It took a lot of hardship, because the desert itself is devoid of greenery, which is particularly impressive.
-
It took the hardships of one generation after another. Not only to overcome the harsh environment of the desert, but also to overcome the psychological limits of this person.
-
The desert is not completely an oasis now, and the green area there is not particularly large.
-
This is true, because it is the sweat of generations who have been working day and night to build windbreaks and divert water to bring sand back to life.
-
It's really an oasis, and now it's full of trees, and it's very beautiful.

Located at the junction of Shaanxi and Inner Mongolia provinces, the Mu Us Desert is located in the north of the first line of the Great Wall of Yulin, Shaanxi Province, with a total area of 10,000 square kilometers. Introducing:
Location map of the Mu Us Desert.
In fact, the area where the Mu Us Desert is located was not a desert in ancient times, and the capital of the historical Xiongnu Bactria Kingdom, Tongwancheng, was built here. However, with the over-cultivation and wars in later generations, coupled with climate changes, the original grassland in the Mu Us area gradually turned into a desert, until it became an arid desert area in the Ming and Qing dynasties.

Since 1959, the Mu Us Desert has gradually reversed the trend of ecological deterioration by vigorously building windbreak belts, diverting water to pull sand, and diverting flood silt. By the beginning of the 21st century, about 80% of the Mu Us Desert has been treated, until recently, the Shaanxi Provincial Forestry Bureau released data showing that the desertification land management rate in Yulin, Shaanxi Province has reached, which means that the Mu Us Desert is about to "disappear" from the territory of Shaanxi.

The Mu Us Desert can be "wiped out", in addition to the silent efforts and efforts of generations of Chinese desert control people, it is also inseparable from "the right time and place". On the one hand, compared with large natural deserts such as the Taklamakan Desert (covering an area of 330,000 square kilometers), the Mu Us Desert is smaller and less difficult to manage.

On the other hand, the natural conditions of the Mu Us Desert are relatively superior. For example, the average annual temperature in the Mu Us Sandy Land is 22-24 in July, and the annual precipitation is 250-440 mm, and the maximum daily precipitation in summer can reach 100-200 mm. Relatively abundant precipitation and a mild climate are conducive to the survival of plants and make afforestation possible, which is also the basic condition for the transformation of the Mu Us Desert.
The forest and grass vegetation increased from 25%, and the wasteland of the Mu Us Desert became grassland. Saihanba is located at the junction of the Inner Mongolia Plateau and the northern mountains of Hebei Province, with a forest coverage rate of more than 90% and a survival rate of more than 90%. The yellow sand is long and the grass does not grow, this is the most vivid comment on the Kubuqi Desert in the past, and now the Kubuqi Desert is full of greenery and vitality, and has been recognized by the United Nations Environment Programme as a "Global Desert Ecological and Economic Demonstration Zone".
The Mu Us Desert in northern Shaanxi will disappear, and if the desert disappears, will it destroy the ecological balance? >>>More
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. >>>More
It has been predicted that in the 21st century, humanity will be able to turn most or all of the Earth's deserts into oases of abundant water and grass. Of course, it is not possible to shovel soil and dig ditches by hand, nor can it be to plant trees and set up obstacles. The methods used are "mega-engineering" and robots. >>>More
Desert animals, such as camels and scorpions, may face evolution or extinction, bringing changes up and down the biological chain. In addition, there are changes in climate and land, and China has 1.3 million square kilometers. >>>More
