On the afternoon of June 10, Beijing ushered in a short-term "wind and rain" strong convective weather; From June 8 to 10, there was heavy rain or rainstorm in Yunnan, Sichuan, Guizhou, Guangxi, Guangdong and Hainan. On June 5, moderate to heavy rain fell in Henan, Guangdong and the eastern and southern parts of Fujian … … Since the flood season, rainstorms in many parts of the country have entered the non-stop "wheel-wheel war" mode.
Since June 1st, most parts of China have entered the main flood season, and the water levels of many rivers have exceeded the same period in 1998. According to the latest report of the National Defense General, although the flood control situation is very severe, the flood control situation in rivers is generally stable and the disaster prevention and mitigation work is under control.
[No longer helpless against the big flood]
Since the flood season, 15 provinces (autonomous regions and municipalities) in the south have ushered in 17 rounds of heavy rainfall, and 124 rivers have exceeded the warning water level. According to the national defense bulletin, the water levels in the main stream of the middle and lower reaches of the Yangtze River, Dongting Lake and Poyang Lake are higher than those in the same period in 1998.
The flood in 1998 has impressed the Chinese people so far: in that year, 20 million hectares of land were flooded, resulting in direct economic losses of more than 250 billion yuan. After a lapse of 18 years, will there be another flood in the basin?
Water conservancy experts said that before 1998, not to mention small and medium-sized rivers, even the dikes of major rivers did not all meet the design standards, and there was still a lack of controlled water conservancy projects. Many places were helpless against major floods. After so many years of management and construction, the river flood control engineering system has taken on a new look.
The data confirms the expert’s statement. Taking the Three Gorges Reservoir, the "backbone fortress" for flood control in the Yangtze River, as an example, the discharge has been gradually increased since April 22, and the real-time water regime at 8: 00 on May 31 shows that the water level in front of the dam has dropped to 148.62 meters.
This year, the flood waves brought by 17 rounds of heavy rainfall quickly disappeared in rivers and lakes, which is undoubtedly attributed to the long-term construction of water conservancy infrastructure in China.
[Warning flash floods, knowing where to run]
From May 19 to 20, the rainfall in Licun Town, Rong County, Yulin City, Guangxi was as high as 252.2 mm in 20 hours, and flash floods may come at any time.
At 10: 00 am on the 20th, Huang Xianli, a village branch secretary in Rong Feng, received a flash flood warning message from the county on his mobile phone, and immediately sounded the alarm.
When he went out to mobilize, he found that many villagers had gathered in the resettlement highland according to the flood control plan. "The flood is coming, we know to run, and we know where to run!" Sister Huang, a villager who moved quickly in this rainstorm, said.
Thanks to the early warning system of mountain torrents, all the people in Rong Feng Village ran ahead of the mountain torrents in this "speed of life and death" competition.
Zhang Jiatuan, spokesman of the National Defense Office, said that since the beginning of this year, 675 counties (cities, districts) in 10 provinces (autonomous regions and municipalities) have issued 6287 county-level flash flood disaster warnings, and about 490,000 people threatened by flash flood disasters have been transferred.
According to the data provided by the Ministry of Water Resources, up to now, the national flash flood disaster prevention project has invested a total of 27.9 billion yuan, making it the largest non-engineering project in the history of water conservancy construction in China.
[Natural disasters are unpredictable, and responsibilities can be refined]
Jiangxi Province announced the list of persons responsible for flood control and drought relief at all levels, extending the persons responsible for flood control to 1,598 townships; Hubei implements the responsibility system for flood control and drought relief … …
"Natural disasters are difficult to predict, but the responsibility can be completely refined." When deploying flood control work, the relevant person in charge of Hunan Province said.
As early as this year’s two sessions, Chen Lei, Minister of Water Resources, made it clear in an interview: "The responsibility system for flood control and drought relief chief executives will be fully implemented, and the list of flood control and drought relief chief executives such as rivers and large and medium-sized reservoirs across the country will be announced to the public."
The "Guangdong Three-prevention Responsible Person Information Management System" has been built and put into use in Guangdong Provincial Three-prevention Headquarters, which contains the information of 536,256 registered three-prevention responsible persons in the province. "The superior three defense departments often check our on-duty situation through video connection. Sometimes when we go to the toilet or take a shower, we have to find someone to take over temporarily." A staff member of Dongfeng Reservoir said.
From the central level to the grass-roots level, the responsibilities are clear step by step, and the pressure is transmitted layer by layer, which highlights the characteristics and advantages of the flood control system in China. Our reporter Pan Xutao
