Why did the Mu Us Desert suddenly disappear in history, and how many deserts have disappeared in my

There are about seven or eight deserts that have disappeared, and the deserts have disappeared because of tectonic plate shifts or sudden rainstorms.

There should be more than 500 of them, in fact, because we protected the ecological environment and then planted some civil engineering.

During the Sui and Tang dynasties, the development of agriculture further expanded the area of Mu Us area, and due to factors such as population growth and climate change, small areas of sandy land began to appear in the area. In the following 1,000 years, the area of sandy land continued to expand, and by the Ming and Qing dynasties, it was already a vast desert. A lot of desert has disappeared.

Located between the Yulin region of Shaanxi Province and the city of Ordos in the Inner Mongolia Autonomous Region, the Mu Us Desert is one of the four major sandy areas in China.

According to research, in ancient times, this area was rich in water and grass, and the scenery was pleasant, and it was a good pasture. Later, due to climate change and war, the ground vegetation was completely lost, and sand was raised on the spot, forming the later desert (sandy land). There was a story of "three relocations of Yulin" here.

Now it is not what it used to be, and now Yulin is a "famous city".

In the 60s of the 20th century, there was no grass growing quicksand half a kilometer away from the suburbs of Yulin City, and at the beginning of the 21st century, there was basically no quicksand within 50 kilometers. Much of what was once sandy land is now woodland, meadow and fertile land. In the hinterland of the desert, Yulin City has also accumulated 1.6 million mu of new farmland.

By the beginning of the 21st century, more than 6 million acres of sandy land had been remediated, and the sand was stopped and greened. Eighty percent of the Mu Us Desert has been brought under control, soil and water have been lost, and the annual sediment transport of the Yellow River has been reduced by 400 million tons. Thanks to good precipitation, many sandy areas are now woodlands, meadows and fertile fields.

In the hinterland of the desert, Yulin City has also accumulated 1.6 million acres of new farmland, and Yulin, the "desert capital", has become a "desert oasis".

Mu Us Desert.

It will disappear because it is about to become an oasis. The Mu Us Desert is located in Yulin, Shaanxi.

The area of the desert is about square kilometers.

According to research, the area of the Mu Us Desert is not so large as it should be, and it was also rich in water and grass in ancient times. However, with the irrational human behavior such as grazing and reclamation, as well as climate change, the ground vegetation in the Mu Us Desert has begun to decline day by day. Over time, the desert area of Mu Us began to expand.

By the time of the Ming and Qing dynasties, it had become a vast desert. <>

After entering the period of New China, people began to establish windbreak belts in order to prevent the further expansion of the Mu Us Desert. In addition, people have also taken measures to control the Mu Us Desert such as water diversion and sand diversion, flood diversion and siltation. In fact, in terms of the climatic conditions of the Mu Us Desert, the amount of precipitation in this area.

In fact, it is relatively rich. Annual precipitation can usually reach more than 250 mm, with July to September being around 60%-75% of the annual precipitation. Based on this precipitation, it is relatively easy to establish a windbreak in the Mu Us Desert.

People's prevention and control of the Mu Us Desert began in the fifties of the last century, and the people involved in the prevention and control were both "officials" and "people". Among them, as far as the "official" is concerned, because the Mu Us Desert exists in the jurisdiction of Shaanxi, Ningxia and Inner Mongolia provinces at the same time, its prevention and control work is jointly carried out by the three provinces. These three provinces** plan separately according to the desert land conditions within their jurisdictions.

As far as the "people" are concerned, many enterprises and individuals have been very actively involved in the management of the Mu Us Desert. <>

With the joint efforts of the "officials" and the "people," the prevention and control work of the Mu Us Desert has achieved very remarkable results. As of the beginning of the 21st century, the Mu Us Desert can be said to have taken on a new look after nearly half a century of prevention and control, and more than 600 acres of sandy land have been treated. The yellow sand in these sandy areas has been replaced by lush trees, and Yulin, which had been at the forefront of wind and sand encroachment, has become a "plugged oasis".

