Since June 30th, the strongest rainfall has occurred in the middle and lower reaches of the Yangtze River, along the Yangtze River, in the Jianghuai area and in the southwest and east, and some areas have suffered from severe floods.
Its characteristics: first, the rain area covers a wide range.
The rainfall area covers Yunnan, Guizhou, Sichuan, Chongqing, Hunan, Hubei, Shaanxi, Henan, Anhui, Jiangsu, Shandong, Shanghai, Zhejiang, Guangdong and Guangxi 15 provinces (autonomous regions and municipalities). The rain areas larger than 100 mm and 50 mm reach 290,000 square kilometers respectively.
Second, the accumulated rainfall in the process is large.
More than 200 mm in central and southern Anhui, eastern Hubei and southern Jiangsu; The maximum accumulated rainfall is 480mm in Qian Fan, Lu 'an, Anhui, 460mm in Zhangjiafan, Huanggang, Hubei, and the maximum daily rainfall is 325mm in Qiting, Huanggang, Hubei. The 24-hour rainfall of Sizhou River in Jinzhai, Anhui Province exceeded the historical extreme.
Third, floods in small and medium-sized rivers have risen sharply.
Affected by heavy rainfall, 9/kloc-0 rivers in Hubei, Anhui, Henan, Jiangsu, Zhejiang and other provinces have exceeded the warning level flood, 28 rivers have exceeded the guaranteed level flood, and 5 rivers in Anhui, Xihe River, Yongan River, Fengle River, Erlang River and Hubei Jushui have exceeded the historical maximum level flood.
Affected by the superposition of previous high water levels, the water levels of the Yangtze River, Huaihe River and Taihu Lake rose rapidly. 1 In July, the Yangtze River was flooded this year, and the peak flow of the Three Gorges Reservoir exceeded 50,000 cubic meters per second. At 3 o'clock on the 3rd, the water level of Datong Station in the lower reaches of the Yangtze River exceeded the police, and the No.2 flood of the Yangtze River was formed.
At 8 o'clock on July 3, the water level of Taihu Lake rose to 4.6 1 m, which was 0.8 1 m higher than the warning water level. Wuxi, Jiangsu, Qian Fang and other stations 1 1 exceeded the same period in history, and the highest water level of Suzhou Station of the Grand Canal exceeded 0.60m on the 2nd 10, ranking first since 1977.
Fourth, the floods in some areas are serious.
The heavy rainfall affected 6.87 million people in 7 provinces (cities) 163 counties in Zhejiang, Anhui, Hubei, Hunan, Chongqing and Guizhou. 0/4 people died/kloc, 8 people were missing, 9,000 houses collapsed, the affected area of crops was 7 10/0,000 hectares, and the direct economic loss was about 9 1 100 million yuan.
There are many executions in Huangpi and Xinzhou, Wuhan, Hubei Province, and 374 dangerous places in dikes, dangerous reservoirs and general dikes of small and medium-sized rivers in Anhui Province.
In view of the heavy rainfall process, the National Defense General Administration, the River Basin Defense General Administration and the relevant areas made every effort to prevent and respond to heavy rainfall in accordance with the deployment and requirements of the CPC Central Committee and the State Council.
The first is the deployment and supervision of encryption consulting.
The National Defense General Encryption Conference made a judgment, issued seven urgent notices, made defense arrangements in advance, classified guidance and focused deployment of heavy rainfall prevention work, and conducted spot checks on flood control duty in 14 provinces (autonomous regions and municipalities), provincial, city and county defense offices and 3 river basin institutions, with a total of 67 units.
Second, relying on the former command to strengthen guidance.
The main responsible comrades of the party and government at all levels in the disaster area went deep into the front line of disaster relief and commanded from the front.
The National Defense General dispatched four working groups in advance to assist the flood control and flood fighting in the basins of Hunan, Jiangsu, Zhejiang and Shuiyangjiang before heavy rainfall. According to the changes of rain and water conditions, eight working groups and expert groups were dispatched to Jiangsu, Anhui, Shandong, Hubei, Sichuan and Chongqing in time.
Hubei Province sent 22 working groups and Anhui Province sent 5 working groups to guide flood control work in various places.
The third is to start emergency response in time.
On June 30th 14, the National Defense General upgraded the emergency response to flood control from level IV to level III, and the Taihu Lake Defense General launched level II response, the Yangtze River Defense General launched level III response, and the Huaihe River Defense General launched level IV response to jointly cope with the floods in the basin.
Hubei, Hunan, Anhui, Jiangsu and Guizhou provinces launched flood control level III emergency response, and Chongqing and Henan provinces and cities launched flood control level IV emergency response to fully carry out flood control and rescue work.
The fourth is to scientifically dispatch water conservancy projects.
All localities actively take measures to control flood discharge, vacate reservoirs in advance to meet floods, and scientifically dispatch water conservancy projects.
The Three Gorges Reservoir of the Yangtze River pre-discharges 22 billion cubic meters of flood control storage capacity ahead of schedule. According to the outflow of 30,000 cubic meters per second, the No.1 flood of the Yangtze River this year has been effectively controlled, with the maximum peak clipping rate of 40% and the downstream water level reduced by 1 .5-2 meters.
