Some people blame the cause of the sandstorm on the shelterbelt, but what is the truth?

Early in the morning of March 15th, various social platforms were swiped by friends in Beijing and Ningxia, and the **and** of various sandstorms shocked people, and many netizens sighed that sandstorms like this have not appeared for more than ten years. Many netizens have thought of the news in January this year, Dunhuang's shelter forest was cut down in a large area, opening a big hole, many people have doubts about the comparison, I don't know if there is a connection between the two. <>

Due to the continuous strengthening of the prevention and control of land desertification in recent years, the establishment of the three-north shelterbelt system, and the area of the shelterbelt has expanded year by year, in recent years, China's sandstorm weather has gradually decreased, and the degree has been decreasing, like today's sandstorm weather has not been seen for many years, so it is easy for everyone to think of the incident of the shelterbelt being cut down in January, and there is no clear investigation result yet, so netizens are very indignant about this. <>

In fact, the key to this incident and sandstorm weather is still small, and meteorological experts have explained this, believing that the gap event in the shelterbelt has little or even negligible impact on sandstorm weather in Beijing and other places. The cause of this dust storm is related to particularly strong cyclones and weather conditions such as recent warmer temperatures and less rainfall. The weather conditions were so bad that it was unrealistic to rely solely on the shelterbelt system.

Therefore, in fact, the sandstorm weather in Beijing and other places has little relevance to the incident of the gap in the shelterbelt, and it is more the impact of extreme bad weather, but the sandstorm has sounded the alarm.

For us individual citizens, we have to start from ourselves, many times do not pollute the environment at will, especially when opening factories, we must try to abide by the country's environmental protection laws and regulations, which is possible for us. Many of our environmental pollution is caused by improper emissions from factories, and now many factories follow this rule, so there are not so many cases of environmental pollution, and now this dust storm is obviously a reminder that we need to protect the environment. <>

In short, this incident sounded the alarm bell, telling us that although the environmental and ecological management work in recent years has achieved good results, but still can not relax, we must insist on protecting our homeland, lucid waters and lush mountains are invaluable assets, we must continue to improve the shelterbelt system, strictly prevent intentional destruction, afforestation, wind and sand fixation, and strengthen the awareness of prevention and control.

Do I think the big hole in the shelterbelt is the main reason? Because sand and dust storms will enter the shelterbelt through this opening, and disintegrate the soil of the shelterbelt from the inside, resulting in serious soil erosion.

The sandstorm is mainly in Mongolia, and the sandstorm in Mongolia moves southward with the airflow and then enters China. It is not enough for China to do a good job of shelterbelts, and global action is needed to completely control sandstorms.

It was because someone cut down the shelterbelt that led to the arrival of this sandstorm.

Because shelterbelts play a role in sand prevention and sand fixation, if they don't do a good job, then it must be their relationship.

The Three-North Shelterbelt can fix sand, but it can't block the wind or the sand and dust transported by high altitudes. There are also deserts in Central Asia such as Mongolia, which are one of the birthplaces of sandstorms. As long as there are deserts on the earth, there will be sandstorms.

Because sandstorms are a natural phenomenon that originates in desert areas. Qin Dahe, former director of the China Meteorological Administration, also said that according to the laws of nature, sandstorms cannot be completely eliminated.

There have been large-scale sandstorms in northern cities. Some workers work outside for two hours with a layer of dust on their masks. The sandstorm in northern China has been hailed as the strongest in the past decade, which has led some people to question the role of shelterbelts.

In fact, we cannot blame all the blame for the failure of shelterbelts, and the different years of planting of shelterbelts will form different tree protection effects. What's more, the unreasonable development of local residents will also affect the shelterbelt to play a protective role, the large-scale sandstorm weather in northern China depends on the wind direction, wind force and weather conditions, and the relationship between sandstorm weather and shelterbelt is more subtle, we must not attribute all the responsibility to the shelterbelt did not play its original role.

