General situation of flood and geological disasters:

In 2014, Honggang and geological disasters caused 72.0001 million person times of disasters in 29 provinces (autonomous regions and municipalities directly under the central government), 631 people died, 97 people were missing, and 3.47 million people were urgently transferred and resettled; 269,000 houses collapsed and 1.231 million were damaged to varying degrees; the disaster area of crops was 47389000 hectares, of which 6282000 hectares were lost, and the direct economic loss was 102.98 billion yuan.

In 2014, flood and geological disasters mainly showed the following characteristics:

1.Frequent extreme weather, severe disaster in southern China

In 2014, extreme weather occurred frequently in China, and mainly concentrated in the southern region. 23 heavy rainfall events occurred in the whole year, and the duration of autumn rain in West China was as long as 20 days. Among them, the daily precipitation in Xinshao of Hunan Province and Conghua of Guangdong Province broke through the historical extreme value in May; In the middle of July, the daily precipitation in Guiyang and Qingzhen, Guizhou, and the continuous precipitation in Jishou, Hunan and Yinjiang in Guizhou broke through the historical extreme value; In September, the accumulated rainfall in Bazhong, Dazhou and Hanzhong of Shaanxi exceeded 500mm, more than half of the average annual rainfall; The precipitation in some areas of East China and southwest China is 20-30% more than that of the whole year, and that of Jialing River and Hanjiang River is 1.3-1.6 times more than that of the same period of the year; A total of 343 rivers have exceeded the warning water level, 62 rivers have exceeded the guaranteed water level, and 21 rivers have exceeded the historical record level flood, which are mainly distributed in the southern region. Eight provinces (autonomous regions and municipalities directly under the central government) including Jiangxi, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou and Yunnan have suffered severe disasters, the number of people affected by the disaster, the people who died and disappeared due to the disaster, the population who needed emergency living assistance, and the number of houses damaged accounted for more than 70% of the whole country; More than 60% or nearly 60% of the crops were affected by the disaster, caused by disasters and no harvest.

2.The factors of disaster and poverty are obviously superimposed, and the urban disaster situation is prominent

In 2014, 30% of China's key counties in poverty alleviation and development work in disaster stricken counties (cities and districts) accounted for 30%, and the number of dead and missing persons and damaged houses accounted for more than 40% of the total loss in China. Affected by extreme rainfall, 483 counties (cities, districts) were affected by the extreme rainfall, especially the waterlogging in some urban areas in southern China, which greatly affected people's production and living, transportation and infrastructure. In late May, 13 sections of 5 national highways and 136 sections of 27 provincial roads in Guangdong were destroyed by heavy rainfall. Shenzhen suffered the strongest rainstorm since 2008, with water accumulated on 150 roads in the city, and many flights were cancelled; At the end of May, waterlogging occurred in Hengyang, Huaihua and Fenghuang ancient city, which had a great impact on local tourism; At the beginning of June, 60% - 80% of the urban areas such as Daya Bay in Guangdong, Fengshan in Guangxi and Shiqian in Guizhou were inundated. In the middle and late June, the maximum water depth was 3 meters in Mayang and Shaodong counties of Hunan Province; In the whole year, 62 times of railway interruption, 34000 times of highway interruption, 14000 times of power supply line interruption and 12000 times of communication line interruption were caused by the disaster.

3.The geological disasters are concentrated in Southwest China, and the single casualties are relatively large

In 2014, a total of 109 counties (cities and districts) were affected by mountain collapse, landslides, debris flows and other geological disasters to varying degrees, distributed in 15 provinces (autonomous regions and municipalities directly under the central government).

The most serious disaster occurred in Southwest China, with 79.8% of the total counties affected by geological disasters. More than 90% of the country's total number of people were resettled in emergency and houses were damaged, and more than 70% were dead and missing. Among them, Gaoyao City, Guangdong Province, on March 30, a landslide caused by heavy rainfall, killing 6 people; At 9:20 on June 30, a landslide occurred in Fugong County, Yunnan Province, killing 15 people; On July 9, debris flows occurred in Fugong and Yunlong counties of Yunnan Province, killing 31 people; On July 16, a number of landslides occurred in Anhua County, Hunan Province, killing 20 people; On July 17, a mountain collapse occurred in Maoxian County, Sichuan Province, killing 10 people, the deaths and missing persons caused by the above events account for about 50% of the total number of people in the whole year.
