China News Service, April 1st According to the website of the Ministry of Water Resources, according to the forecast of the Yangtze River Water Conservancy Commission, the precipitation in the Yangtze River Basin during the flood season this year is generally normal, but the distribution of precipitation is uneven in time and space, and waterlogging is more severe than drought. Focus on preventing severe floods and flash floods due to concentrated rainfall, and at the same time, be alert to the possibility of a sudden turn of floods and droughts.
On March 31, the Yangtze River Water Resources Commission convened a comprehensive conference to implement the Ministry of Water Resources' drought and drought disaster prevention work deployment, analyze and judge the situation of the water and rain in the Yangtze River Basin during the flood season this year, and study and deploy the recent flood and drought disaster prevention related work.
At the meeting, the Hydrographic Bureau of the Yangtze River Water Resources Commission reported the current water and rain situation in the Yangtze River Basin and the forecast of flood and drought trends in the 2020 flood season, and the Defense Bureau reported the progress of the recent flood and drought disaster prevention work.
According to hydrometeorological analysis, from January to March this year, the accumulated precipitation in the Yangtze River Basin was too high, especially since March. The rainfall process in the Yangtze River Basin has been frequent, and the water levels of the stations in the middle and lower reaches of the Yangtze River have fluctuated. The average water level in February and March was generally high.
According to forecasts, precipitation in the Yangtze River Basin is generally high during the flood season this year, but the distribution of precipitation is uneven in time and space, and waterlogging is more severe than drought. Precipitation during the main flood season is too high, and we should focus on preventing severe floods and flash floods due to concentrated rainfall. Rapid flooding and drought phenomenon.
The director of the Yangtze River Water Conservancy Commission, Ma Jianhua, emphasized that from the perspective of hydrometeorological forecast, this year's flood season is likely to have regional floods and even large river basin floods. All relevant departments and units must firmly implement the Party Central Committee and the State Council. Decision-making deployment and various work requirements of the Ministry of Water Resources, fulfilling their responsibilities, uniting and cooperating, while doing a good job in epidemic prevention and control, do a good job in all preparations for flood and drought disaster prevention, strengthen monitoring and forecasting, and discuss and judge , Scientific scheduling, technical support, do not fight unprepared battles.
Regarding the recent flood and drought disaster prevention work, Ma Jianhua requested that the first is to strengthen the rolling forecast of flood and drought trends in the river basin during the flood season this year, and the joint research and consultation of the Ministry of Encryption and Water Resources Information Center and the Yangtze River Basin Meteorological Center will discuss and judge;
The second is to pay attention to the recent heavy rainfall process in the two lakes, release timely flood reports, and urge related areas to take precautions against the heavy rainfall process;
Third, pay close attention to the decline of the Three Gorges and other key reservoirs. The Danjiangkou Reservoir ’s pre-flood subsidence plan is further detailed. The principle of water level diversion scheduling management is based on Danjiangkou Reservoir ’s water level control at the end of the month, and it is controlled at the tenth of each month for refined scheduling.
Fourth, the Defense Bureau, the Yangtze River Fisheries Research Institute, and the Institute of Water Engineering Ecology strengthened the coordination and research, and timely carried out the ecological dispatching test of the breeding demand for viscous spawning eggs;
Fifth, make every effort to promote pre-flood preparations, do a good job in reviewing and approving relevant dispatching plans, and complete the revision of the Three Gorges Reservoir dispatching rules in a timely manner, and further implement the pre-flood inspections in the Yangtze River Basin.