The first reason: the planting time of shelterbelts is too short

The process of everything happening is not achieved overnight, and even the occurrence of many things is the result of a long period of evolution. The process of tree growth is very slow, especially in shelterbelts planted in harsh areas and areas where water is scarce. It takes about 15 years for most shelterbelts to form protective forests, and a large number of shelterbelts will be planted every year in China, which may lead to the failure of newly planted shelterbelts to play a strong protective role, and eventually lead to sandstorms in the northern region.

The second reason: people in different regions have different lifestyles

It is clear that in some areas, shelterbelts that have begun to take shape have been permanently destroyed and deforested, and that local residents have caused widespread death of shelterbelts in favor of grapes that require more soil moisture. Although many ** have reported on this incident, they have never been able to reach a specific conclusion. Perhaps in some places, shelterbelts have been irreparably damaged, and after the shelterbelts are destroyed, there is no effective green barrier in the area, and huge sand and dust will follow.

The third reason: there is a serious gap in the planting chain of shelterbelts

Everyone is pursuing higher personal interests, and we cannot rule out that some staff members in the process of planting shelterbelts, they will transfer part of the funds into their own pockets, which will lead to a huge gap between the actual planting of shelterbelt trees and the national shelterbelt trees, and ultimately lead to large-scale shelterbelts can not play the purpose of hindering the entry of wind and sand into northern cities.

In general, the ineffectiveness of shelterbelts is closely related to the way people plant them, the scale of their planting, and the number of years they have been planted.

Because the sandstorm formed this time is very serious, the shelterbelt can only play a role in weakening it, but cannot completely stop it.

I don't think it's that the shelterbelts are not working, but that the scale and intensity of the storm are much larger than the scope of the shelterbelts.

Because of the wide range and the high height of the dust raised, the shelterbelt did not work.

Shelterbelts can only improve small sandstorms, and the impact of shelterbelts on large wind farms is very limited, especially for such strong weather, which is basically negligible.

The recent sandstorm is the most serious sandstorm in the last decade, and the power is huge, and the scope is relatively large, and the shelterbelt has limited protection capacity, and can only prevent sandstorms to a limited extent.

Beijing has been hit by the worst sandstorm in 10 years, but shelterbelts have greatly reduced sandstorms in China.

This sandstorm has nothing to do with the opening of the shelterbelt, and even some people thought that it was an opening in the shelterbelt belt, blowing away the haze, but ushering in the wind and sand. Not really! The shelterbelt is mainly a certain transformation of the ground plants near the ground, and its impact on the whole wind field is particularly limited, especially for the whole process of such particularly strong weather conditions, the impact of the shelterbelt on the wind can be basically ignored.

Therefore, shelterbelts have an impact on wind, and thus on wind-blown sand, which can be negligible.

In recent years, with the overall solid progress of China's planting and green protection, windbreak and sand fixation, the sand and dust weather has achieved obvious, reasonable and effective continuous improvement. The large-scale and high-impact wind-blown and sandy weather conditions remind everyone that the overall environment in China is still likely to sound under extremely unfavorable conditions. Therefore, in a certain aspect, it is necessary to continue to solidly promote the overall work of planting greenery and protecting greenery, windbreak and sand fixation, and green ecological environment governance; On the other hand, the Bureau of Meteorology must further strengthen data monitoring and weather forecasting to provide considerate services.

The Meteorological Bureau predicts that under the influence of cold air, there will be northerly winds with gusts and sandstorms on the 15th, and the weather conditions will continue until the afternoon, and will gradually weaken at dusk, and the wind speed will decrease at night, and the visibility will improve.

There is a large amount of inhalable particulate matter in the sand, so you should not go out as much as possible, turn on the air purifier or household fresh air system and close the windows and doors in the room, and wear a mask if you go out for a short time. Wind and sand will continue to carry pollen and pollen foods, as well as air pollutants that are harmful to the body. When you return home, you should cleanse your face and take care of your skin as soon as possible.

The number of Shijing hair is especially large, and the diameter is relatively small, which brings the total area of hair to be particularly large (especially long hair), and it is most recommended to be cautious about sucking wind and sand, so you should wash and dry your hair as soon as possible when you return home.

