The Ministry of Water Resources further dispatch the Pearl River Basin Reservoir Group to fully reduce the pressure of downstream flood prevention

Affected by the recent heavy rainfall, on June 18th, the dry flow of dry flow in the middle and lower reaches of the Xijiang River Basin in the Pearl River Basin rose again. On the 19th, the flood No. 4, 2022, and the flood of 2022 in Beijiang. flood.

According to meteorological forecasts, from June 20th to 21st, the Pearl River Basin Liujiang and Guijiang will still have strong rainfall. Regardless of the reservoir regulation, it is expected that 42,000 cubic meters of flood peak flow will occur on the 23rd on the 23rd, and the water level is about 5.5 meters. The flood prevention situation of Xijiang, Beijiang and the Delta region is severe.

After comprehensive research and judgment, from June 16, the Pearl River Water Resources Commission of the Ministry of Water Resources dispatched the backbone reservoir in the basin in advance. First, large reservoirs such as Longtan and Rock Beach on the upper reaches of the Xijiang River stopped flooding. Among them, the outlet flow of the Longtan Reservoir was gradually reduced from 4,000 cubic meters per second to about 500 cubic meters per second. Essence The second is that Liujiang Luojiu, Ma Shi, Langllang and other reservoirs blocked the floods in a timely manner to reduce the flow of 1,000 cubic meters per second per second. The third is the effective peaks of valid peaks such as the Guijiang Qingshitan, Xiaolongjiang, Chuanjiang, Axkou Reservoir and Yujiang Baise. The fourth is to give full play to the role of Xijiang's last flood control control hub Dato Gorge Reservoir. The water level has been reduced to 44 meters, and the 700 million cubic meters of reservoir capacity has been pre -pre -pre -pre -leaked in advance to prevent floods and peaks under the premise of ensuring their own safety.

Before Hong Feng arrived at Wuzhou Station, on the morning of the 19th, Li Guoying, deputy commander of the National Defense General Defense and Minister of Water Resources, rushed to the site of the Dato Gorge Reservoir, and together with Liu Ning, secretary of the party committee of Guangxi Zhuang Autonomous Region, organized the Pearl River Water Conservancy Committee and the Guangxi Water Resources Department to further study and judge Flood prevention situation. Dato Reservoir is planned to schedule 1200 cubic meters per second at 15:00 on the 20th. After taking the above comprehensive measures, the flood flow of Wuzhou Station can be reduced to about 37,000 cubic meters per second, reducing the water level of the Wuzhou river section of more than 1.5 meters, and minimizing the flood control pressure of the lower reaches of the Xijiang River and the Pearl River Delta. On the morning of the 20th, Minister Li Guoying will go to Beijiang to guide the Dili Gorge, Lechang Gorge, Bayou and other reservoirs to dispatch to further reduce the dried flood of Beijiang and reduce the pressure of flood control in the Pearl River Delta. After joint dispatching through the Xijiang and Beijiang dry tributary reservoir group, it can reduce the water level of the Xiliu River section of the Pearl River Delta, and control the waterproof position of the Xijiang, Beijiang and Delta's main embankment in the flood prevention standards.
