Cover News Reporter Dai Rui.
On February 17, the cover news reporter learned from the Ministry of Water Resources that during the Spring Festival (February 10 to 16), the cumulative average precipitation in the country was 2 mm, of which from the 13th to the 15th, there was a significant precipitation process in the eastern southwest, the northern part of Jiangnan and the southern part of Hubei, with a cumulative surface rainfall of 5 20 mm. On the whole, the water storage situation in reservoirs across the country is relatively good, and the situation of drought and drought is stable.
Li Guoying, Secretary of the Party Group and Minister of the Ministry of Water Resources, presided over a meeting of the Party Group on February 6 to make arrangements and arrangements in advance for further drought prevention and drought control, saltiness and thinning during the Spring Festival; On the 10th (the first day of the first lunar month), the hydrological monitoring of the Yangtze River, the Yellow River and the Pearl River and the risk prevention and control of the salty situation were inspected through the ** connection; On the 15th, 4After level 4**, the immediate deployment requires a comprehensive survey of the seismic damage of water conservancy projects in the earthquake area to ensure the safety of project operation and the safety of drinking water for the people in the earthquake area.
The Ministry of Water Resources organizes and guides relevant river basin management agencies and provincial-level water conservancy departments to make careful arrangements and earnestly implement various defense measures.
The first is to strengthen monitoring and forecasting. Pay close attention to the development trend of drought in the Yellow River, the salty tide in the Yangtze River and Pearl River estuaries, and Yunnan, Guangxi, Guizhou, Sichuan and other places in southwest China; Satellite remote sensing, unmanned aerial vehicle (UAV) aerial photography, first-class surveillance and ground patrol and other "sky and ground" three-dimensional monitoring methods are adopted to track the Yellow River crossing information day by day, daily rolling forecasts and early warnings, and direct the information to the front-line units of anti-bullying. As of 10 a.m. on February 17, the cumulative frozen length of the Yellow River was 705 kilometers (a decrease of 551 km), of which 613 km were closed in the upper reaches (46 km less than the 10th), and 92 km in the middle reaches (9 km less than the 10th).1 km), the Ningxia River section has been opened in its entirety.
The second is to scientifically dispatch backbone reservoirs. Strengthen the scheduling rehearsal, roll the adjustment plan, scientifically dispatch the backbone reservoirs of the Yellow River, such as Liujiaxia, Haibo Bay, Wanjiazhai and Xiaolangdi, and dynamically control the discharge flow of the reservoir, so as to create favorable conditions for the discharge of ice and the smooth opening of the river. Scientifically dispatch the Datengxia Water Conservancy Hub of the Xijiang River (the average daily outflow is controlled by about 2,000 cubic meters per second), implement and complete the third emergency water transfer of the Pearl River in 2023-2024 (from 8 o'clock on February 3 to 8 o'clock on the 10th), and replenish 4 water to the downstream3.2 billion cubic meters, the average flow of Xijiang Wuzhou Station increased by 1,020 cubic meters per second, effectively suppressing the salty tide of the Pearl River estuary, and Zhuhai City seized the "window period" created by emergency water diversion to extract 12.78 million cubic meters of fresh water, effectively ensuring the safety of water supply during the Spring Festival in Macao, Zhuhai and other places.
The third is to strengthen the investigation of risks and hidden dangers. Pay close attention to the risks and hidden dangers of bullying, strengthen the safety management of pontoon bridges across the Yellow River, strengthen the inspection and defense of key projects, key parts, and dangerous sections, and put rescue forces in advance, so as to prepare for prevention and response to ensure anti-bullying and personnel safety. Guide the Guangxi water conservancy department to comprehensively explore the rural water supply projects, reservoir dams, hydrological monitoring and reporting facilities in the earthquake area, etc., and after investigation, there is no abnormal situation in the key reservoirs in the earthquake area, and there is no unsafe drinking water caused by the earthquake.
Fourth, strengthen on-duty duty. Strictly implement the system of being on duty on holidays and leaders leading shifts, pay close attention to the situation of floods, droughts, earthquakes and defense work, and conscientiously do a good job in grasping the situation, reporting information, emergency response and other work.
