China s desert is about to become an oasis, but a group of scourges have come, what are the scour

It is some foreign tourists who do not know how to take care of the environment, they have caused damage to this place, destroyed their ecological balance, and littered things at will, resulting in the deterioration of the environment here.

Animal. These animals harm the desert environment and eat the plants here.

This "scourge" can be said to be tourists from other places. When they arrived in the desert, they did not care about the fruits of the work of the management staff, and the garbage was littered almost everywhere, and the artificial lake built to maintain the circulation of the local ecosystem has now become a stinking ditch due to random littering. I don't cherish this hard-won green environment at all.

China has turned the Mu Us Desert into an oasis.

Among the many ecological and environmental problems faced by human beings, land desertification is the most serious one. In recent years, due to the continuous intensification of human activities, the degree of desertification and the problems caused by it are also intensifying, and the prevention and control of land desertification is urgent.

China is the country with the most remarkable results in the world in controlling desertified land, which has not only successfully curbed the expansion of desertified land, but also caused the desertified land area to continue to shrink at a rate of 1,980 square kilometers per year. After generations of hard work, China's first desert on the verge of disappearing – the Mu Us Desert – is now 80% covered in green.

Geographical location:

The Mu Us Desert is one of the four major sandy areas in China, located between the Yulin region of Shaanxi Province and the city of Ordos in the Inner Mongolia Autonomous Region, covering an area of 10,000 square kilometers. It is located at 37°N latitude and 107°20-111°30 east longitude.

It includes the southern part of Ordos in the Inner Mongolia Autonomous Region, the northern wind-blown sand area in Yulin City, Shaanxi Province, and the northeastern part of Yanchi County in the Ningxia Hui Autonomous Region. There is more precipitation, which is conducive to the growth of plants, and it is a relatively developed area of animal husbandry, and the area of fixed and semi-fixed sand dunes is larger. The Great Wall runs from east to west through the southern edge of the desert.

Mu Us Desert.

"Mu Usu" means "bad water" in the Mongolian language, that is, the place where the plant does not grow. Our country has been managing this desert since 1959, and after 60 years of governance, the once barren land of the Mu Us Desert has become a green kingdom.

The Mu Us Desert is located in the north of the first line of the Great Wall of Yulin, Shaanxi Province, so Yulin City is also known as the Camel City, which means the city of the desert, and the Mu Us Desert covers an area of about 10,000 square kilometers. Yulin City, which is located on the front line of desertification prevention and control, has continued to carry out large-scale desertification control and afforestation campaigns for more than 60 years, increasing the city's forest preservation area and forest coverage rate from 600,000 mu at the beginning of the founding of the People's Republic of China and 21.57 million mu and 33% at present, respectively. Turning a desert into an oasis may sound like a fantasy, but the celery attack on NASA (NASA) data shows:

Over the past 20 years, the Earth has been turning greener. China alone has accounted for at least 25% of the total global vegetation increase over the past 17 years.

In the middle of this vast desert lies a huge oasis with seven lakes of all sizes scattered around it, forming a rare beautiful and bizarre landscape: bounded by a road, on one side is an endless desert, where not a single inch of grass grows, making people despair;

On one side, the water is rippling, the grass and trees are verdant, and it is a scene full of life. The completely different natural landscapes are perfectly blended here, and they complement each other, which is truly breathtaking.

It took only 13 years for the people of this desert to turn him into an oasisLet's get to know this desert together. This desert is called Tianmo, located in Longbao Mountain, southwest of Xiaonan Xinbao Town, Huailai County, and is a small desert.

The desert has turned vegetable fields into waste, and it cannot be said that it is the worst, but it should be said that it is the luckiestIf you want to talk about the most industrious country in the world, it must be China. No other nation has ever been as industrious as the Chinese. There has never been a country that can compare growing vegetables with China.

Where there are Chinese, there must be vegetable gardensWhether it is a mother who has crossed the ocean to study in Europe and the United States, or a volunteer frontline, the team that went to Africa to help Africa has carried forward the tradition of Chinese vegetable cultivation without exception, and the world cannot stop the enthusiasm of Chinese people to grow vegetables, full of enthusiasm and wisdom.

The desert was a very remote place in previous timesAnd everyone knows that when you arrive in the desert, there is no sand as far as the eye can see, no water source, no flowers and trees. It's a barren place, and I don't know if I can get out of it when I go in.

In the past, many people avoided desertsNot only China is working hard to control the desert, but it is a very long and arduous task to control such a large area of desert.

In a few decades, don't try to wipe out a desertThis project is undoubtedly very hard, and the requirements for people's willpower are also very high, planting trees and vegetables in the desert to turn waste into treasure is a good way to govern the desert into an oasis.

Say it is"The worst desert"Just teasing, in fact, thinking how amazing and worth learning about human beings turning deserts into oases.

In particular, a large number of efforts have been made to turn a desert into an oasis, mainly because of its geographical location.

