China release 丨 The Pearl River Basin has once again formed a large basin of the Flood Resources Ministry of Water Resources to dispatch the reservoir group to reduce the pressure of lower reaches

China Net June 20 (Reporter Zhang Yanling) The reporter learned from the Ministry of Water Resources that on the morning of the 20th, Li Guoying, deputy commander of the National Defense General Defense and Minister of Water Resources, came to the Beijiang of the Pearl River Basin to guide Fei Laixia, Lechang Gorge, Bayou, etc. The reservoir scheduling further reduces the dried flood of the Beijiang River, and reduces the pressure of flood control in the Pearl River Delta.

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. 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, and the upstream water was reduced by 3,500 cubic meters per second. The reservoirs such as Liujiang Luojiu, Ma Shi, and Langlang stopped flooding in a timely manner to reduce the flow of the flood peaks of Liuzhou Station by 1,000 cubic meters per second. Guijiang Qingshitan, Xiaolongjiang, Chuanjiang, Axkou Reservoir, and Yujiang Baise effective peaks. In addition, the role of the last flood control control of Xijiang's last flood control hub, which has been given to 44 meters, pre -pre -pre -leaking the 700 million cubic meters of reservoir capacity in advance, and blocking the peaks under the premise of ensuring its own safety.

Before Hong Feng arrived at Wuzhou Station, on the morning of the 19th, Li Guoying came to the site of the Dato Gorge Reservoir and worked with Liu Ning, the party secretary of the Guangxi Zhuang Autonomous Region, to organize the Pearl River Water Conservancy Committee and the Guangxi Water Resources Department to further judge the 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. 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.
