Can the desert be destroyed by humans? In fact, over the years, through our efforts, some desert areas have indeed been eliminated. Of course, in the process of eliminating these deserts, some advanced technologies will make our work twice the result with half the effort. For example, in December 2016, Chinese scientists developed a "multi-function three-dimensional sand fixing truck", an environmental governance and vegetation restoration machine mainly targeting desert areas, Gobi Desert areas, and desert areas, which can swallow 40 acres of desert in a day.
How big is the desert in China?
Everyone knows that China has a very large land area, but many friends may not know how large the desert area of our China is, and they may not be very clear about what China's famous deserts are.
From a global perspective, the desert area of our China is actually very large. my country is one of the countries with relatively large desert area and wide distribution in the world. The main deserts include Taklamakan Desert , Badain Jilin Desert , Tengger Desert , Gurbantonggut Desert , Mu Us Desert, etc. Speaking of this, many friends may have some impressions. The Mu Us Desert is about to "disappear" from the Shaanxi territory. The reason for "eliminating" this desert is that our country has carried out a huge project to transform the desert. On April 22, 2020, the Shaanxi Provincial Forestry Bureau announced that the rate of desertified land governance of Yulin has reached 93.24%.
In these deserts, the Taklamakan Desert located in the center of in Xinjiang, China is the largest desert in China and the tenth largest desert in the world. It is the second largest mobile desert in the world. The entire desert has an east-west span of about 1,000 kilometers, and the north-south span reaches about 400 kilometers. The entire desert has an area of 330,000 square kilometers. Because this desert is very large and the environment is harsh, some people call it the "Sea of Death". Compared with the Taklamakan Desert, the area of the other few deserts is relatively smaller.
From the perspective of territory, the scope of these deserts is very large. At present, the area of desertification in China is as high as 2.62 million square kilometers, accounting for about 27% of the country's land area. Moreover, it is still in a trend of continuous expansion. Looking at the whole world, about 48 million square kilometers of these arid, semi-arid desert and desert areas account for about one-third of the world's land area, of which desert areas account for 20% of the world's land area. Similarly, the area of the earth's desert is also expanding, expanding at a rate of 60,000 square kilometers per year. Therefore, whether for China or the whole world, controlling the desert is a very important thing.
Desert is being "eliminated"
"eliminated" the desert. On the one hand, the desert area is less rainy and dry. On the other hand, the soil in the desert area lacks organic fertilizer, and it is difficult to survive by planting vegetation. However, these are not difficult for us Chinese. The multi-functional three-dimensional sand fixing truck mentioned above is an expert in "eliminating" the desert.
In fact, before the emergence of multi-functional three-dimensional sand fixing trucks, we were already taking a series of measures to "eliminate" the desert. As early as November 1978, we launched the famous Three North Shelterbelt System Construction Project, and carried out a 73-year large-scale shelterbelt system construction project in the northwest, North China and Northeast regions. This is a world super ecological project. However, due to limited technical level in the early days, some work was often laid and planted by manpower, with relatively low efficiency and the survival rate of the plant cannot be guaranteed. After the emergence of the multi-functional three-dimensional sand fixing truck, it greatly improved the work efficiency and the survival rate of the plants.
Because the multi-functional three-dimensional sand fixing truck can not only plant plants directly underground, but also accurately control the depth of the plant insertion into the sand, but also directly irrigate the water source to the roots of the plant, greatly improving the survival rate of the plant. The most important thing is that our desert area is too large. If we rely solely on manual labor to complete the heavy work of "eliminating" the desert, it will take quite a long time.
You should know that a multi-function three-dimensional sand fixing truck can plant 2,000 plants in one hour, and plant planting in 40 acres of deserts can be completed in one day. If planting plants in 40 acres of deserts is manually completed, it will take a long time. It is precisely because the efficiency of the multi-function three-dimensional sand fixing truck is too high that it is called the "sand-swallowing beast" by some people and has now been put into use in Gansu and other areas.
We make the earth greener
Over the years, we have been committed to afforestation. In addition to the famous Three North Shelterbelt System Construction Project, many regions are also promoting afforestation. After decades of hard work, the greening area in China and even the whole world has changed greatly. Previously, Xinhua News Agency produced four episodes of "Satellite View of China", which showed us very intuitively the process of changes in China's afforestation from 2000 to 2021 through dynamic pictures.
According to data from scientists, from 2000 to 2017, the area of newly added green vegetation in the world was almost the same as the area of Amazon rainforest. Among them, China and India contributed as much as one-third in this regard. Our China contributed the largest, and nearly one-quarter of the newly added green area in the world came from our China.
You should know that at the beginning of New China, the forest coverage rate in China was very low, only 8.6%, and the forest area was only 80 million hectares. After decades of efforts, China's forest area has become larger and larger. In 2020, the forest coverage rate of has increased to 23.04%, and the forest area has increased to 220 million hectares. This is not the "end point". As we continue to plant trees and afforestation, China's forest coverage rate will be even higher. It is expected that the forest coverage rate will reach 24.1% by 2025.
Summary: In the past, when technology was not yet developed, we have taken measures to control deserts and deserts. After decades of efforts, China's green area and forest coverage have continued to increase. Especially the current situation is constantly emerging with advanced multi-functional three-dimensional sand fixing trucks or other equipment and facilities, which will help us promote tree planting and bring our forest coverage rate to a higher level.
