What are the geological disasters in Guizhou?

Question 1: What are the characteristics of geological disasters in Guizhou Province? Guizhou province has special geological conditions and fragile geological environment. According to the National Geological Disaster Prevention and Control Plan, the whole province is one of the geological disaster-prone areas and hardest hit areas in China, with the characteristics of "all-round, heavy and many". According to the data analysis of geological disasters in 74 counties (cities) of Guizhou Province, there are 8 high-prone areas with an area of 38,000 km2, medium-prone areas 16, with an area of165,400 km2, and low-prone areas10.5 million km2 with an area of 23,000 km2. At present, 8905 geological disasters have been identified, including 66 18 hidden dangers threatening personal and property safety. According to statistics, from 2003 to 2007, there were geological disasters 1933 times in Guizhou province, and the direct economic loss was about 265 million yuan. 7 1 geological disasters were successfully avoided, 3,429 casualties were avoided and the economic loss was 82.92 million yuan.

Guizhou province is a region with serious geological disasters, which mainly has the following characteristics:

(1) Various types: Guizhou Province is located in the slope zone where the Yunnan-Guizhou Plateau transits to the hilly plain of Guangxi. The common types of geological disasters are landslide, collapse, debris flow, ground subsidence and ground fissure. Ground fissures in Guizhou are often the reflection of collapse, slip and collapse on the surface. Among them, the types of geological disasters that are most harmful to people's lives and property are mainly landslides, collapses and mudslides. Geological disasters in Guizhou province are mainly small and medium-sized (accounting for more than 90%), and large or giant disasters are rare. However, more than major geological disasters occur almost every year. Generally speaking, the scale of geological disasters caused by natural factors is small, while the scale of geological disasters caused by human factors is relatively large. Since 1993, there have been 58 major geological disasters in * * * in the whole province, including more than 30 deaths or economic losses of10/8, which are more or less caused by human factors.

(2) Wide distribution: From the geographical distribution, 9 places (prefectures and cities) in Guizhou Province have different degrees of geological disasters every year, but the most frequent ones are mainly concentrated in Zunyi, Bijie, Liupanshui, Southwest Guizhou and Tongren, and their distribution is closely related to geography, landform, geological structure, geotechnical structure and climate. According to statistical analysis, sudden geological disasters in the province mainly occur from May to September, with an average of 40-60 cases per month, accounting for 35-90% of the total number of geological disasters in the whole year, which is a period of high incidence of geological disasters; Followed by April and 10, the average number of geological disasters per month is about 10, accounting for about 5- 10% of the total number of geological disasters in the whole year, which is the middle period of geological disasters; During1-March,11-65438+February, there were 1-3 sudden geological disasters every month, accounting for 0.5- 1.0% of the total geological disasters in the whole year, which is a low-incidence period of geological disasters.

(3) Easily induced: According to statistics, the main inducing factors of geological disasters are the natural factors of atmospheric precipitation and the influence of human engineering activities. Because Guizhou is mostly mountainous and influenced by topography, the rainfall varies greatly between regions and seasons. In addition to mass geological disasters caused by general rainstorms, sudden geological disasters caused by local rainstorms are also a major feature of Guizhou Province. In engineering construction, due to the weak awareness of disaster prevention, people often unconsciously appear some unreasonable engineering activities in engineering construction, such as unreasonable planning and site selection, unrealistic engineering design, unreasonable slope cutting, sand mining, quarrying, groundwater exploitation and other man-made geological disasters are also prominent; With the increase of mineral resources development intensity, the surface movement and deformation of mining areas develop rapidly; Coupled with steep slope reclamation, vegetation destruction and other reasons, the unstable factors of geological bodies increase or intensify, and the hidden dangers of geological disasters show a rapid growth trend. In particular, Guizhou Province is rich in coal and other mineral resources. With the development of national economy and the rapid growth of resources development, geological disasters such as uneven ground settlement, ground collapse and ground fissures caused by mined-out areas have become increasingly prominent, and even further lead to slope instability, collapse, landslide and debris flow. All kinds of geological disasters in major mining areas have increased rapidly, and the number, scale, danger and harmfulness of hidden dangers have increased exponentially. The threatened population, threatened engineering facilities and property are increasing day by day, which is very harmful.

(4) Great impact: First, it caused casualties and significant economic losses. According to incomplete statistics, since 1993, there have been 50 12 sudden geological disasters in Guizhou province, including 237 casualties, 29 deaths 1090, and 29 missing persons, resulting in a direct economic loss of 2.398 billion yuan. Geological disasters occur once a year on average ... >> 3.

