Recently, the Ministry of Emergency Management, together with the Ministry of Natural Resources, the Ministry of Water Resources, the Ministry of Agriculture and Rural Affairs, and the Meteorological Bureau, conducted a consultation analysis of the national natural disaster situation in the first half of 2020. It was verified that in the first half of the year, natural disasters throughout the country were mainly floods, hailstorms, and geological disasters. Forest fires, earthquakes, droughts, low-temperature freezing, and snow disasters also occurred to varying degrees. Various natural disasters caused a total of 49.609 million disasters, 271 deaths and disappearances, and 913,000 emergency relocations; 19,000 houses collapsed and 785,000 houses were damaged to varying degrees; the area affected by crops was 61,702 thousand hectares; direct economic losses were 81.24 billion yuan . Compared with the same period of last year, the number of people affected by the disaster increased by 41.5%, the number of people missing due to the disaster and the number of collapsed houses decreased by 26.2% and 53.7% respectively, and the direct economic loss increased by 15.3%. Compared with the average of the same period in the past 5 years, the number of victims, the number of people missing due to the disaster, the number of collapsed houses and the direct economic loss decreased by 18.6%, 32.4%, 75.6% and 16.9% respectively.
The average precipitation in the country and the inflow of rivers are generally more, and the floods of small and medium rivers and local flash floods have a greater impact
In the first half of the year, the national average precipitation (275.9 mm) was 7% more than the same period of the normal year. The pre-flood season in South China (March 25) and the Meiyu period in Jiangnan (June 1) were 12 days and 7 days earlier than the normal year. 14 times of regional rainstorm process; the main rivers have more incoming water, and 309 rivers in 19 provinces (autonomous regions and municipalities) have super-alarm floods, of which 45 rivers have super-protection floods and 12 rivers have super-historic floods. According to statistics, in the first half of the year, flood disasters caused 17.707 million people in 26 provinces (autonomous regions and municipalities), 119 people died and disappeared, 848,000 people were transferred and resettled, 15,000 houses collapsed, and direct economic losses amounted to 39.31 billion yuan. Compared with the average value of the same period in the past five years, the number of people affected by floods and floods, the number of people missing due to disasters, the number of collapsed houses and the direct economic loss decreased by 37%, 43%, 75% and 27%, respectively. In addition, in the first half of the year, two typhoons were generated in the Northwest Pacific and the South China Sea, and one of them (Typhoon No. 2 this year) landed in my country, with less impact of wind and rain.
Small and medium-sized geological disasters occur frequently, and the central and southern regions are more prominent
In the first half of the year, there were no single geological disasters in the country that caused more than 10 deaths and disappearances, mainly small and medium-sized geological disasters. Especially since May, regional heavy rainfall has caused a large number of geological disasters in Jiangxi, Guangdong, Guangxi, Yunnan, Guizhou, Sichuan and other places. There were 1351 geological disasters nationwide, and 46 people died or disappeared due to geological disasters caused by natural factors. Compared with the same period of many years, the geological disasters in the central and southern regions have the largest number of deaths and deaths due to disasters, and the direct economic losses in the southwest region have caused the most losses. In general, the casualties caused by geological disasters in the first half of the year were significantly lighter than in the same period of previous years.
Hail disasters are widespread and there are frequent lightning strikes
In the first half of the year, 28 regional short-term heavy rainfall, thunderstorms, strong winds and hailstorms occurred in the country, which was the same as the average of the same period in the past five years and four times more than the same period last year. The wind and hail in the northern region is mainly dominated by strong convective weather such as high winds and hail, which causes heavy losses to crops. The wind and hail in the southern region is mainly dominated by strong convective weather such as short-term heavy rainfall and thunderstorms. Yunnan, Hainan, Guangxi and other provinces (autonomous regions) have the most average annual thunderstorm days. According to statistics, in the first half of the year, the hail disaster caused 10.903 million people in 29 provinces (autonomous regions and municipalities) to be affected by 1,090.3 million people, 65 people were missing and missing (including 30 people killed by lightning strikes), and 36,000 people were urgently resettled. Damaged houses, 1595.8 thousand hectares of crops affected area, direct economic loss of 18.79 billion yuan. Compared with the average value of the same period in the past five years, the number of people affected by hail disasters and the number of people missing due to disasters fell by 14% and 26% respectively. The number of damaged houses and direct economic losses increased by 46% and 28% respectively.
