongs to the Baihe Irrigation District, built in 1958, with a total length of 2.7 kilometers, and is connected to the Jingmi Diversion Canal, and since 1991, the main canal has no longer played an irrigation role. Recently, the Shishan Gate of the 78th Main Trunk Canal of the Baihe River in Jingmi Drinking Water Canal opened the gate to carry out ecological water replenishment to the towns of Beishi Trough, Zhao Quanying, and Gaoliying, and the total length of the water replenishment was 22 kilometers. After 30 years, the main canal was once again opened to water.

The Tangzhishan Reservoir, which has dried up for 23 years, has reappeared in waves

Tangzhishan Reservoir is located in the north of Tangzhishan Village, Mulin Town, and this year, the Tangzhishan Reservoir, which has been sleeping for 23 years, has "woken up" and reproduced the waves.

Recently, the reporter came to the Tangzhishan Reservoir to see that the reservoir that has been dry for 23 years has come back to life, the water surface is sparkling, dozens of wild ducks are playing on the river, the villagers are walking and jogging at the edge of the reservoir, and the dancing shallow mountains at the end of the reservoir are rolling and rolling, and a beautiful picture of harmonious coexistence between man and nature is unfolding in front of him. It is reported that the Tangzhishan Reservoir was completed in 1958, and after years of drought, the water level gradually declined, and since 1998 it has been in a state of empty operation, and the original turquoise water surface has become an overgrown beach. At that time, many people lamented that the abundant water feature of the Tangzhishan Reservoir was absolutely loud. However, to everyone's surprise, this year, thanks to the ecological water replenishment project and the abundant summer rainfall, the beautiful scenery of the Tangzhishan Reservoir has reappeared in front of us. "The memory of the water in the reservoir is still stuck in my childhood, and I didn't expect that more than twenty years later, I could still see this beautiful scenery next to the mountain. These days, not only the nearby villagers, but also many people from afar also come to enjoy the beauty of the reservoir. Ms. Wang, a villager in Jiashan Village, Mulin Town, said as she took out her mobile phone to take a picture of the beautiful scenery in front of her.

Sun Mingzhan, director of the Tangzhishan Reservoir Management Office of the Shunyi District Water Affairs Bureau, told reporters: "The 'awakening' of the Tangzhishan Reservoir has a deeper significance, and the biggest benefit is that the water source is replenished underground, conserving and repairing the underground emergency water source. "It turned out that the bottom of the TangZhishan Reservoir and the surrounding rivers was the source of Beijing's Mihuaishun underground water. This is the first emergency water source built in Beijing to alleviate the pressure on water supply, and since its completion in 2003, it has been continuously mined for many years to provide drinking water for Beijing citizens. At the beginning of mining, the underground burial depth of Huairou's backup water source was 16.8 meters, and the exploration data in October this year showed that the underground burial depth was 12.98 meters, which was a sharp recovery from the beginning of mining, and the groundwater resources were more abundant. "Our water affairs department has taken measures such as hydrological water quality testing, dispatch and drainage to ensure the smooth development of ecological water replenishment, provide a good ecological and beautiful water environment for the public, and ensure that more water resources are stored in the ground." Sun Mingzhan said.

The Shunyi section of the Chaobai River is fully connected to the water

Chaobai River can be said to be the mother river of Shunyi, this year, the Shunyi section of chaobai river has achieved the first full line of water in 22 years, which has surprised Shunyi people.

On April 30 this year, the Chaobai River was launched with a one-month period of intensive water replenishment. After the ecological replenishment, the Shunyi section of the Chaobai River has achieved full water access. Today's Chaobai River, water birds fly low along the water surface, wild ducks play in the river, picturesque. However, in the memory of many young people, the Shunyi section of the Chaobai River is only a 21-kilometer continuous water surface formed from below the Chaobai River earth dam and the north of the city, they have not seen the Chaobai River, which is 38 kilometers of water today, and now the chaobai River is full of them. "I often pass by niushan bridge, but the impression is that it has always been dry, yellow sand, dry grass, and no life. In May this year, I was pleasantly surprised to find that there was water under the Niushan Bridge, and in the past six months, the water surface has become wider and wider. Every time I walk from here, I have to look at this water feature. Citizen Mr. Zhao said.

Standing on the bank of the Chaoyang River Sun Gate, the water surface is wide and calm, the sun shines on the water, soft with a hint of warmth, although the trees on both sides have withered yellow, but it is more beautiful in winter. "Winter is a tranquil beauty, summer is a more vibrant beauty, many people love to come here to walk, take pictures, run, look at such a beautiful scenery, the mood is also better." 」 Mr. Wang, a citizen, walked on the shore and sighed at the beauty that this water feature brought to life.

The ecological environment of the Shunyi section of the Chaobai River has been further improved, and the scenery has become more and more beautiful, attracting a variety of water birds such as black swans, white swans, and white bone-top chickens to stop and multiply here. (Zhang Lu)
