On September 13, Wu Daoxi, deputy director of the Water Resources Commission of the Water Conservancy Museum, revealed at the press conference of the water conservancy river basin to resist drought and protect the water supply.

Since 8:00 on September 12, the Ministry of Water Resources launched a new round of special operations for joint dispatching of drought -protection water supply and water supply supply for reservoir groups in the Yangtze River Basin. Wu Daoxi introduced that from September 12th to 13th, the Danxia Reservoir's exit traffic was controlled at an average of 8,000 cubic meters per second at a daily. From the 14th, the outlet flow of the Three Gorges Reservoir was 9,000 cubic meters per second. After that, it will then adjust the flow of the Three Gorges Reservoir in a timely manner according to the need to change the water supply of drought in the middle and lower reaches of the Yangtze River.

"Preliminary analysis, this hydration scheduling can make the water level of Shashi, Chengling, Hankou, and Hukou Station in the middle and lower reaches of the Yangtze River raised 0.9 to 0.1 meters without hydration." Wu Daoxi revealed that at the same time, Hunan, Jiangxi, etc. The province will also do a good job of hydrating scheduling of the two lake water system reservoir groups. The Yangtze River Commission will make precise forecasts on the underwater leakage, and instructs the middle and lower reaches of the Yangtze River to dispatch the culverts, pumping stations and other water conservancy projects such as citations and pumping stations, and strive to play this special operation to the best.

Wu Daoxi said that this year's flood season, middle and downstream of the Yangtze River, and the water in the upstream and downstream of the Yangtze River are dry. The cumulative water replenishment of 3.57 billion cubic meters of midstream and lower reaches effectively guarantees the safety of drought -resistant water supply, summer grain harvest, and electricity in the basin of the basin.

Wu Daoxi pointed out that according to hydrological predictions, from mid -September to the end of November, the precipitation of the Yangtze River Basin will still be less. The bottom line of thinking, prepare for the anti -drought and drought resistance, and strive to solve the two contradictions between the low water volume and the large amount of water to be stored in the water storage period and the amount of water demand for the water period.

In addition, after this round of special hydration operations, the Yangtze River Commission will target the safety of water supply safety, autumn sowing water, shipping safety, and overall ecological safety and energy supplies, and do a good job of joint scheduling in the control reservoir group in the basin. The first is to strengthen the "four pre -pre -pre -" measures, continue to closely monitor the rainyness, water, drought conditions, rolling forecasting and forecasting, and timely release drought early warning information.

The second is the changes in the demand for water use in the dynamic tracking of the basin. In real time, information such as the water from the water from the water, the water demand for autumn, the invasion of the salted tide of the Yangtze River mouth, and the depth of the water depth of the middle and lower reaches of the channel.

The third is to strengthen the scientific scientific scheduling of the reservoir group. According to the development of the drought development and the changes in the water needs of the basin, accurately connect the water supply guarantee goals of different stages, strengthen the discussions and judgments, and carefully calculate the joint scheduling Preserve more water and water storage on the premise.

Fourth, early preparation of reservoir population emergency dispatch plans to deal with extreme dry water.
