The Mu Us Desert will disappear from the map of China. Planting trees is the duty of citizens. How many trees do you owe?

It's a good thing that the Mu Us Desert has been erased from the map.

As we all know, the Yellow River has a large sediment concentration, with an average annual sediment discharge of about10.60 billion tons. About one third of all the sediment in the middle and upper reaches of the Yellow River is contributed by the Mu Us Desert. However, on the day of Arbor Day, that is, March 2002112, the media indicated that the Mu Us Desert would be the first desert in China to be wiped out by human flesh and the first desert to disappear on the map of China.

Without human intervention, the former Mu Us Desert once expanded southward, not only crossing the Great Wall, but also directly devouring more than one million mu of farmland and pasture, which is why its sediment can still flow into the Yellow River. Fortunately, all this ended because of the anti-desertification project in China. Not only has there been no further soil erosion in this area, but the sediment flowing into the Yellow River has decreased by about 400 million tons every year, and more than 6 million mu of sandy land has been successfully managed.

Mu Us Desert is located in Yulin City, Shaanxi Province. Yulin is also called Camel City because it is a desert city. The Mu Us Desert, located to the north of the Great Wall, covers an area of 42,200 square kilometers. There used to be many large sand dunes in the Mu Us Desert, some of which were fixed and some were semi-fixed. It's time 1959, and China began to transform this desert, and then turned the once desert capital into today's desert oasis.

Who is responsible for the management achievements of the Mu Us Desert? How difficult is it to prevent and control desertification?

Desertification control can never be achieved by shouting slogans. If human society wants to achieve a longer-term sustainable development, then curbing land desertification and controlling desertified land is one of the most useful ways to maintain the stability of the earth's ecosystem. Statistics show that:

As of February 7, 20021year/kloc-0, China has completed the task of desertification control100000 hectares after the 13th Five-Year Plan, of which130000 hectares is a rocky desertification control area. At present, the overall ecological environment of the four sandy lands in China has been improved to some extent, and the degree of rocky desertification has also been greatly improved.

As we all know, the great change of global climate will inevitably lead to more natural disasters, and this trend will also highlight the problem of land desertification, especially some human production activities will even aggravate this change. Therefore, blind reclamation and overgrazing must be avoided, and scientific prevention and control should be carried out in desertification areas.

At the same time, the water resources in these places are generally scarce, and the limited water resources should be rationally utilized. Flood will not only salinize the land, but also waste water resources. After over-exploitation of groundwater, the groundwater level will drop, which will naturally make the planted plants face the risk of death.

There is no doubt that the governance of the Mu Us Desert is successful, and this credit belongs to all sand control people and the powerful motherland behind us. With the persistence and management of China, the environment in Mu Us Desert has been improved, the rainfall has increased, and the former desert has turned into fertile fields, grasslands and woodlands. In the hinterland of the desert, more than one million mu of farmland was newly reclaimed. I have to say that such a change is really worthy of applause.

Why is it the duty of citizens to plant trees? How many trees do you owe?

How many people know that as early as 19 15, China foresters represented by Ling Daoyang, Han An and Joseph Bailie initiated the establishment of Arbor Day in China, and the first Arbor Day was held in Tomb-Sweeping Day every year. Later, this Arbor Day was twice designated as March 12 every year.

Do you know that?/You know what? In fact, everyone already owes a lot of trees! Forty years ago, it was stipulated that all citizens should plant three to five trees every year. As long as they are qualified to plant trees and are over 1 1 years old, as long as they are not old, weak, sick and disabled, they should complete this basic greening task.

Although it is true that many people can plant trees together on Arbor Day every year, how many people will plant trees in most other life time if they are not special forest rangers? Nowadays, global warming is a problem that everyone faces, and afforestation is not only a new production activity of forests, but also benefits ourselves and future generations by cultivating forests.

Afforestation is not only beneficial to soil and water conservation and sandstorm resistance, but also can eliminate air pollution. Specifically, from absorbing dust and carbon dioxide to releasing oxygen, green plants are like oxygen factories. It takes only one day for a hectare of broad-leaved forest to release 700 kilograms of oxygen, which is the basic condition for most living things on earth to thrive.
