There are three miracles of turning China s desert into an oasis, what are these three miracles?

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".

A typical example of a desert turning into an oasis is the Mu Us Desert. The Mu Us Desert is a well-known barren land with yellow sand, but after transformation, it has been planted with large poplar forests.

These three miracles are desertification, which also includes desertified land, and the last is that the Mu Us Desert is getting smaller and smaller, changing the local soil structure and weather.

Mu Us Desert.

"Mu Usu" means "bad water" in the Mongolian language, that is, the place where the plant does not grow. Our country has been managing this desert since 1959, and after 60 years of governance, the once barren land of the Mu Us Desert has become a green kingdom.

The Mu Us Desert is located in the north of the first line of the Great Wall of Yulin, Shaanxi Province, so Yulin City is also known as the Camel City, which means the city of the desert, and the Mu Us Desert covers an area of about 10,000 square kilometers. Yulin City, which is located on the front line of desertification prevention and control, has continued to carry out large-scale desertification control and afforestation campaigns for more than 60 years, increasing the city's forest preservation area and forest coverage rate from 600,000 mu at the beginning of the founding of the People's Republic of China and 21.57 million mu and 33% at present, respectively. Turning a desert into an oasis may sound like a fantasy, but the celery attack on NASA (NASA) data shows:

Over the past 20 years, the Earth has been turning greener. China alone has accounted for at least 25% of the total global vegetation increase over the past 17 years.

If you open the map and take a look, you will see that most of the oases are buried in the mountains and face the desert. The high mountains are a world of snow and ice, covered with snow all year round.

In the summer, the snow melts in the mountains, and the melted snow water flows into rivers. When the river flows on the Gyeongdaeba, the terrain is steep and the water is turbulent, and it can carry a large amount of sand and gravel, and even very large stones can be carried. However, after leaving the pass, the terrain suddenly becomes flat, the speed of the river decreases sharply, and the ability to carry sediment is greatly reduced, and the larger stones are deposited first, and then the finer stones and sediment are also deposited and piled up near the pass.

At the same time, due to the seepage and evaporation of water along the way, many rivers often cannot flow all the way to the center of the desert, except for rivers with large volumes that can flow farther, and they hide in the sand and pebbles halfway through, becoming groundwater, and it is easy to form oases when there is water. People living in desert areas have long used river water or exploited groundwater to irrigate crops for residents and livestock to drink. Therefore, places on the edge of the desert with high mountains in the background are often oases.

The Seven Wonders of the Ancient World.

1 Pyramid of Huwan, Egypt.

2 Olympian Tomb touches the Colossus of Azeus.

3 Temple of Artemis.

4 Mosolasky Mausoleum.

5 Alexander talks about the lighthouse.

6 The Hanging Gardens of Babylon.

7 Colossus of the Sun God of Rhode Island.

The Hanging Gardens, one of the Seven Wonders of the World, are buried by the desert.

The desertification situation in China is very serious. According to the materials published in 1998 by the Office of Desertification Prevention and Control of the State Forestry Administration, China is one of the countries with serious desertification in the world. According to the results of the national desert, Gobi and desertification land census and desertification survey, China's desertified land area is 10,000 square kilometers, accounting for nearly 400 million people in China's land area.

According to the analysis of Landsat images of 17 typical sandy areas in China at different times in the same place, it also proves that the development situation of desertification in China is very serious. Located at the junction of Inner Mongolia, Shaanxi and Ningxia, the Mu Us Sandy Land covers an area of about 40,000 square kilometers, and the area of quicksand has increased by 47%, the area of forest land has decreased, and the area of grassland has decreased by 17% in 40 years. Due to overgrazing and firewood cutting in the southern part of the Hunshandak Sandy Land, the area of quicksand has increased and the area of grassland has decreased in just nine years.

In addition, the shrinkage of the Minqin Oasis in Gansu Province, the extinction of poplar forests and red willow forests in the lower reaches of the Tarim River in Xinjiang, and the degradation of grasslands and the disappearance of Suoxon forests in the Alxa region of Gansu Province ......A series of grim facts.

It used to be a herdsmen's settlement, and later it became a desert, but it is about to become the first desert in China that is about to disappear, an area larger than Hainan Island, and now 80 oasis.

Mu Us Desert. Today, 80% of the Mu Us Desert has become an oasis, and at this rate, the desert will soon disappear.

Mu Us Desert. Due to the abundant precipitation and the management of this desert, the area of this desert is gradually shrinking.

He is the Mu Us Desert located north of the first line of the Great Wall of Yulin, Shaanxi Province. Since 1959. China began to prevent wind and sand fixation, build windbreak forest belts, and began a huge project of afforestation, and now 80% of the area of the Mu Us Desert is covered by trees, becoming the first desert in China that is about to disappear.
