There are sand and dust weather in many places, why can t the sand and dust storms be completely con

Because the area of deserts on the earth is very large, and because a large number of trees are cut down every year, the desertification of green space is becoming more and more serious, the environment should rely on the joint efforts of everyone, and the strength of one country alone cannot change the global environment, so it is still necessary for all countries in the world to unite to protect the environment and improve the environment in order to have an effect.

Dust storms generally occur in arid and semi-arid regions, and are common in the north. Because of the current indiscriminate logging, the soil erosion is serious, resulting in a bad environment.

Because sandstorms are a natural disaster phenomenon, they have existed since ancient times. I want to completely control sandstorms. It's a very difficult thing.

The main reason is that sand control has always been a worldwide problem, and this sandstorm is from overseas, so it is more difficult to resist.

Because there are still a lot of desert areas, and we have a relatively small range of trees to plant now.

I think that the sandstorm cannot be completely controlled, it is caused by the geographical environment, and it can only be prevented by planting trees.

In order to prevent smog in several large cities in northern China, a large number of deforestation in the Three North shelterbelts is the main cause of sandstorms. Headache heals, foot pain heals.

Mongolia has become overly desertified due to over-mining and overgrazing. And there is no plan and no economy to govern and let it develop. Therefore, when the wind carried the sand over the alpine shelter forest and invaded the North China Plateau in the northwest, there will be more in the future.

Recently, there have been sandstorms in various places, what is the cause of it, and how to deal with it?

Yesterday it was reported that there will be a sandstorm in the north to cool down.

This morning, the weather forecast said that it was a sandstorm coming from Mongolia. The sandstorm has hit Beijing. Yellow sandstorm on a slow day.

It is the whole city that is polluted by sandstorms, and extreme weather changes make the environmental pollution too serious. The air quality is poor, for the sake of physical health, everyone tries to go out as little as possible.

The wind is blowing, and if you don't want to go out, you can stay at home, there is nothing you can do.

This is nature. The yellow sand is also normal, and there are still snowstorms in some places in the northeast today. If it's not artificial, there's no way to improve it.

The reason why sandstorms cannot be completely improved is that the land is desertified, which is affected by factors such as geographical location and water resources. In addition to the limitations of natural conditions, the causes of land desertification include human factors such as over-reclamation of land, artificial overgrazing, indiscriminate deforestation of forest vegetation, and construction of industrial, mining, and transportation.

Sandstorms cannot be reduced but can be reduced through human actions to control sandstorms and reduce the impact on human life. In order to improve or reduce dust storms, it is necessary to minimize the area of desertification.

Afforestation can reduce the phenomenon of sandstorms, but it is also unable to prevent the formation of sandstorms, because the northern region belongs to the temperate monsoon climate, cold waves and winds are frequent, and the dust from the far northwest is carried to the air by strong winds, all the way to the east.

Harness deserts and improve the ecological environment. While doing a good job in economic construction, we should also pay attention to ecological construction. Every citizen should have a strong sense of danger and environmental protection, and should strengthen more education in this regard, so as to truly do a good job in afforestation, expand the vegetation coverage rate, open up sources and reduce expenditure, and make rational use of water resources.

The root cause of sandstorms lies in desertification. Affected by geographical location, water resources and other factors, the desert will not disappear completely, which is also a reality that human beings cannot change. In addition to the limitations of natural conditions, human factors such as land over-reclamation, artificial overgrazing, indiscriminate deforestation of forest vegetation, and industrial, mining, and transportation construction are also another cause of land desertification.

Therefore, a sandstorm is not possible.

In recent decades, the phenomenon of sandstorms in China has improved to a certain extent. But in the face of strong winds, shelterbelts cannot stop the formation of sandstorms. The root cause of sandstorms lies in desertification.

Affected by geographical location, water resources and other factors, the desert will not disappear completely, which is also a reality that human beings cannot change. In addition to the limitations of natural conditions, human factors such as land over-reclamation, artificial overgrazing, indiscriminate deforestation of forest vegetation, and industrial, mining, and transportation construction are also another cause of land desertification. Therefore, a sandstorm is not possible.

However, human beings can still control sandstorms and reduce their impact on human lives through their own actions. In order to improve or reduce dust storms, it is necessary to minimize the area of desertification.

Sandstorm defense measures.

1. Strengthen the protection of the environment and raise the protection of the environment to the level of the legal system.

2. Restore vegetation and strengthen the biological protection system to prevent wind-blown sandstorms. It is necessary to protect and restore forest and grass vegetation in accordance with the law, prevent the further expansion of land desertification, and reduce the source of sand and dust as much as possible.

3. Formulate disaster prevention, disaster resistance, and disaster relief plans according to local conditions in different regions, actively promote various disaster reduction technologies, and build a number of demonstration projects, which will be gradually promoted from point to area, and further improve the regional comprehensive defense system.

4. Control population growth, reduce the pressure of human factors on land, and protect the environment.

5. Strengthen the scientific publicity of the relationship between the occurrence and harm of sandstorms and human activities, so that people realize that once the environment they live in is damaged, it is difficult to recover, which not only aggravates sandstorms and other self-congratulatory disasters, but also forms a vicious circle, so people should consciously protect their living environment.

6. Plant plants suitable for growth in desert arid areas, such as sea buckthorn, in desert areas to form a ground cover plant layer, so as to improve the ground cover environment, fix the soil, reduce wind speed, increase air humidity, and improve the microclimate environment.

7. Plant native varieties of low shrubs and small trees at the edge of the desert to improve the distribution of vegetation.

As long as there are many trees, there is really no good way to do it.

Nowadays, a large number of deforestation in society leads to air pollution.

Countries with foreign countries.

It's like Russia.

My mom said that when they went to Russia, the cities were almost always in the forest, and the air was very good.

A large number of trees have been planted and forests have been returned to forests.

Sandstorms mostly occur in Northwest China and North China, mainly in winter and spring. Sandstorm refers to a disastrous weather phenomenon in which strong winds roll up a large amount of sand and dust from the ground, making the visibility less than 1 km, and having the characteristics of suddenness and short duration, with small probability and large harm.

In winter and spring, when the ground is dry and loose, the winds brought by the cold Siberian snap sweep the sand and dust into the air, forming a sandstorm.

There are three conditions for the formation of sandstorms. One is the sand and dust on the ground, the second is strong winds, strong winds, and the third is an unstable air state.
