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.
Annual disaster index of flood and geological disasters:
The closer to the dark blue area, the higher the annual disaster
index of flood and geological disasters.
The closer to the light blue area, the lower the annual disaster
index of flood and geological disasters.
The gray area in the figure indicates: Non affected areas.