Last year, the Shaanxi Forestry Bureau also indicated that the area of sandy land to be treated had been reached.

If this trend continues, it is estimated that the Mu Us Desert will soon be completely replaced by oases. If that day does come, the name of the Mu Us Desert will become unworthy of its name. In this case, the disappearance of the Mu Us Desert from the map of Shaanxi is a sure thing.

Because the desert has changed a lot over the years, it is no longer a barren land, so it will disappear from the map.

Because this place is very well greened, now the desert area is getting smaller and smaller, and many places are covered by thick shade, so this desert land is about to disappear.

This is due to large-scale afforestation activities and large-scale greenery in the area, which has turned the local desert into an oasis.

Introduction: With the gradual improvement of China's ecological laws, some sandy lands in China have gradually become oases, which is something that every Chinese is proud of, China is working tirelessly every day for the dream of turning the desert into an oasis, and China also has many successful cases, such as the Mu Us Desert has successfully become an oasis, after which many netizens ask why the Mu Us Desert is about to disappear? However, the Taklamakan Desert cannot be eradicated yet, so today I will take you to understand the reasons for this.

1. Mu Us Desert.

Mu Us Sandy Land is a relatively large sandy land in China, once Mu Us did not see a green tree and grass at all, but with the unremitting efforts of people, Mao Su finally disappeared in the eyes of people, and ushered in a very huge green ecological environment, this is the result of China's sand management policy, Mao Su Sandy Land has become an oasis, but also reflects the best intentions and the superiority of the management method. <>

2. The Taklamakan Desert.

The fundamental reason why the Taklamakan Desert cannot be transformed from sand to green forest is actually very simple, because the Taklamakan Desert and the Mu Us Desert, the two of them have a fundamental difference, the Mu Us Desert is not actually a desert, but a piece of sand, the Mu Us Desert, in fact, was a pastoral area before, but due to people's overgrazing and some reasons, the soil here was reduced to form a sandy land. The Taklamakan Desert is a real desert, so it will be very difficult to manage. <>

Third, it is difficult to govern.

If you also change the Taklamakan Desert by planting trees, it is likely to make the local area more arid, because the Taklamakan Desert is not like the Mu Us Desert, the Taklamakan Desert is formed by natural factors, it is very far from the ocean, so the evaporation is very serious, if you add some plants, the transpiration of these plants is more likely to make the groundwater less and less, therefore, the Taklamakan Desert is difficult to turn into an oasis.

Because of the different geographical location, the conditions under which it was formed were different from those of the desert, and the main reason was the climate, which did not change.

Because it is located in a relatively good geographical location, it will not disappear easily.

Because the environment of this desert is so harsh, and there is not a single tree in it, this desert will not disappear.

The Mu Us Desert in northern Shaanxi will disappear, and if the desert disappears, will it destroy the ecological balance?

1. What is going on with the disappearance of the Mu Us Desert in northern Shaanxi? Mu Us Desert is a relatively large desert area in our country, before this place is always full of yellow sand, the surrounding people are suffering from desertification, in order to control the Mu Us Desert local people and researchers after decades of exploration and efforts, finally turned the Mu Us Desert into an oasis, now about 80% of the Mu Us Desert is planted with vegetation, soil erosion and desertification has been effectively improved, it is estimated that it will not be long after, The Mu Us Desert will disappear from the stage of history and completely disappear into this place, and the locals will no longer have to live a life full of yellow sand.