The frequency of forest fires is declining, and the spatial and temporal distribution is relatively concentrated
In the first half of the year, the nationwide field fire source special control action has achieved remarkable results, and the number of forest and grassland fires has dropped significantly, the least in the same period in the past 10 years. A total of 806 forest fires occurred throughout the country, with an area of 5,387 hectares of affected forests. 37 people were killed or injured (34 of them died) due to forest fires. In terms of time, forest fires concentrated in March and April, accounting for 59% of the total in the first half of the year. From a regional perspective, Guangxi, Sichuan, Shaanxi, Yunnan, Guangdong, Hunan, Hubei and other places have more fires, accounting for more than 60% of forest fires in the country.
There are many moderate to strong earthquakes in the western region, and the disaster losses are relatively light
In the first half of the year, there were 17 earthquakes of magnitude 5.0 and above (15 earthquakes of 5.0-5.9 and 2 earthquakes of 6.0-6.9) in mainland China, which was higher than the same period in history, mainly in remote areas of Xinjiang, Tibet, Sichuan and Yunnan , No major casualties and property losses were caused. Among them, on January 19, a 6.4 magnitude earthquake in Xinjiang Jiashi caused 100,000 people to be affected in 7 counties (cities) in Kashgar region, 1 person was killed, more than 800 houses collapsed, and 109,000 houses were damaged; An earthquake of magnitude 5.0 caused 11,000 people to be affected in Ludian County and Qiaojia County of Zhaotong City, 4 people were killed, and more than 1,100 houses were damaged to varying degrees. On June 26, a magnitude 6.4 earthquake occurred in Yutian County, Xinjiang. The epicenter was high and the population nearby was sparse. There was no damage to the house and casualties.
The drought disaster has obvious stage characteristics. Winter and spring drought in Yunnan and local spring and summer drought in North China and Northwest China are intertwined.
In the first half of the year, drought disasters affected 11.645 million people in 14 provinces (autonomous regions and municipalities) such as Yunnan, Sichuan, Shanxi, Shaanxi, and Inner Mongolia. 2.03 million people were rescued due to drought. The area affected by crops was 20.53 million hectares, and drinking water was 1.99 million. Head (only), direct economic loss of 6.59 billion yuan. Affected by factors such as low total precipitation and uneven spatial and temporal distribution, in the first half of the year, there was less river water in Yunnan Province and less reservoir storage. At the peak of drought, there were 137 river channels in the province, 201 reservoirs were dry, and 4.985 million people As a result of the disaster, 1.592 million people needed assistance for drought. The area affected by the crops was 733 thousand hectares, with a direct economic loss of 2.67 billion yuan, accounting for nearly 40% of the national losses due to drought. Since April, Shanxi, Shaanxi, Inner Mongolia and Xinjiang have experienced continuous high temperature and low rainfall. As of the end of June, the moderately meteorological drought area in 4 provinces (regions) has reached 939,000 square kilometers. weight.
Northwest China and North China suffered greatly from low temperature freezing, and disaster losses were heavy
In the first half of the year, there were 17 cold air processes throughout the country, which was more than the same period in normal years. Among them, two cold air processes in early April and mid-April caused large-scale cooling and snowfall processes in the northwest, north China and Shandong areas. The lowest temperatures in Weifang, Shandong, Zhangjiakou, Hebei, Chengde, and Shanxi fell below zero. As a result, a large area of fruits and vegetables and other crops were frozen, and 698 thousand hectares of crops in 6 provinces (autonomous regions) including Shandong, Hebei, Shanxi, Shaanxi, Gansu, and Ningxia were affected. Among them, 189 thousand hectares failed to harvest, and the direct economic loss was 9.66 billion yuan. Compared with the average of the same period in the past five years, the nationwide low-temperature freezing and snow disasters were relatively severe in the first half of the year, and the crop area and direct economic loss increased by 53% and 3%, respectively.
