Recently, the Ministry of Emergency Management and the Ministry of Industry and Information Technology, the Ministry of Natural Resources, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, the Health Commission, the Statistics Bureau, the Meteorological Bureau, the Banking Regulatory Commission, and the Food and Reserve Bureau , Forestry and Grass Bureau, China Red Cross Society, National Railway Group and other departments and units conducted consultation and analysis on the national natural disasters in the first three quarters.
In the first three quarters, my country’s natural disasters were complex and severe. Extreme weather and climate events were frequent. Natural disasters were mainly floods, hail, drought, typhoons, earthquakes and geological disasters, as well as freezing and snow disasters, sandstorms, forest and grassland fires, marine disasters, etc. It also happened to varying degrees. A total of 94.94 million people were affected by various natural disasters, 792 people were killed and missing, 5.262 million people were relocated in emergency; 157,000 houses collapsed and 1.751 million were damaged to varying degrees; crops affected an area of 10583 thousand hectares; direct economic losses were 286.4 billion yuan. Compared with the average of the same period in the past five years, the number of people affected by the disaster, the number of dead and missing due to the disaster, the number of collapsed houses, and the direct economic loss have decreased by 31%, 14%, 16%, and 14%, respectively.
The main characteristics of natural disasters nationwide in the first three quarters are:
1. The stage characteristics of the disaster are obvious, and the disaster losses in northern provinces are heavy
In the first three quarters, the staged characteristics of natural disasters in my country were obvious. In terms of the distribution of the hardest-hit provinces, due to the early and stronger rainy season in the north this year, the late and weaker rainy season in the south, and the small number of typhoons landing, the disaster losses in the northern provinces are significantly higher than in the south.
2. There are many extreme heavy rainfall processes, and the loss of flood disasters accounts for a high proportion
In the first three quarters, there were 39 heavy rainfall processes in China, with 582 millimeters of precipitation across the country, which was 4% more than the same period in normal years. The areas in the western northeast, the southern east of North China, and the northwest of Huanghuai area are more than 40% to 90%, and the areas of northwestern, east and west of South China are less than 30% to 70%. A total of 533 rivers in 27 provinces (autonomous regions and municipalities) including Heilongjiang, Inner Mongolia, Henan, Chongqing, Sichuan, and Jiangxi experienced floods above the warning level.
Flood disasters present the following characteristics: First, there are many extreme heavy rainfall processes and strong disasters. Second, the large rivers are generally stable, with frequent floods in small and medium-sized rivers. Third, the situation in the autumn flood season is severe. In addition, according to preliminary statistics, a total of 3,625 geological disasters occurred across the country in the first three quarters, mainly from May to September, with heavy losses in the central and southwestern regions.
3. Wind and hail disasters have a wide range of impacts, and extreme convective weather causes casualties
In the first three quarters, there were 41 regional strong convective weather processes in my country. The number is less than the average value of the past five years, but the impact is wide and extreme. From the time point of view, before mid-April, the strong convective weather has been less and weaker. After mid-April, severe convective weather increased significantly, mainly in the northern part of Jiangnan, Jianghan, Jianghuai, North China, Huanghuai, Northeast and other places. In terms of intensity, there are obviously more extreme convection phenomena such as tornadoes. In terms of scope, a total of 1,235 counties (cities, districts) across the country were affected by wind and hail disasters in the first three quarters. It was the most widely affected type of disaster, causing 15.92 million disasters. The affected area of crops was 2381 thousand hectares, and the direct economic loss was 219.9. 100 million yuan.
4. Drought disasters are lighter than previous years, and droughts in southern China are emerging and developing
In the first three quarters, the stage characteristics of drought disasters were obvious. In general, the drought disaster in the first three quarters caused 17.33 million disasters in 23 provinces (autonomous regions and municipalities) including Shanxi, Shaanxi, Gansu, Yunnan, Inner Mongolia, and Ningxia. The affected area of crops was 3080 thousand hectares, and the direct economic loss was 17.73 billion yuan.
5. The number of typhoons landing is small, and the “fireworks” typhoon has a wide range of influence
In the first three quarters, a total of 16 typhoons were generated in the Northwest Pacific and South China Sea, 2.5 less than the average over the same period in many years. Among them, 3 typhoons made landfall in my country. In general, the typhoon losses in the first three quarters were the lowest in the same period in the past five years, causing 5.67 million disasters and direct economic losses of 28.08 billion yuan.
6. Seismic activity is relatively strong, and strong earthquakes have occurred in many parts of the west
In the first three quarters, there were 17 earthquakes of magnitude 5 or higher in my country’s mainland, mainly in western regions such as Xinjiang, Tibet, Qinghai, Yunnan, and Sichuan. In general, the earthquake disaster in the first three quarters caused 453,000 people in 14 provinces (autonomous regions and municipalities) to be affected, 9 people died, 62,000 houses collapsed and severely damaged, and a direct economic loss of 8.2 billion yuan.
7. Low temperature freezing and snow disasters occurred concentratedly at the beginning of the year, causing losses to local agriculture
In the first three quarters, low-temperature freezing and snow disasters mainly occurred at the beginning of the year, with heavy losses in January and April. In general, the low-temperature freezing and snow disasters in the first three quarters were lighter than normal, causing 2.82 million people to be affected, 287 thousand hectares of crops were affected, and a direct economic loss of 5.6 billion yuan.
8. Forest and grassland fires are distributed in time and space, and the overall situation is stable
According to preliminary statistics, a total of 527 forest fires occurred nationwide in the first three quarters. The affected forest area was about 2,628 hectares and 15 people died. There were 12 grassland fires, and the affected grassland area was about 3388 hectares, with no casualties. Compared with the average of the same period in the past five years, the number of forest fires and grassland fires decreased by 73% and 67%, respectively. Forest fires are concentrated in time and space. From a time point of view, forest fires occurred mainly from January to April; from a regional point of view, the 7 provinces (districts) of Guangdong, Guangxi, Yunnan, Fujian, Hunan, Jiangxi, and Hubei are areas where forest fires are frequent.
