However, China is constantly planting trees and trying to completely change the original situation of little forest and little land.
From just planting a single tree, to now a tree has been transplanted everywhere, and China's approach to desertification is becoming more and more adequate.
People who have finally gone abroad no longer think that China is all "a piece of Gobi", but that the desert is gradually being squeezed into a small corner.
So, how much is the continuous afforestation in China?
Can deserts disappear in a reasonable amount of time?
Reforestation.
Don't look at the mainland now has more than 14 million square kilometers of desert, the deserts of the mainland have existed before the mainland opened up.
What's more, the desert area on the mainland is still decreasing year by year, and this is inseparable from a series of measures taken by the mainland and afforestation actions.
Afforestation extends from the south to the northeast, the north to the northwest, the east to the southeast, and the west to the southwest.
As long as it is suitable for afforestation, it should be planted as soon as possible.
Naturally, the afforestation work on the mainland also has a time sequence, and the earliest places to start afforestation are naturally those provinces in the south that have no desert.
Then the southern provinces planted trees in their own deserts, and then the central regions began to plant trees.
Finally, there is the need for reforestation in the western provinces, where most of the land is relatively poor.
Without the support of the central and eastern provinces, it would be difficult for these western provinces to complete the reforestation work.
While the afforestation work in the central and eastern provinces and coastal areas is proceeding smoothly, provincial capitals and large and medium-sized cities have also improved their own environment.
The groundwater level in provincial capitals and large and medium-sized cities has declined, and problems such as soil erosion have also been solved by afforestation.
The mainland is not alone in improving its environment, and China has also helped other countries and regions with their reforestation efforts.
For example, in order to make its afforestation program more effective, the United Kingdom has hired Chinese professionals to guide them, and the mainland's afforestation "experience" is also welcome abroad.
The mainland has also sent personnel to Africa and South America to carry out afforestation work for countries in need.
Rational and scientific afforestation can not only improve the environment and stabilize temperature, but also increase water sources.
Deserts disappear?
As China continues to plant trees, and even staged a good show of "one tree moving around", can deserts disappear in a reasonable amount of time?
At the current rate, deserts will disappear in the future.
However, judging from the ancient "map" of the continent, the landform of the continent is not what it is now.
There were much fewer wastelands in the ancient continent than there are now, which has to remind people of the history of the continent.
In ancient times, there were more grasslands than now, which was also the result of continuous afforestation on the mainland.
If the mainland does not carry out afforestation, those grasslands now will disappear in the next few decades or hundreds of years.
Therefore, deserts can disappear in a reasonable period of time, as long as the continent continues to reforest.
However, the rate of desert disappearance is not linear, and we can only say that deserts will gradually disappear in the next few decades or hundreds of years.
However, if the continent's environment and climate deteriorate to a certain extent, deserts will expand at a very rapid rate.
Therefore, the mainland should not only attach importance to afforestation and the protection of the natural environment, but also educate people on the importance of caring for the environment.
If people don't destroy nature, the deserts of the continent will disappear in a few hundred years.
Afforestation plays an important role in improving the environment, and many people do not understand: "The continent is not very large, so why can't we plant trees all over the land?" Wouldn't that improve the environment faster?"
It is difficult to distinguish between the people, and afforestation also requires a certain amount of planning.
If a large area is planted, the root system of these trees will compete for groundwater, causing problems such as soil erosion.
Especially at higher altitudes, if a large area is planted with trees, the root system of these trees can disturb the distribution of local groundwater.
Therefore, afforestation needs to be tailor-made, and it cannot only rely on planting more trees and more afforestation, but will bring greater damage to the natural environment.
There are certain regulations on the density and types of afforestation.
The types of afforestation are divided into annual vegetation and perennial vegetation, and annual vegetation is divided into early spring vegetation, mid-spring vegetation and late spring vegetation.
These vegetation species must meet not only the climatic requirements of the area in which they are planted, but also the species of afforestation in the area in which they are located.
Therefore, afforestation needs to be guided by professionals, and the planning and types of afforestation in the mainland have been done very well.
Deserts and afforestation.
The mainland has an atmospheric circulation from east to west and rolling yellow sand, and many people think: "The deserts on the mainland are all because of the wind-blown sand, and we don't need to plant trees as soon as the wind stops."
In fact, the desert on the mainland is not purely the result of wind-blown desertification, and if God had carried out a "Gobi" plan for the mainland, the mainland would have faced sandstorms every year.
There are not many sandstorm days in the northern part of the mainland (especially in the northeast) every year, and some sandstorm days are difficult to see.
If the heavens carry out the "Gobi" plan on the mainland, the number of sandstorm days will certainly increase greatly.
However, according to the data of sandstorms on the mainland for decades, the number of sandstorm days has not increased significantly, and some have even decreased.
It can be said that the sandstorms on the mainland are not caused by the "Gobi Desert", but by factors such as atmospheric circulation and rolling yellow sand.
Afforestation in the mainland can solve problems such as sandstorms very well, which is inseparable from the "outline" of afforestation.
The earliest protection of the natural environment in the mainland was in ancient times when the mainland had the idea of "protecting nature".
At that time, the land on the mainland was still very fertile, and problems such as deserts and land loss were not so common.
Therefore, people in ancient times were not in a hurry to protect the land, and there were reports of land loss in 1861.
The issue of land erosion was mentioned in these reports and solutions were proposed to address it.
But there was no incentive for these programmes at the time, as land loss was not as widespread.
It was not until 1928 that the mainland carried out investigation and research on land erosion in the Yihai area, and implemented a "program" of afforestation in the local area.
The problem of land erosion was alleviated in the Yihai area, but the reforested vegetation disappeared along with the rolling yellow sand after the 1935 earthquake that struck the Yihai area.
This has also led to a further increase in land loss in the Yihai region, so reforestation needs to follow the pace of nature.
It is not just a matter of afforestation, but in the process of afforestation, we must respect nature, and we should not act against the trajectory of nature like the Yihai area.
epilogue
The desert area of the mainland is becoming smaller, which is also inseparable from the mainland's long-term protection of the natural environment.
Deserts can disappear in a reasonable amount of time, as long as the continent continues to be reforested.
Similarly, desert areas on the continent can disappear in a reasonable amount of time, as long as people stop destroying nature.
