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 prone to geological disasters, and it is one of the hardest hit areas in China, with the characteristics of "all-round, heavy and many". According to the investigation data of 74 counties (cities) in Guizhou Province, there are 8 high-prone areas with an area of 38, km2, 16 medium-prone areas with an area of 115, km2, and 1 low-prone areas with an area of 23, km2. At present, 8,95 geological hazards have been identified, including 6,618 hidden dangers that pose a threat to people and property. According to statistics, from 23 to 27, there were 1933 geological disasters in Guizhou province, and the direct economic loss was about 265 million yuan. 71 geological disasters were successfully avoided, and 3,429 casualties and economic losses of 82.92 million yuan were avoided.

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 fissure. The ground fissures in Guizhou are often a 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 9%), and there are few large or giant ones. However, almost every year, geological disasters of magnitude above major occur. Generally speaking, the scale of geological disasters caused by natural factors is small, while the scale of geological disasters caused by human beings is relatively large. Since 1993, there have been 58 geological disasters of major magnitude or above in the whole province, including 18 catastrophic disasters with more than 3 deaths or economic losses of more than 1 million yuan, all of which are more or less influenced by human factors.

(2) Wide distribution: In terms of geographical distribution, nine provinces (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, the sudden geological disasters in the whole province mainly occur from May to September, with an average of 4-6 sudden geological disasters per month, accounting for 35-9% of the total number of geological disasters in the whole year, which is a high incidence period of geological disasters; Followed by April and October, with an average of about 1 geological disasters per month, accounting for about 5-1% of the total number of geological disasters in the whole year, which is the middle period of geological disasters; During January-March and November-December, there are 1-3 sudden geological disasters every month, accounting for .5-1.% of the total number of geological disasters in the whole year, which is a low-incidence period of geological disasters.

(3) easy to induce: 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, there are great differences in rainfall in regions and seasons. In addition to the mass geological disasters caused by general rainstorm, sudden geological disasters caused by local rainstorm 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 human-induced geological disasters are also prominent; With the increase of mineral resources development intensity, the surface movement and deformation in the mining area 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 trend of rapid growth. In particular, Guizhou Province is rich in coal and other mineral resources. With the development of national economy, the development of resources has increased at a high speed, and 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 are growing rapidly in major mining areas, and the number, scale, danger and harmfulness of hidden danger points are increasing exponentially, and the threatened population, threatened engineering facilities and property are increasing, which is very harmful.

(4) Great impact: First, it caused casualties and heavy economic losses. According to incomplete statistics, since 1993, there have been 512 sudden geological disasters in Guizhou province, including 237 casualties, 19 deaths and 29 missing persons, and the direct economic loss reached 2.398 billion yuan. Geological disasters occur on average every year 3 ... > >

question 2: what are the geological disasters in Guizhou province, such as landslides, collapses, ground subsidence, ground fissures and mudslides? Severe storm disasters, tornado, hail, snow condensation disasters, thunderstorms and thunderstorms

Question 3: How to compensate for the relocation of geological disasters in Guizhou Province in 216

According to the relevant provisions of the Regulations on the Prevention and Control of Geological Disasters (the State Council Order No.394), it is deployed according to the arrangement of the province * * *, in order to effectively do a good job in the prevention and control of geological disasters in Guizhou Province in 216.

I. prevention and control of geological disasters in 215

in 215, there were 163 geological disasters in * * *, with 27 deaths, resulting in direct economic losses of 16 million 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 dominant, causing 157 cases, 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 mainly small, with 13 cases, accounting for 79.8%; Medium-sized 26 cases, accounting for 16.%; Large and extra-large disasters accounted 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.%, 1.2%, 2.5% and 1.8% of the total disasters respectively. Fourth, the time of disasters is mainly concentrated 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; There were 51 geological disasters in August, accounting for 31.3% of the whole year. Fifth, in terms of spatial distribution, there are more geological disasters in Qiandongnan Prefecture, with 64 occurrences, accounting for 39.3% of the total number of disasters; Followed by Southwest Guizhou, 53 cases occurred, 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 215, the province invested a total of 1.6 billion yuan in special funds for the prevention and control of geological disasters, and comprehensively managed 251 hidden dangers of major 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, * * * issued 17 geological disaster risk warning information, sent nearly 1.5 million mobile phone messages, successfully predicted and avoided 29 sudden major geological disasters, avoiding 4,983 casualties and 12 million yuan of economic losses. Comprehensive rotation training was conducted for more than 1,5 township land and resources institutes and more than 2,6 township land and resources institute cadres in the province to improve the professional ability of geological disaster prevention and control. For the 12,261 hidden danger points that have been identified, the geological disaster emergency drills have been completed in full coverage. 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.

second, the forecast of geological disasters in 216

according to the occurrence and development law of geological disasters in our province in recent years, considering various factors such as frequent extreme climate, the occurrence rate of geological disasters in our province will still be high in 216, with sudden geological disasters accounting for the main proportion, mainly caused by rainfall, mainly distributed in May to September in flood season and the peak period in June to August.

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

(2) Forecast of major mines. The western part of our province has deep terrain cutting, complex landform combination characteristics, uneven soft and hard strata lithology, and frequent engineering activities, mainly coal mining, which is a high-risk area for geological disasters.

(3) forecast of major traffic arteries. The railways are mainly along Guizhou sections such as Sichuan-Guizhou, Hunan-Guizhou, Guizhou-Guangxi, Neikun, Guikun, Shuibai and Nankun. The highways are mainly national highways such as G321, G326, G21 and G32, expressways such as Guiguang, Zunchong, Shuihuang, Qingzhen, Guixin, Guanxing, Guibi, Kaima, Zhensheng and Guizun, and Guizhou sections of Shantou-Kunming and Xiamen-Chengdu expressways. As well as 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 northern and northeastern regions 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 ..... >; >

question 4: is there any possibility of other natural disasters and natural geological disasters in Guiyang? Which area in Guizhou Province or Guiyang is safer? How can I say 1 points? There is no place on the whole earth that is completely safe. In theory, the probability of an earthquake in Wenchuan a few years ago is very small, but it still happened. In other words, China's capital can be said to be the place with the highest safety factor, but on July 21, more than 1 people died because of the rainstorm. 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 loved ones.

Question 5: There is no

event classification for the super-large geological disasters in Anshun, Guizhou

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

(1) Super-large geological disasters (Grade I):

(2) Large-scale geological disasters (Grade II): more than 1 people (including 1 people) but less than 3 people died or the direct economic loss was more than 5 million yuan (including 5 million yuan) but less than 1 million yuan;

(3) Medium-sized geological disasters (Grade III): more than 3 people (including 3 people) but less than 1 people died or the direct economic loss was more than 1 million yuan (including 1 million yuan) but less than 5 million yuan;

(4) Small-scale geological disasters (Grade IV): less than 3 people died or the direct economic loss was less than 1 million yuan

Question 6: What geological disasters have occurred in Bijie, Guizhou Province? Bijie geological and geomorphological environment:
