Disaster Prevention and Mitigation, Scientific Development Geography Operation

In the face of frequent natural disasters, it is certainly not enough to take superficial measures, but should be fundamentally addressed. Generally speaking, there are several major natural disasters. Now, we can't be exact, but we do know why and the approximate location where it's more likely to happen.

Living in the ** belt and buildings, you have to be at that level. Or reduce life in the ** district. Therefore, it is necessary to conform to the laws of nature and maintain the ecological environment, which is the best way to deal with natural disasters.

Our country is a vast country, and the weather can change greatly. Irresistible disasters such as floods, hurricanes, tornadoes, and ** occur frequently. Wenchuan has caused great damage to people's lives and property.

Over the past 50 years, the direct economic losses caused by natural disasters such as geology, droughts and floods, oceans, and epidemics have accounted for about 4% of China's GDP every year. Natural disasters have become an important factor affecting China's economic development and social security. Relying on scientific and technological progress to improve China's comprehensive disaster prevention and mitigation capability has become a top priority.

First of all, it is necessary to use scientific and technological methods and means to find out the causes of disasters and establish more effective monitoring methods. Most natural disasters have specific causes and mechanisms, and understanding the influencing factors behind disasters and their interrelationships is the basis for disaster prevention and mitigation. For example, droughts and floods are associated with anomalous currents in the Pacific Ocean and flood seasons in astronomical tides, while they are caused by tectonic plate movements, volcanic activity, and geological collapses.

Second, we should apply advanced technology to observe the Earth around the clock and detect the precursors of disasters. Disasters are an important driving force for the progress of human technology, and the ability of human beings to achieve disasters is constantly improving.

Third, it is necessary to reduce disasters in a scientific manner and not fight a war for which we are unprepared. Science can help with disasters and can also help reduce the extent of the damage caused by disasters. Nowadays, with the development of science and technology, human beings have become more and more capable of transforming natural landforms and resisting disasters.

Humanity can also improve the resilience of infrastructure in disaster-prone areas by raising safety standards and introducing more advanced technologies. <>

Through publicity, the public can fully understand the important role of disaster early warning information, understand the meaning of various types of early warning information, and take active and effective response measures according to different early warning information and different warning levels when receiving disaster early warning information. At the same time, it is necessary to establish extensive and unimpeded channels for the release of early warning information. Early warning information can be released through broadcasting, **, SMS, block display, Internet, etc., and important early warning information can be inserted in real time and rolled out in TV programs.

Relevant departments should ensure that the public receives disaster warning information in the shortest possible time, so that they have time to take corresponding defensive measures to achieve the purpose of reducing personnel and property losses.

We can't be exact, but we do know why and where it's more likely to happen. People who live in belts and buildings must be at that level. Or reduce the life of the ** area.

Therefore, the best way to deal with natural disasters is to follow the laws of nature and maintain the ecological environment.

You must do a good job of self-protection, and you must be calm and calm, don't panic, no matter what happens, you must put your own life first, and you must protect your own safety.

We should first do a good job in earthquake prevention and disaster reduction, know how to deal with safety when we know the county, know the causes of natural disasters, and then solve them and do our own work.

In the face of natural disasters, we should pay attention to safety when traveling, do not go to low-lying and landslide-prone places, and try not to go out when it rains.

In the face of natural disasters, we should adopt the right way, make correct judgments, and use scientific methods to deal with them.

The application of geographic information technology in disaster prevention and mitigation is as follows:

1 Remote sensing technology.

1) Concept: It is a geographic information technology that uses optical or electronic equipment installed in aircraft or spacecraft to perceive surface objects from a distance.

2) Advantages: It has the advantages of large detection range, fast information acquisition speed, short period, large amount of information, and less restriction by ground conditions, and can realize real-time and dynamic monitoring of ground object information.

3) Application. It can monitor the formation process of floods, typhoons and other disasters in real time, and carry out accurate forecasts and early warnings.

It can quickly identify the scope of impact of sudden natural disasters, and provide strong support for disaster statistics, disaster relief and other work.

2 Global Navigation Satellite System.

1) Composition. Space part: satellite constellation.

Ground control part: ground monitoring system.

User part: signal reception system.

2) Characteristics: It has the characteristics of global, all-weather, continuous and real-time.

3) The world's major satellite navigation systems: the global positioning system of the United States, the global satellite navigation system of Russia, the Galileo satellite navigation system of Europe, and the Beidou satellite navigation system of China.

4) Application: Using the signal receiving equipment installed in mobile phones, cars, airplanes, ships, etc., it can be accurately positioned to help users send out distress signals when encountering natural disasters or facing disaster risks.

3 Geographic Information System.

1) Concept: It is a computer information system that inputs, processes, stores, manages, queries, analyzes, and outputs geographic data.

2) Application: Using the geographic data provided by remote sensing technology and global satellite navigation system, the dynamic monitoring, forecasting and early warning of natural disasters can be carried out, and the scope and situation of disasters can be quickly determined, so as to provide a basis for formulating disaster reduction plans, assessing disaster losses and guiding post-disaster recovery and reconstruction.

First of all, we need to have an in-depth understanding of various disasters, and conduct many drills to familiarize ourselves with the first aid measures taken in case of disasters. When disaster struck, people of all ethnic groups across the country worked together to overcome difficulties.

When the typhoon comes, pay attention to the typhoon warning information in time, try not to go out indoors and close the doors and windows, stick tape on the window glass into a rice shape outdoors, do not take shelter near the billboard trees of temporary buildings, and if you are driving, you should immediately drive the car to the underground parking lot or hidden place. If you hear a thunderous roar from a distant valley in the mountains, or see the Pythagorean stream cut off or suddenly, it may be a sign of a debris flow, and immediately evacuate to the slopes on both sides that are perpendicular to the debris flow, and do not walk along the downstream direction of the debris flow ditch. When English comes, try to unplug household appliances indoors, avoid calling mobile phones or wires**, pay attention to avoid isolated high-rise buildings, telephone poles, large trees, billboards and other dangerous objects, and try to avoid buildings equipped with lightning rods and other safe places.

I think that if we want to deal with these natural disasters more scientifically, we need to strengthen our awareness and solutions in our daily lives, and solve them through more scientific means.

I'll run to a high place when it happens, I'll run to a high place if there's a flood, and I'll run to a high place when I meet you.

First of all, before facing natural disasters, we must have enough awareness and ability to resist disasters and avoid dangers in education, and we must also have enough scientific self-protection ability in the event of disasters.

<>We all know that the other day was the 13th anniversary of Wenchuan**, and when it comes to Wenchuan**, I think it should have left a deep impression on many people. In 2008, when I was still a primary school student, the only thing I felt in the face of this major disaster was that the whole country was united. Because at that stage, the chaos of Wenchuan became a ruin because of **, which caused many deaths.

What we must do every day is to stay in front of the TV to watch the first news broadcast every day, many moving stories also appear in these reports, in that difficult and difficult period, not only the national leaders personally went to the disaster area to condole, and many people are calling on everyone to donate to the disaster area, many people risked their lives to go to the disaster area as volunteers, at that time China was really the whole country. China's speed and the "support from all sides" have shocked the world.

Even though so many years have passed in Wenchuan**, the people of our country dare not forget this disaster again. Don't forget to learn from your lesson at all times. When this disaster came, all primary and secondary schools across the country held ** drills, and this behavior has continued to this day.

Then many netizens asked: How should we respond scientifically in the face of disasters?

I'm sure you should know all about what to do when it happens, after all, we've simulated it many times. When we encounter **, first of all, don't panic, we must maintain a certain calm. In this way, we can make the right behavior, ** when the time comes, we must run to the open area, do not go to the elevator, take the ladder.

When you really find that you can't escape the floor, look for hard objects or hide under the triangular foundation, protect your head and wait for rescue, believe that our country will not abandon us, never give up your life, keep hope in life, and maintain your physical strength, this is the most correct thing to do.

Of course, I hope that everyone can seriously learn the rules of the drill when the disaster comes, so that we can avoid losses to the greatest extent when the disaster comes.

In the face of disasters, the first thing to pick up is to ensure their own safety, and the others can be put down first, for the early mudslide, you must flee to a high place and run in the direction of the water.

I think that if we want to better deal with disasters scientifically, we need to master the awareness of self-protection and prevention in our daily life, and we must keep quiet in the face of disasters and think of solutions.

In front of the child, first of all, calm down, don't panic, if you can solve it yourself, you can implement some effective measures, or call ** to help.

Dear, if the short block fruit is helpful to you, you can give me a thumbs up, if you still have questions, you can continue to ask me questions, I wish you a happy life! Thank you

Hello dear I am happy to answer for you, and I will answer your question as follows:1Promoting reconstruction and development:

In the aftermath of a natural disaster, the affected areas need to be rebuilt and rehabilitated, which may boost the local economy. For example, the reconstruction of infrastructure such as roads, bridges, and buildings may create a large number of jobs and boost local economic growth. 2.

Improving the environment: Certain natural disasters may improve the local environmental situation. For example, flooding may wash away garbage and pollutants and reduce the level of pollution in water bodies; Volcanic eruptions may bring new nutrients to the soil and promote plant growth; **May change the terrain, form new ecosystems, etc.

It is important to note that although natural disasters may bring some opportunities, their damage to human beings and the natural environment is very serious, and we should take active measures to reduce their impact on human society and ecosystems.