I don't think it's entirely to blame the shelterbelt openings, and we should also plant some vegetation in the plains, but these can only be weakened, and the sand and dust are raging, and they can't be completely stopped. I think it will become a reality, and if everyone blindly cuts down and does not protect the earth on which they live, the wasteland world will become a reality. Boom.

There is no causal relationship between the ravages of sandstorms and the tearing of shelterbelts. Shelterbelts can weaken the power of sandstorms to a certain extent, but they cannot completely stop the raging sandstorms.

No, we should reflect on our own actions, if we hadn't cut down trees indiscriminately, the shelterbelts wouldn't have opened their mouths. If I continue to cut down trees, then the wasteland world may become a reality.

The main reason for the ravages of sand and dust is the opening of the shelterbelt, because the trees have the effect of slowing down and preventing dust. The world of the Orange Wasteland will not become a reality, as long as we humans awaken from now on and protect our homeland.

This possibility is still relatively small, although there are many places where the ecological environment has been damaged very much, but it will take a certain amount of time to become a wasteland world like this, as long as we take good care of it, there will be no such situation.

No, the role of the shelterbelt is very small, it can only play a role close to the ground, but in the face of such a large scale, it has no effect at all, and the northern climate is relatively dry, there is no rainfall, so this phenomenon will happen.

There should be considerations, but the wasteland world will not be able to reach it in the near future, and it will not become a reality, because it is impossible to complete it.

No, the shelterbelt has a deep impact on the wind, which causes the sky to be full of yellow sand, and there are many green plants in our country, so there is no need to worry.

Personally, I don't think the sand and dust are raging, and the wasteland world may become a reality, if we don't protect the environment well.

The strongest dust storm in Beijing has nothing to do with the opening of the shelterbelt. Relevant experts also responded to the formation of this sandstorm, and there is no direct causal connection with the opening of the shelterbelt.

What is the origin of this dust storm?

The sandstorm in Beijing can be called the largest sandstorm in the past 10 years, and experts from China's Meteorological Bureau have also given their views and explanations on the cause of the sandstorm. They believe that there are two main reasons for the strongest dust storm.

The sand and dust storm is very powerful and has a large impact area, and it can be regarded as the largest sand and dust storm in the past decade. So what caused the sandstorm? According to experts from China's Meteorological Bureau, there are two main reasons for the formation of this sandstorm.

On the one hand, it is due to the fact that in the past period, the weather and temperature in most parts of northern China and Mongolia have been very dry, and the rainfall has been seriously low.

On the one hand, it is also due to the fact that during this period, the wind intensity in Mongolia and northwest China was relatively large, and the time lasted longer than usual, which provided acquired conditions for the formation and spread of sandstorms.

What lessons does the strongest sandstorm in Beijing bring us?

Although in order to protect the environment, China has also invested a lot in sand prevention and control in recent years, and the results achieved are obvious to all, and the occurrence of sand and dust storms is much less than before, but this time there has been the strongest sand and dust storm in 10 years, which has also sounded the alarm for us.

First of all, the work we have done in the past to prevent and fix sand still needs to strengthen and continue to protect the environment, which is still very important.

Secondly, it also tells us that environmental problems are no longer the responsibility of any one country, and the impact of environmental problems will not be limited to one country. More countries need to join hands and work together to protect the environment.

What can we do to prevent sandstorms?

This sandstorm reminds us that there can still be sandstorms under certain conditions or in extreme weather. The fight against sand and dust storms still needs to continue.

First of all, it is necessary to do a good job in the source management of sand prevention and fixation. Only by investing from the source and eliminating the conditions for the formation of sand and dust can we fundamentally prevent the occurrence of sand and dust storms. Therefore, for the coverage of forests, farmland and grasslands, it is still necessary to strengthen and continuously improve the green plant coverage rate of the soil, maintain and ensure the moisture of the soil, and reduce unnecessary exposure of the soil, which is an innate condition to eliminate the formation of sand and dust at the source.

Second, it is necessary to do a good job in international cooperation on environmental protection. This extreme sandstorm once again shows us that if we want to protect the environment, we still need to work together with each other.