Because this place is very close to Beijing, it has received a lot of attention and attention, and eventually it has become an oasis.

It should be a matter of local geography, not all deserts are stubborn.

Different from the geographical environment of other deserts, Tianmu is close to the capital, so it has been vigorously rectified.

The geographical location is one reason, the proximity to the capital Beijing. Second, China has carried out long-term actions against desertification, and now not only near Beijing, but also in Xinjiang and other places, the desert green area is slowly increasing.

Deserts can lead to air problems in surrounding cities, causing frequent diseases, and only then can they be vigorously remediated.

Because it is relatively close to Beijing and has a certain influence on Beijing, the relevant departments have taken care of it.

If a large area of desert becomes an oasis, the global climate will change dramatically and the existing ecosystem will be destroyed. Deserts become oases, oxygen levels in the air increase, carbon dioxide decreases, the earth drops to low temperatures, and animals change dramatically, causing animal extinction and endangering human survival.

A desert, also known as a sand curtain, mainly refers to a barren area where the ground is completely covered with sand, plants are very scarce, rain is scarce, and the air is dry.

One-third of the earth's land is desert, and there is very little water in the desert, so people generally think that the desert is desolate and lifeless, so it is called "barren sand".

With an area of 320,000 square kilometers, the Taklamakan Desert is the largest desert in China and one of the world's most famous deserts.

Desert into Oasis Desert is also known as sand curtain, which mainly refers to a desolate area where the ground is completely covered with sand, plants are very scarce, rain is scarce, and the air is dry.

One-third of the earth's land is desert, and there is very little desert water, and most people think that the desert is barren and lifeless, so it is called barren sand. Among the eight famous deserts in China, the Taklamakan Desert covers an area of 320,000 square kilometers, making it the largest desert in China and one of the world's most famous deserts.

1. The oasis in the desert is a lake that has been accumulated for a long time and the snow melted by the ice and snow on the high mountains, plus the rain from other places, and other water sources converge on the ground to form a certain area. Then the green around the lake slowly appears, forming an oasis.

2. Of course, the oasis in the desert does not exist for a long time, and the noisy water supply in the desert will also show a certain seasonality, often in summer, the area of the oasis in the desert will be larger, and the area of the oasis in the desert in winter will often shrink.

There is definitely a change, and that is for the better!

Turning a desert into an oasis is theoretically without drawbacks. If water conditions allow, an additional oasis will only enrich the ecosystem, which can increase air humidity and conserve water in the local microclimate.

In recent years, China's desertification control has achieved significant results: it is difficult to find sand in the Horqin Desert as an "oasis", and the Mu Us Desert has "disappeared" from the map and turned into a green sea ......All these cases have brought economic and ecological benefits to local residents. But will there be drawbacks to the retreat of the sand and the green advance?

1. Will it change the biological chain of local species? For example, the ship of the desert, the camel, will the loss of the desert habitat lead to the migration or even extinction of the camel?

Another example is the cactus, as the climate becomes wetter and the living environment improves, will the cactus disappear or become a local problem?

Second, will it change the entire climate environment? News about successful desertification control will mention improving the local climate, but will it have a bad effect on the wider climate?

As we all know, precipitation in China's mainland mainly depends on the transport of ocean water vapor, and the transport of ocean water vapor depends on air flow, that is, wind. As large areas of desert disappear and are replaced by green plants, the diurnal temperature difference in the original desert area decreases, the temperature difference between the inland and coastal areas decreases, and the air pressure difference between the inland and coastal areas decreases, which will reduce the air volume and wind strength. In other words, the reduction of the rate of water vapor transport from the ocean to the inland will lead to a decrease in precipitation not only inland, but also coastal precipitation.

In turn, it will affect China's climate, the entire ecological environment, and even the economic structure.

3. Will it affect the changes in water ecology, especially in the Yellow River Basin? The Yellow River is yellow because of sand, and many places are formed by the Yellow River, such as the mouth of the Yellow River. The Yellow River Delta is formed by the siltation of a large amount of sand and soil carried by the Yellow River, which is a famous wetland in China, a necessary place for many migratory birds to migrate, and a habitat for many species.

With the successful control of desertification in the upper and middle reaches of the Yellow River, soil and water conservation has improved, the amount of sediment entering the river has decreased, the sediment transported by the Yellow River has decreased, and the growth rate of the Yellow River Delta has slowed down. However, the erosive force of seawater has not changed, and will the Yellow River Delta shrink year by year in the future, which will affect the entire wetland ecosystem, leading to changes in migratory bird migration routes and increased soil salinization?

Desert control and desertification control are good policies that benefit the country and the people, and should be vigorously supported. Should there be a degree of blind desertification and desert control? Which deserts need to be managed, which deserts need to be turned green, and even which deserts need to be protected, at least leave a home for those creatures that are supposed to live in the desert in the first place!