Since entering Mei on June 19, Taihu Flood Control Headquarters has discharged 682 million cubic meters of Taihu Lake flood by dispatching Taipu sluice and water control project, and Jiangsu and Zhejiang provinces have used the Yangtze River and Hangzhou Bay to rob the river network of waterlogging16.77 million cubic meters, effectively slowing down the water level rise in rivers and lakes.
Dong Dawei flood storage and detention area was opened in Anhui Province, with 230 million cubic meters of flood storage and detention, which reduced the flood control pressure in Chaohu Lake. The peak clipping rates of Mozitan Reservoir, Meishan Reservoir and Xianghongdian Reservoir in Huainan City reached 87%, 9 1% and 87% respectively.
The flood control reservoir in Hubei Province has discharged 600 million cubic meters of flood water.
The fifth is to grasp danger and protection.
All localities have stepped up patrols and emergency support, quickly launched a military-civilian coordination mechanism, and scientifically handled various dangerous situations such as breaches, breakdowns, slopes, bank collapses, leakage and piping.
Anhui Province organized and mobilized 40,000 cadres and masses to inspect dikes, handled 374 dangerous situations and seized 65.438+77 billion cubic meters of drainage. In Hubei province, all parts of the country are rushing to drain accumulated water, and the total drainage of each pumping station is1.1.800 million cubic meters.
More than 5,600 cadres and masses, armed police and militia reserves in Wuhan spared no effort to protect them, effectively controlling the dangers of many people's markets.
The sixth is early warning transfer.
The six provinces (cities) of Zhejiang, Anhui, Hubei, Hunan, Chongqing and Guizhou have given full play to the role of the monitoring and early warning system and the group monitoring and prevention system for mountain torrents, and transferred the threatened people in time, with a cumulative emergency transfer of 6,543,800 people, thus avoiding and reducing casualties caused by floods and mountain torrents in small and medium-sized rivers.
Anhui Province transferred people 1002 in flood storage and detention areas in Dong Dawei ahead of schedule, with no casualties; More than 9,000 people in Hubei Province were safely transferred and properly placed due to breaches in many public places.
As of July 3, statistics show that 26 provinces (autonomous regions and municipalities) 1 192 counties in China have suffered from floods, with an area of 2,942 thousand hectares affected by crops, 32.82 million people affected, 480,000 people moved urgently 186 people died and 45 people were missing.
Compared with the average value of the same period since 2000, the affected area, affected population, dead population and collapsed houses are 6%, 33%, 47% and 76% less respectively, and the direct economic loss is 565,438 0% more.
It is estimated that there will be more precipitation in the whole country during the main flood season this year. The main rainy areas are located in Jiangnan, Jianghuai, Huanghuai, Southwest and Northeast China. The possibility of major floods in the Yangtze River, Songhua River and Huaihe River is high. The number of landing typhoons is small, but the intensity is strong. There may be a strong typhoon landing in China and going deep inland.
In the next 10 day, there will be two heavy rainfall processes, among which there will be heavy rains along the middle and lower reaches of the Yangtze River and the eastern part of southwest China, Jianghuai, southern Huanghuai and southern western South China, and some areas will have heavy rains on 2 ~ 4 days; From May 5 to 9, the main rainfall areas gradually moved northward to the north of Jianghuai, south-central Huanghuai, southwest and east, with moderate to heavy rain and heavy rain in some areas.
At 8 o'clock on the 3rd, this year'sNo. 1 typhoon "Nibert" formed in the east of the Philippines (about 1 10 days later than the No.1 typhoon all the year round) and approached the eastern coast of China.
Affected by it, there will be strong rainfall and windy weather processes in northern Fujian, Zhejiang, Shanghai and southern Jiangsu from July 7 to 8.
Affected by the continuous heavy rainfall in recent days, the water levels from Lianhuatang to Datong River, Dongting Lake and Poyang Lake in the middle and lower reaches of the Yangtze River will exceed the police within 3 to 5 days; The water level of Taihu Lake will exceed the guaranteed water level by 4.65 meters on the 3rd and continue to rise slowly. There may be a flood exceeding the warning water level in the middle and upper reaches of Huaihe River in the near future.
The flood control situation is grim.
At present, the flood control work in China has entered a critical stage.
In the next step, the National Defense General will proceed from the most unfavorable situation and the worst combination of rainfall and flood, carefully organize and arrange various defense work, further strengthen monitoring, early warning and forecasting, closely monitor the development and changes of rainfall, water regime and flood, carry out rolling analysis and forecasting, strengthen consultation and judgment, and be on emergency duty, scientifically and carefully dispatch flood control projects, do a good job in the investigation of hidden dangers in dikes, reservoirs, culvert gates, pumping stations and other buildings, and find dangerous situations in time.
According to the current flood situation in the basin and the possible heavy rainfall process, we will constantly improve various flood control measures, strictly implement the reservoir operation plan, reserve sufficient flood control capacity, and make every effort to prepare for the over-standard flood in the basin; Deploy rescue teams in advance and prepare enough relief materials.
The river basin defense headquarters and the local defense headquarters should further communicate closely, give full play to the comprehensive coordination, command and decision-making role of the river basin defense headquarters, focus on key tasks such as mountain flood prevention, reservoir safety flood control, urban flood control and drainage, timely transfer people in dangerous areas, ensure the safety of people's lives, and minimize disaster losses.
Strengthen communication with * * *, the Armed Police Force, and the military-civilian joint defense to jointly do a good job in flood control and disaster relief.
