Where is the desert in China?

The main deserts in China are Taklimakan Desert, Gurbantunggut Desert, Kumtag Desert, Qaidam Desert, Badain Jaran Desert, Tengger Desert, Wulanbuhe Desert and Kubuqi Desert from west to east.

China desert has a total area of about 700,000 square kilometers. If more than 500,000 square kilometers of Gobi are included, the total area is 6.5438+0.28 million square kilometers, accounting for 654.38+03% of the total land area of China. Northwest arid area is the most concentrated desert area in China, accounting for about 80% of the total desert area in China.

In the northwest of China, the north of North China and the west of Northeast China, there are sandy deserts covered by large sand dunes, Gobi deserts and gravel deserts composed of gravel, and rocky bare mountains called rocky deserts.

It is mainly distributed between 35 ~ 50 north latitude and 75 ~125 east longitude, and it is distributed in 7 provinces and autonomous regions such as Xinjiang, Qinghai, Gansu, Inner Mongolia, Shaanxi, Jilin and Heilongjiang. According to statistics, the total area of desert, Gobi and desertified land in China is about1308,000 square kilometers, accounting for 13.5% of the national territory. In desert areas, deserts dominated by mobile sand dunes account for more than 70% of the country's desert area.

Extended data:

Moisture in the desert provides:

① Natural factors: maintenance, expansion, expansion and water conservation of rivers, lakes and groundwater; Plant plants and trees with water storage and cold tolerance to protect the land and humidity in natural water source areas.

(2) Human factors: the construction of underground water network management, underground water network management is not easy to lose moisture due to air drying; Build artificial rivers and lakes at the underground water source, plant cold-resistant water storage plants and trees, and protect soil and soil moisture. You can also follow the example of oasis reversal method.

Cultivation of cold-tolerant plants

Cold-tolerant plants and trees are mainly plants or trees that can resist wind and sand, store water for a long time, and keep water in the surrounding soil and planted trees. As mentioned above, it should be expanded from water sources or artificial water sources.

Advantages of desertification reversal:

① The availability of land increases, and the soil gets enough water and nutrients.

(2) A large area of forest land can provide the source of trees and keep the growth rate of trees faster than the development rate.

(3) Trees provide more oxygen for living things, which helps to reduce the warming phenomenon.

(4) The windbreak protection of trees makes it possible to rebuild buildings in some areas where desertification is reversed, which increases the volume and utilization rate of land.

⑤ It can improve the environment, protect and care for animals and plants, and improve the harsh climate brought by the desert.

⑥ Absorb carbon dioxide and toxic gases, improve air quality and reduce greenhouse effect.

⑦ Help the sheath and the prosperity and development of the country.
