Compared with the same period in 2006, there were 466 natural disasters in China from June to July this year, the frequency of which was much higher than that in the same period in 2006. In particular, extreme weather and climate events have caused very serious casualties and economic losses to the affected areas. The area affected by crops increased by 0.75% compared with the same period in 2006, and the area where crops were not harvested increased by 5.28%. However, this year, there have been gratifying phenomena of "great water situation, little danger" and "heavy disaster and light loss". Among them, the population of emergency resettlement decreased by 38.4%; The number of deaths and missing persons decreased by 22.9%; The number of collapsed houses decreased by 38.8%; Direct economic loss decreased 15.45%. The main reason is that the disaster relief ability has been greatly enhanced; Disaster prevention and mitigation projects and facilities to play a benefit; The quality of people's housing has improved. Since the beginning of this year, the national disasters have mainly shown the following characteristics: (1) Multiple disasters are concurrent, and floods and droughts have caused heavy losses. Since the beginning of this year, floods, droughts, wind and hail, earthquakes, landslides, mudslides, tornadoes, lightning strikes, low-temperature freezing and snowstorms have all occurred to varying degrees, among which floods and droughts are particularly serious. As of July 3 1 day, the flood disaster in China caused10.2 billion people to be affected, 936 people died and 5.24 million people moved. The affected area of crops is 65.438+0.2 billion mu, and the area of no harvest is 20.83 million mu; There were 608,000 houses collapsed, and the direct economic loss was 6157.2 million yuan. Among them, Anhui, Sichuan, Chongqing, Hubei, Henan, Yunnan, Shaanxi and other provinces have serious floods; The droughts in Liaoning, Jilin, Heilongjiang, Hunan, Jiangxi, Guangdong, Fujian and Zhejiang are serious. (2) There are many points and wide areas, and the repeated disaster area is large. Since the beginning of this year, 3 1 provinces and Xinjiang production and construction corps have been affected to varying degrees, of which 27 provinces have suffered from floods, landslides and mudslides, 25 provinces have suffered from drought, 26 provinces have suffered from wind and hail, and a devastating earthquake of magnitude 6.4 occurred in Yunnan. Many provinces in southwest and central China have suffered from repeated disasters, especially Sichuan and Chongqing. Last year, they suffered a once-in-a-century drought, and this year, a serious spring drought occurred. After entering the flood season, drought and flood turned sharply, and several severe storms and floods occurred in succession. Since late May, there have been 12 floods in Sichuan, 10 floods in Hubei, and 6 floods in Chongqing, which are rare in the same period in history. (3) Abnormal climate and frequent extreme weather events. Affected by global warming, China's climate is abnormal this year, and extreme weather and climate events occur frequently. The first is the once-in-a-century snowstorm. At the beginning of March, the northeast of Liaoning was hit by a severe snowstorm, which caused traffic paralysis in Shenyang and Anshan, Liaoning Province, and power and water were cut off in Dalian. Second, the summer drought is serious. In June, the worst summer drought in 30 years occurred in Liaoning and Jilin. Since July, a severe summer drought has occurred in parts of Northeast China, Jiangnan and South China. Third, the local rain is beyond history. On July 16, Chongqing suffered the biggest rainfall since 2005, and on July 18, Jinan suffered the biggest rainstorm since meteorological records were recorded. In July, the rainfall in the Huaihe River basin was second only to 1954, which triggered a basin flood. Fourth, frequent wind disasters such as tornadoes. Jiangsu, Zhejiang, Anhui, Shandong, Hubei, Tianjin, Hebei and other places were hit by tornadoes, and the tornado in Gaoyou City, Jiangsu Province in early July was rare for 50 years. The super gust of Turpan 13 in Xinjiang caused the passenger train to derail and roll over1/KLOC-0. Fifth, the death toll from lightning strikes is rare in recent years. Since the beginning of this year, 369 people have been killed by lightning, accounting for 28.9% of the total number of people killed by disasters this year. In June, 45 people were killed by lightning in a disaster in Jiangxi Province, and 18 people were killed by lightning in July 6, which is rare in history. Sixth, the south continues to experience high temperatures. The average temperature in Shanghai in July reached 30.4 degrees Celsius, the historical extreme since 1873. Fuzhou has a continuous high temperature of 32 days, which is the most continuous high temperature days since 1880 has meteorological records. (four) the city was seriously affected, and the economic and social impact was deep. Compared with previous years, this year's urban disaster is more prominent. The severe snowstorm in early March caused nearly 300 long-distance passenger flights in Shenyang to stop, nearly 100 flights were blocked, many highways were closed, 44 towns in the city/kloc-0 were affected, and more than 5,000 houses collapsed and damaged. Blizzard has seriously affected the production and life of Shenyang, Dalian, Anshan and other cities. After the flood season, heavy rains flooded some large and medium-sized cities and hundreds of towns. In particular, Chongqing and Jinan, two major cities, were hit by heavy rains and suffered serious losses. The maximum water depth in Shapingba District of Chongqing is 4 meters, and Bishan and Tongliang counties are surrounded by floods. The whole city of Jinan was flooded, and the water depth in some areas exceeded 2.5 meters, resulting in 37 deaths, economic losses of nearly 100 million yuan, and serious damage to public facilities such as urban transportation, communication and electricity. Many small and medium-sized cities, such as Guang 'an City in Sichuan and Nayong County in Guizhou, also suffered serious losses.
