After the flood, the nine major rivers and rivers nine times the number of floods in the same period since 1998

"9 major rivers in the country have been numbered, the most during the same period since 1998." Yao Wenguang, director of the Department of Water Disaster Disaster Defense of the Ministry of Water Resources, introduced this year at the State Council of the State Council of the State Council of the State Council of the State Council of the State Council of the State Council of the State Council. Since the flood in the flood.

Yao Wenguang said that since the flood in the flood, my country's floods have occurred, and the flood conditions in the Pearl River Basin are serious. First, the total rainfall is large, and the scope of typhoons has a wide range of influence. The total number of rainfalls in the country is too much. Among them, from late May to mid -June, the rainfall in the Beijiang and Central River in the Pearl River Basin ranked first since the complete information in 1961. Recently, due to the commonly influence of typhoon and cold air, heavy rainfall appeared in the Pearl River, Yangtze River, Huaihe, Haihe, Songliao and other basins. Among them, the rainyst of the Pearl River Basin overlapped in the early stage.

The second is the number of floods, and the distribution is concentrated. A total of nine floods occurred in the country's main rivers and rivers, the most during the same period since 1998. Seven number of floods occurred in the Xijiang and Beijiang of the Pearl River Basin, the most since 1949, and appeared for the first time.

The third is the large level of floods. The Pearl River Basin has two large floods. Among them, the big floods in Beijiang were the largest since 1915.

Fourth, the floods of small and medium rivers are frequent. A total of 487 rivers in the country have more than 80 % of the floods in the water above the police, which is more than the same period since 1998. Fifth, the loss of water conservancy projects.

Yao Wenguang said that the Ministry of Water Resources has done a good job in water and drought disaster defense and daily flood prevention and drought resistance. "It should be said that it has achieved phased goals." First, strengthen monitoring and forecasts and timely issue early warning. In close monitoring of rain, water, flood conditions, rolling forecasting and forecasting, the hydrological department issued a total of 1912 flood warnings. Actively submit information to the Central Office, the State Council, and the State Council. Sending 25.63 million and 1.01 billion pieces to the flood control person and the public of the public. Ten emergency responses have been launched, and 24 working groups and expert groups have been dispatched.

Second, scientific accurately dispatch water engineering. The main person in charge of the Ministry of Water Resources has presided over the businessmen many times, and in the critical period of flood prevention in the Pearl River Basin to the front line of Guangdong and Guangxi, the scheduling and use of the rolling engineering system consisting of river channels, dikes, reservoirs, and flood storage areas. Disaster reduction effect. A total of 2,160 (times) large and medium -sized reservoirs across the country stopped the floods to reduce 910 cities and towns, avoiding personnel transfer of 56 million people (times), and played a role in flood prevention and disaster reduction.

For example, in the process of defending the flood of Beijiang, the measures of "blocking, dividing, storage, stagnation, and discharge" were comprehensive to systematically control the general floods. Including 13 key reservoirs such as Feilai Gorge and Lechang Gorge to accurately reduce the flood peak flow of Shijiao Station 1,100 cubic meters per second. Enable the Daijiang Flood Staldish Area. Timely use downstream reed gates and southwest gates. Through the above measures, the flood flow of Shijiao Station was reduced to less than 18,500 cubic meters per second, which was lower than the design of the Beijiang embankment design to ensure the security of the Beijiang embankment and the Pearl River Delta flood prevention.

During the flood of Xijiang, the joint scheduling was used to use the dry tributary reservoir group. Including, the backbone reservoirs such as Tiansheng Bridge and Longtan are fully blocked. Disposal tributaries, Yujiang Baise, Liujiang Luojiu, Guijiang Qingshitan and other reservoirs to block floods, reduce the pressure of flood prevention in Liuzhou, Guilin and other places, and staggered the peaks of dry flow. The Dato Gorge Reservoir, which was scheduled to be under construction, pre -pre -leaked the Teng Studio in advance to play a key role in precise reduction of flood peaks. "Through the above measures, the flood peak flow of Wuzhou Station is 6,000 cubic meters per second, reducing the water level of Wuzhou about 1.8 meters, and reducing the water level of the Xijiang dry flow water channel of the Pearl River Delta, which ensures the safety of flood control along the Xijiang River and avoid the encounter of the waters of the Xijiang and Beijiang." Yao Wenguang said.

Third, do a good job of typhoon heavy rain and flood defense. Pay close attention to the trend of typhoons such as "Siaba", rolling the business deployment of defense work, and sending a working group to the front line. Schedule the floods such as the Pearl River Basin, the Yixiongsi Basin of the Huaihe River Basin, and the Liaohe River Basin, and dispatch the controlling sluice of Yizun Surabaya to leak the floods of the south and the Luoma Lake, and strengthen the inspection and defense of the embankment of the Beijiang and the Liaohe River to do a good job of heavy rainfall Following security guards in the reservoir, floods and flood disasters of small and medium -sized rivers.

Fourth, it attaches great importance to the safety of the reservoir. Before the flood, the 719 large reservoir dams were announced, and the local and medium -sized reservoirs were urged to implement the "three responsible persons" of flood prevention in small and medium reservoirs. During the flood season, the responsible person of 100 small reservoirs was checked in the flood season, and the early warning information was directly reached to the responsible person of each disease reservoir in the heavy rainfall area. Take effective measures such as reducing water level operation, air library operation, and unblocked flooding channels to prevent the dam and the dam of the dam.