Question 2: What are the geological disasters in Guizhou Province, such as landslides, collapses, land subsidence, ground fissures and mudslides? Strong storm disasters, tornadoes, hail, snow condensation disasters, thunderstorms and thunderstorms.

Question 3:20 16 Guizhou Geological Disaster Prevention and Control Plan 20 16 How to compensate for the relocation of geological disasters in Guizhou Province?

According to the relevant provisions of the Regulations on the Prevention and Control of Geological Disasters (Order No.394 of the State Council) and the arrangement of the province, this plan is formulated in combination with the geological conditions of our province and the meteorological forecast for 20 16, in order to do a good job in the prevention and control of geological disasters in the whole province and avoid and reduce casualties and economic property losses caused by geological disasters to the maximum extent.

I prevention and control of geological disasters 20 15

In 20 15 years, there were * * geological disasters 163 in the whole province, with 27 deaths and direct economic loss1600,000 yuan. Compared with the same period of last year, the number of disasters decreased by 77.9%, the number of casualties decreased by 67.3%, and the direct economic loss decreased by 77.7%. Geological disasters in the province mainly have the following characteristics: First, natural inducing factors are the main factors, resulting in 157, accounting for 96.3% of the total number of disasters; Six cases were caused by human factors, accounting for 3.7% of the total number of disasters. Second, the scale is small, 130 cases, accounting for 79.8%; 26 cases were moderate, accounting for16.0%; Large and catastrophic disasters account for 3. 1% and 1. 1% respectively. Thirdly, landslide is the main disaster type, followed by collapse, debris flow, ground collapse and ground fissure, accounting for 75.5%, 19.0%, 1.2%, 2.5% and 1.8% of the total disaster respectively. Fourth, the disasters occurred mainly in June and August, with June being the most concentrated, and 63 geological disasters occurred in that month, accounting for 38.7% of the whole year; In August, geological disasters occurred in 5 1, accounting for 3 1.3% of the whole year. Fifth, in terms of spatial distribution, there are many geological disasters in Qiandongnan Prefecture, with 64 occurrences, accounting for 39.3% of the total number of disasters; Followed by Southwest Guizhou, there were 53 disasters, accounting for 19. 1% of the total number of disasters. Except Anshun City, Liupanshui City, Qiannan Prefecture and Qianxinan Prefecture, there were casualties in other cities (states).

In 20 15, the province invested a total of/kloc-0.06 billion yuan in special funds for the prevention and control of geological disasters, and comprehensively controlled 25 1 places of major hidden dangers of geological disasters. Solidly promote the governance of schools threatened by geological disasters and complete the relocation and governance of 238 schools threatened by geological disasters. Strengthen early warning and forecasting, * * * release geological disaster risk early warning information 170, send nearly1050,000 mobile phone messages, successfully predict and avoid 29 sudden major geological disasters, avoid 4,983 casualties and economic losses1200,000 yuan. Comprehensive rotation training was conducted for more than 500 township land offices and more than 2,600 township land offices in the province/KLOC-0, to improve the professional ability of geological disaster prevention and control. The hidden danger points of 1226 1 have been completely covered, and the geological disaster emergency drill has been completed. Completed the construction of 49 high-standard "ten counties" and was named by the Ministry of Land and Resources. The provincial geological disaster emergency technical guidance center was established, which realized the "three in place" of personnel, equipment and technology.

Two. Geological hazard prediction 20 16

According to the occurrence and development law of geological disasters in our province in recent years, considering the frequent occurrence of extreme weather and other factors, the occurrence rate of geological disasters in our province will still be high in 20 16 years, in which sudden geological disasters account for the main proportion, mainly caused by rainfall, mainly distributed in the peak period of May-September and June-August in the flood season.

(1) Forecast of major regions. Geological disasters are prone to occur in northern Zunyi, south-central Bijie, Liupanshui, western and southern Anshun, tongren city, northern and western edge of Qiandongnan Prefecture, eastern Qiannan Prefecture and northern Qianxinan Prefecture.

(2) Main mine prediction. The western part of our province is characterized by deep terrain cutting, complex landform combination characteristics, uneven lithology of soft and hard strata, frequent engineering activities, mainly coal mining, and is a high-risk area of geological disasters.

