At 17:00 on September 21, the water level in Lingji, Dongting Lake, fell to 19.84 meters, fell below the 20 -meter mark.

Continuous drought leads to the "water nest" of Dongting Lake thirst, and the Hunan section of the Chizhi and Hunan Hunan has continued to disconnect for more than 60 days.

Moisturizing and drought, and the segmental hydration project (referred to as "hydration project") in Dongting Hubei played an important role. On September 21, the reporter saw a hydration point in Junshan District, Huarong County, Huarong County and Changde City, Changde City, and Datong Lake District, Yiyang City. The water, Zhengyuan continues to flow into the farmland and water factories through the canal, "quench thirst" for Dongting Lake District.

Moisturizing projects have accumulated over 600 million cubic meters of hydration

On September 21, the reporter saw in the flood port of Junshan District, Yueyang City that a water pumping boat with a length of 66 meters long and 14 meters wide was lying on the Yangtze River like a giant whale. 7 large pumps with a power of 400 kilowatts are placed in a depth of 1 meter at the bottom of the ship; 7 pipelines are inserted into the Yangtze River with one end and connected to the water canal. Huahong Canal and Huarong River hydrated to Junshan District and Huarong County.

In Dongting Hubei, rivers, lakes and ditches are intertwined, and they are known as "water nests". In recent years, due to changes in the relationship between Jiang and Lakes, the diversion of the four ports of the Yangtze River has decreased significantly, and the "water nest" has appeared from time to time.

Quite thirst for "water nest". In 2017, our province studied proposed the overall plan of a section and hydration in Dongting Hubei. The hydration project was divided into two phases. network. At the end of 2019, the first phase of the segmentation of the section of the Hubei area of ​​Dongting was completed, and the total diversion flow was 192 cubic meters per second. In the second half of 2021, the construction of the second phase of the project will be completed in 2023.

This year, the drought of drought in our province has continued to spread, and the hydration project has fully exerted the benefits of water replenishment. It has accumulated a total of over 600 million cubic meters and a maximum daily water replenishment of 16.62 million cubic meters. Essence

Conservation and irrigation, "water nest" quench thirst

"From August 2nd, hydration has been replenished, and more than 74 million cubic meters of hydration have been hydrated." Said Cao Weidong, director of Yueyang City Water Disaster Disaster Defense Center.

On September 21, the reporter saw in the Water Factory of Junshan District that the water plant took the Yangtze River water as the source of the water, and bears the drinking water of 29,000 people. This year, due to drought, the water supply capacity was insufficient. The water plant was pumped from the Huahong Canal pump, and the water replenishment project was transmitted to the water plant, which increased the water supply of 2,000 tons per day.

Continuously sunny and hot, which led to the "thirst" in Junshan District and Huarong County. On September 21, the reporter saw in Shishuling Village, Xucheng Town, Junshan District that Wu Xinhua, a large grain planner in the village, was busy in the field. Wu Xinhua planted 800 acres of water fields this year, and the yield per mu can exceed 500 kilograms.

"Fortunately, the water replenishment project was delivered in time, otherwise it would be huge this year." Wu Xinhua said that in mid -August, when the medium rice grouting was water, it continued to drought and made him anxious.

From August 10th, the hydration project drained the water from the Yangtze River to the Huahong Canal, and flowed into Wu Xinhua's field through the canal, which solved his urgent urgent need.

At present, the hydration project has replenished more than 3 million cubic meters of hydration in Junshan District and Huarong County, ensuring the irrigation water demand for more than 900,000 mu of cultivated land in the two places.

The Eastern Hydrating North Line Project located in Anxiang County was opened in 2021. The controlling project has been completed, but the downstream channels have not yet completed dredging and slope protection.

Droughts are not waiting for people. The reporter saw at the scene that the local dyke pumping station was urgently enabled, and the flow of 10 cubic meters per second was raised from Songzi River to the Guanxian Town and other places in Anxiang County. Replenishing 10 million cubic meters of water reducing the influence of drought.

Make up a lake "living water"

In the golden autumn season, the Datong Lake in Yiyang City is clear and blue, crab fertilizer and Jingmei. In addition to the drought resistance, the hydration project also played an important role in the ecological environmental protection of the lake area.

After the completion of the hydration project, the concept of ecological governance of the river and lake is introduced to combine the pump station to adjust the water with the inner and outer water network. Liaison, water replacement accelerated, and the water quality has been significantly improved. Once the lake "dead water" became a lake "living water".

With "living water", it is necessary to control the water. The water supply range of hydration projects reaches tens of kilometers and spans multiple counties (cities, districts).

"Arrange a special person to monitor the flow of the diversion of hydration projects every day to ensure that the amount of water volume is fairly distributed." He Hui, director of Yueyang Water Resources Bureau, said that the next step will be constructed to build online monitoring and measurement facilities, remotely control the gates of the Huahong Canal, and implement it in an all -round way. Informatization management, reduce and avoid water contradictions, and distribute water resources more reasonably.
