Sandstorm news swipes the screen, why can t sandstorms be completely controlled?

The reason why there is no way to completely control sandstorms is because the current environmental pollution situation is very serious, and for the whole earth now, the greening is very little, and even now there are a large number of people cutting down indiscriminately, especially when encountering some forest fires, which is a direct threat and harm to the life of our earth. Therefore, for many of us today, afforestation has always been the top priority that we have been emphasizing, and the reason why we have not been able to completely control sandstorms. It is because we have not done enough comprehensive and thorough greening for greening.

Because we all know that this earth may have more water, but with the greenhouse effect, the evaporation of water vapor has caused very serious harm to our direct environment, and coupled with our human beings do not pay attention to protecting the environment, resulting in the harm of our entire earth is getting higher and higher, so there will be all kinds of bad weather, and sandstorms will follow.

Many of us can find that in the first two days in the northern region, especially in Beijing, Inner Mongolia, Shanxi, Hebei and other regions, we have been harmed by the bad castle, especially for some industrial and mining areas in Inner Mongolia, sandstorms have greatly affected many of our people. Throughout the day, starting in the morning, the sandstorm weather began to turn the weather into a yellow and clear patch, and seriously affected our daily air quality, such an environment has been seriously threatened to the safety of our human lives. <>

Dust storms are also very dangerous for many of us, especially for us now, and we need to be extra careful. Therefore, the reason why sandstorms have not been fundamentally dealt with is because we humans have been polluting the environment, and we have been indiscriminately cutting down and deforesting, and some greening is not in place at all, resulting in many of us really encountering such weather, and only then begin to regret it. <>

In fact, 2021 and 2020 have been relatively difficult, the first is because the outbreak of the epidemic has made many of us unable to live a normal life, and the second is because of all kinds of bad impacts on our weather, especially the heavy rain caused before, and even **, all kinds of bad weather have brought us a very big risk, so that many of us human beings began to worry about their future, no matter what, we must start from ourselves, everyone is responsible for protecting the environment, Everyone has a responsibility to do a good job in greening, and it is everyone's responsibility to protect the earth we live on.

Because the treatment is not thorough enough, the sand area is very vast, and the labor cost is too high. And the source of sand is not only in China.

Because the area of the desert is too large and the scope is also very wide, it is not easy to completely control the desert.

The control of sandstorms is a worldwide problem, sandstorms are not only related to sand but also related to wind, and it is easy to control sand and not easy to control wind.

It is because of the situation of sandstorms, which are affected by many things, and it is not a simple aspect that can be solved.

Because this is an environmental problem, in the case of complex natural conditions that are difficult to explore, of course, it is impossible to think of a way to deal with it.

This requires the joint efforts of many countries, not one of us to do a good job of greenery, only by working together, our ecology will be better.

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.

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.

Strong wind is the driving force of sandstorms, and the sources of sand and dust are the material basis of sandstorms, and the unstable thermal conditions are conducive to the increase of wind and the development of strong convection, so as to entrain more sand and dust and roll higher. In addition, the drought and lack of rain in the early stage, the warming weather and the rising temperature are the special weather background formed by sandstorms. Ground cold fronts and pre-convective cells develop into clouds or squall lines which are small and medium-scale systems that are conducive to the development and strengthening of dust storms. The topographic conditions that are conducive to the increase of wind speed, i.e., the narrow tube action, are one of the favorable conditions for the formation of sandstorms.

Sand-dust storm is a general term for sand storm and dust storm, which is a sign of desertification. It refers to a disastrous weather phenomenon in which strong winds roll up a large amount of sand and dust from the ground, making the horizontal visibility less than 1 km, and having the characteristics of suddenness and short duration. Among them, sandstorm refers to the sandstorm formed by strong winds blowing a large number of sand particles into the near strata; A dust storm is a storm formed by high winds that sweep large amounts of dust and other fine particles into the air.

Sandstorm weather mainly occurs in winter and spring, which is due to the semi-arid and arid areas in winter and spring precipitation is very little, the surface is extremely dry and loose, and the wind erosion resistance is very weak.
