The United States released a photo over China, and the whole world froze. What is this?

When we mention the word "desert", we will definitely see the vast scenery beyond the Great Wall in Wang Wei's poem "the desert is lonely and the long river sets the yen"; Feel the heroic spirit of the frontier fortress soldiers who swear to the death to kill the enemy in Wang Changling's poem, "Yellow sand wears golden armor and fights hundreds of battles, but never breaks Loulan and never returns";

Experience the emptiness, sadness and loneliness of Wang Zhaojun, one of the four beauties in China, in Du Fu's poem "She left the Purple Palace and went to the desert, and now she has become a yellow grave".

But in real life, we may not feel the poet's feelings for the ancients so easily. That's because in the pictures of China monitored by American satellites, we are surprised to find that the desert area in northwest China is decreasing, and oases and grasslands are gradually appearing, accounting for most of the world. China's desert management ranks first in the world!

At that time, after the photos were made public, the environmental protection departments of various countries were extremely shocked and felt that China was indeed the first desert control country. The problem of desert control has plagued countries for many years, and the plans made have failed repeatedly, and it is not easy for other countries. The success of desertification control in China has made China take a big step forward in the world.

Desert control is imminent.

Nowadays, we have been enjoying the convenience brought by technology. However, have we ever thought about the price that mankind will face while technology brings convenience? The occurrence of this phenomenon has begun to make people think deeply and fear.

At present, the threats of environmental problems to our human survival mainly include global warming, shortage of fresh water resources, endangered rare species, land desertification, serious industrial pollution, garbage disasters and many other aspects. Land desertification has become one of the most serious disasters in a series of environmental problems faced by human beings.

Land desertification means that people have lost the land for planting crops and the guarantee of survival, so it is urgent to control land desertification.

In recent years, countries have also put forward desert control's suggestions and made efforts to improve environmental problems, but the results have been minimal. It was not until the satellite survey in the United States found that a photo of the earth's surface showed that the desert area of desertification land in northwest China and Inner Mongolia Autonomous Region was gradually decreasing, which was due to China's unique desertification control model.

For example, the Three-North Shelterbelt is a major project facing the problem of ecological environment protection in China, involving almost 90% of sandstorm areas and more than 40% of soil erosion areas in China. As can be seen from the data, the construction project of the Three-North Shelterbelt is an important link in the success of desert control in China.

In the early stage, the scope of desertification control in China was mostly concentrated in desert areas that were easy to control. Later, China will control severe and extremely severe desertification areas that are "easy to repeat and difficult to control".

In addition, the construction of shelterbelts has effectively improved local agricultural production activities. According to statistics, the grain output of low-yield farmland in shelterbelt engineering area has increased by more than 10%. Therefore, China's desertification control plan has little effect. Desertification control is an important requirement of ecological civilization construction in China, and it is also a problem that must be solved in the future ecological civilization construction in China.

China's plan has achieved remarkable results.

As one of the countries with the most serious desertification problem in the world, China is trying to solve the ecological and environmental problems.

Since the 1980s, a research system on the causes of desertification and its control countermeasures has been established, and a series of ecological environment construction projects for desertification control, which have important influence in China and even in the world, have been continuously carried out, such as the construction of the Three-North Shelterbelt System, the natural forest protection project and the project of returning farmland to forests and grasslands.

To our delight, with the joint efforts of researchers and natural factors. Great changes have taken place in desertification areas of China. The area of desertified land decreased from 65438+267. 4Mhm2 in 0999 to 2065438+26 1. 04 1Mhm2. The smog weather phenomenon in the north has dropped significantly, and the scene of blue sky and white clouds has gradually increased.

Among them, Mu Us Desert in Yulin City, Shaanxi Province is the most significant area for desertification control. According to the latest data, the desert control rate of Mu Us Desert in Yulin City, Shaanxi Province has reached more than 90%, which means that Mu Us Desert will "disappear" from people's sight, but what makes people happy is the rare grasslands and oases.

China's desert control has accomplished an impossible task in the eyes of the world, which makes other countries sit up and take notice. The success of desert control has become a classic case in the history of human desert control.

However, the successful management of Mu Us Desert is not only the only case in China, but also a similar case has appeared in the desert area of China.

In terms of research results, the researchers of desert control in China did not have blocking technology in the face of the success of desert control, but conducted academic exchanges and discussions with professionals from various countries at international academic conferences, and also shared some successful cases of their own desert control, hoping to give some experiences and methods to countries that need desert control.

I believe that in the future of China and even the world, there will be examples like the Mu Us Desert.

Ecological construction and harmonious life

Desertification may be natural. However, most of the causes of desertification around the world today are attributed to human factors. It is precisely because of a series of unreasonable human activities such as excessive logging, excessive reclamation of wasteland and excessive exploitation of mineral resources that the ecological environment will be destroyed.

For example, Mesopotamia was one of the earliest areas to develop agriculture. The development of this area benefits from the unique geographical environment, fertile soil and abundant rainfall. However, due to the overuse of resources by local people, the exploitation of upstream rivers and deforestation have had a bad impact, leading to soil erosion and flooding.

This is also the status quo of the world's environmental problems. Similarly, desertified land is gradually destroying our environment and even civilization.

Before that, human beings have been destroying the environment, such as deforestation, piles of garbage, white pollution and so on. Therefore, at present, our most important task is to protect our ecological environment and protect our home on earth.

Start from our side, start from the dribs and drabs of life. Strive for the construction of ecological civilization, strive for social harmony and strive for harmony with nature.