(3) Forecast of main traffic arteries. The railway mainly runs along the Guizhou sections such as Sichuan-Guizhou, Hunan-Guizhou, Guizhou-Guangxi, Neikun, Guikun, Shuibai and Nankun. The highways are mainly national highways such as G32 1, G326, G2 10, G320, and Guizhou sections of Guiguang, Zunchong, Huangshui, Qingzhen, Guixin, Guanxing, Guibi, Kaima, Zhensheng and Guizun expressways. And the possibility of geological disasters such as landslides and collapses in the areas of high-speed rail and expressway projects under construction.

(4) Forecast of important projects. The population in the north and northeast of our province is relatively dense, and the coal bases under construction, mines, reservoirs (hydropower stations) and existing reservoirs (hydropower stations) are relatively concentrated, resulting in landslides. & gt

Question 4: Is there any possibility of other natural disasters and natural geological disasters in Guiyang? Which area is safer, Guizhou Province or Guiyang? 10. What do you mean? No place on the whole earth is absolutely safe. Theoretically, the probability of an earthquake in Wenchuan a few years ago was very small, but it still happened. In other words, the capital of China can be said to be the place with the highest safety factor, but 7.2 1 died because of heavy rain 10 people. Natural disasters are irresistible to mankind. Don't think about those useless things, where it is safe and where it is not safe. The safest place is where you have your own family and relatives.

Question 5: Have there been any major geological disasters in Anshun, Guizhou?

Event classification

According to the severity and urgency of sudden geological disasters, sudden geological disasters are divided into four grades: super-large (Grade I), large (Grade II), medium (Grade III) and small (Grade IV):

(1) Extraordinary geological disaster (Grade I): more than 30 people died or the direct economic loss was more than100000 yuan;

(2) Large-scale geological disaster (Grade II): more than 10 people (including 10 people) but less than 30 people died or the direct economic loss was more than 5 million yuan (including 5 million yuan) but less than100000 yuan;

(3) Medium-sized geological disasters (Grade III): more than 3 people (including 3 people)/less than 0/0 people died or direct economic losses/more than 0/00000 yuan (including/0/00000 yuan) but less than 5 million yuan;

(4) Small geological disasters (Grade IV): less than 3 people died or the direct economic loss was less than 6,543,800 yuan.

Question 6: What geological disasters have occurred in Bijie, Guizhou?

Guizhou Province is a region with serious geological disasters, which mainly has the following characteristics: (1) There are many kinds: Because Guizhou Province is located in the slope zone where the Yunnan-Guizhou Plateau transits to the hilly plain of Guangxi, the common types of geological disasters are landslide, collapse, debris flow, ground subsidence and ground fissures. Ground fissures in Guizhou are often the reflection of collapse, slip and collapse on the surface. Among them, the types of geological disasters that are most harmful to people's lives and property are mainly landslides, collapses and mudslides. Geological disasters in Guizhou province are mainly small and medium-sized (accounting for more than 90%), and large or giant disasters are rare. However, more than major geological disasters occur almost every year. Generally speaking, the scale of geological disasters caused by natural factors is small, while the scale of geological disasters caused by human factors is relatively large. Since 1993, there have been 58 major geological disasters in * * * in the whole province, including more than 30 deaths or economic losses of10/8, which are more or less caused by human factors.

(3) Easily induced: According to statistics, the main inducing factors of geological disasters are the natural factors of atmospheric precipitation and the influence of human engineering activities. Because Guizhou is mostly mountainous and influenced by topography, the rainfall varies greatly between regions and seasons. In addition to mass geological disasters caused by general rainstorms, sudden geological disasters caused by local rainstorms are also a major feature of Guizhou Province. In engineering construction, due to the weak awareness of disaster prevention, people often unconsciously appear some unreasonable engineering activities in engineering construction, such as unreasonable planning and site selection, unrealistic engineering design, unreasonable slope cutting, sand mining, quarrying, groundwater exploitation and other man-made geological disasters are also prominent; With the increase of mineral resources development intensity, the surface movement and deformation of mining areas develop rapidly; Coupled with steep slope reclamation, vegetation destruction and other reasons, the unstable factors of geological bodies increase or intensify, and the hidden dangers of geological disasters show a rapid growth trend.