2. If the desert disappears, will it destroy the ecological balance? For the Mu Us Desert that is about to disappear, many people are very happy in their hearts, which means that China's achievements in desert governance have become more, but some people will question whether the disappearance of the Mu Us Desert will cause some damage to the ecosystem, because many plants or animals living in the desert may become homeless because of the disappearance of the Mu Us Desert, and the entire ecological balance will naturally be destroyed. But the desert is also formed in the process of long-term historical evolution, many times the desert is caused by climate change, so coupled with the influence of human activities, slowly the desert appeared on the earth, and the animals and plants that can survive in the desert are actually very rare. However, the disappearance of the desert will indeed make these animals and plants living in the desert homeless, and the ecosystem will be more or less affected, but what kind of impact will it bring, there is no way to make a judgment now, however, the life of the local people, because the governance of the Mu Us Desert has become better, but it is a real thing, so the governance of the desert is imperative, and whether it will cause damage to the ecological balance also needs further research to be determined.

3. What efforts have been made by the local people to clean up the desert? In order to be able to manage the life of the Mu Us Desert, the people in this land year after year, day after day through artificial planting and windbreak and sand fixation work, the desert has become an oasis, in this process, in order to find a reasonable way to control the sand, after many years of attempts, summarization and research, only to use a local grass to make a square, only to manage the desert that is constantly moving forward, the local people not only endure the wind and sun for the sand control work, They also insist on the work of wind prevention and sand fixation under the extreme shortage of water, so their efforts should be seen, and I hope that under their work, the Mu Us Desert will really disappear in this world, and I hope that their efforts will be rewarded in the end.

It will affect the ecological balance. And this situation is also very bad, and I hope we can pay attention to it.

If the desert disappears, it will definitely destroy the ecological balance, because some plants are still more suitable for desert growth, which will cause sediment loss and there is no way to consolidate the soil.

It's going to be ruined, so let's not let that happen, we should get a very good living environment.

Absolutely. If this happens, it will cause great damage to the ecological balance. It can also trigger a series of natural disasters. So be sure not to let that happen.

Yes. Because deserts are an important part of the ecological environment, and they are large and have a deep impact, they will damage the ecological environment.

The Mu Us Desert is located in the north of the first line of the Great Wall in Yulin, Shaanxi Province, covering an area of about 10,000 square kilometers. The average annual temperature is about 6 degrees, and the causes of the desert are the lack of precipitation and the loose soil, which is dominated by coarse sand. The third is artificial destruction.

Insufficient precipitation is the decisive factor. If it is properly managed according to the actual situation, the Mu Us Desert will not completely turn into a grassland or forest, but the area of the desert will gradually shrink. If deserts become oases in large numbers, then the oxygen content in the air will increase significantly, carbon dioxide will decrease, greenhouse gases will decrease, the earth will soon cool down, and the greenhouse effect will be alleviated!

Whether it is from the earth's ecological system, or from the earth's biological chain circulation system, the existence of desert geology is the most meaningless, the three most basic ecology on the earth, can basically be classified as precipitation, oxygen, food, and none of these three ecology can be produced or affected by deserts. The rainfall on the earth is more affected by the ocean and sunlight, oxygen is more produced by plant photosynthesis, and food is not produced in the desert, let alone mass production, and even basic survival cannot be guaranteed, so the existence of the desert does not contribute to the ecology.

Of course, there are many people who say that the existence of deserts has the effect of increasing precipitation, because wind-blown sand will roll up a large number of fine sand particles, and at the same time as forming sandstorms, sand particles will also increase the weight of water droplets when rainfall is formed, similar to artificial rainfall. However, this is based on the hazards of sandstorms, and is not a necessary condition for rainfall, it is only a chicken rib effect, and sandstorms themselves also affect the ecology. In fact, from the attitude of the whole world towards the desert, it can also be seen that the existence of the desert is of little significance, only to control the desert, and never increase the active behavior of the desert.

If the world's deserts disappear, it will be nothing more than the disappearance of some animals and plants endemic to the desert, and it will not have an impact on the essential ecological cycle. It's just that existence is reasonable, and we only measure the significance of the desert from the perspective of human beings, which is biased in the universe.

The Mu Us Desert is about to disappear, which will have an impact on the natural ecology, but in general, the benefits outweigh the disadvantages, so don't worry, but there will be some impacts on the ecological environment that will not be damaged.