All kinds of geological disasters in major mining areas have increased rapidly, and the number, scale, danger and harmfulness of hidden dangers have increased exponentially. The threatened population, threatened engineering facilities and property are increasing day by day, which is very harmful. (4) Great impact: First, it caused casualties and significant economic losses. According to incomplete statistics, since 1993, there have been 50 12 sudden geological disasters in Guizhou province, including 237 casualties, 29 deaths 1090, and 29 missing persons, resulting in a direct economic loss of 2.398 billion yuan. On average, there are 358 geological disasters every year, with about 17 casualties, 80 deaths and direct economic losses close to 200 million yuan. The second is to destroy towns, mines and enterprises. Frequent geological disasters have destroyed a large number of urban and rural building facilities, cultivated land, factories and traffic trunk lines. Such as Dafang landslide at the source of Wujiang River, Sinan landslide, Shiqian landslide and Yanhe landslide in the middle reaches, Yankou landslide and Shanshan landslide in Yinjiang County, and Datong landslide in Chishui. , large scale, serious harm. The third is to destroy railways, highways and waterways and threaten traffic safety. Such as 1 June 65438+ 1 day, 22 people died, 13 people were missing,1bridge was destroyed, and the economic loss was100000 yuan; On May 0, 2003, at 1 1 55, a landslide occurred near Pier 3 of Pingxi Bridge on Sansui-Kaili Expressway in Tailie Village, Sansui County, Qiandongnan Prefecture, causing 3 ... & gt

Question 7: Four natural disasters in Guizhou Province? Five-minute drought

geologic hazard

snow disaster

hail

Question 8: What are the main types of disastrous weather for agricultural production in Guizhou? Freezing, hail, drought without rain, flash floods and heavy rains are the most common disasters, needless to say! Are agricultural failures or failures.

Question 9: What meteorological disasters are there in Guizhou? 1. Severe storm disasters (tornado, hail, thunderstorm and thunderstorm, etc. ): The Geng disaster is mainly caused by extreme strong convective weather, which has little influence, but it is strong, sudden and harmful. For example, on February 20 this year, Shuangliu Forest Farm in Kaiyang County was hit by a strong wind. In the dense forest, many trees were broken by the waist, and some were uprooted and fell to the northeast. More than ten thousand trees were destroyed, covering an area of several hundred mu, resulting in direct economic losses of several hundred thousand yuan. The fallen trees crushed the nearby high-voltage line, and a ranger was almost injured. This incident is similar to the wind disaster in Xi Du Forest Farm on1October 30th. 1994+065438.

2. Rainstorm and flood: The flood caused by rainstorm is the most influential and fastest-growing disaster. Modern floods are characterized by high frequency, wide influence range, long duration and great disaster intensity. For example, in196, the catastrophic flood disaster caused crops to suffer17.54 million mu, and the economic loss was as high as160 billion yuan. The disaster caused the flood peak of Nanming River in Guiyang to exceed the warning water level by 2.83 meters. The roaring river raged in the low-lying areas along the river, and many bridges on the Nanming River in the urban area were washed away. The guardrail and deck of Jiaxiulou Bridge were washed away at the flood peak, and the river turned over Jiaxiulou Bridge. Many low-lying streets in the urban area are already in Wang Yang, and the moat in the city has been submerged; The Guanshui Lane on the left side of Jiaxiu Building is nearly 2 meters deep, and many dormitory workers nearby are besieged 14 hours.

3. Drought: Drought caused by less rainfall is the main meteorological disaster that plagues agricultural development in Guizhou. According to statistics, the affected area in Guizhou 1949- 1990 was 389.25 million mu, with the third disaster rate in China and the first in the south. For example, 1996 suffered a hundred days of drought in winter and spring. From February last year to March of that year, crops in the province were affected by 338,000 hectares, resulting in 205,000 hectares of disasters, with a total harvest of 6,543,807 hectares, a reduction of 6,543,802,000 tons of grain production and 8,000 tons of oil production, resulting in 76.26 million people and 76,000 people.

4. Cold damage (spring cold, autumn wind, freezing, snowstorm, etc. ): It has a great impact on agricultural production, transportation and so on. Among them, the autumn wind is an agricultural meteorological disaster in which the booting stage of rice occurs for three consecutive days from August to early September, and the daily average temperature is lower than 20 degrees, which leads to an increase in rice empty shell rate and a decrease in yield. For example, since August 9, 2002, the continuous low temperature and rainy weather in most parts of the province lasted for 5 ~ 12 days, resulting in the reduction of grain production in the province by 2 1%, which is the heaviest autumn wind year in our province. Another example is the snowfall of +65438 on February 25, 2002, which caused all long-distance and short-distance buses in Guiyang bus station to stop running, the airport was forced to close, traffic was paralyzed, and many traffic accidents occurred, and more than 50 people suffered from slips and fractures. The impact of snowfall on transportation, power supply, communication and water supply industries is more obvious in higher terrain areas.
