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.

The total area of desert in China is about 7, square kilometers, and if the Gobi with more than 5, square kilometers is included, the total area is 1.28 million square kilometers, accounting for 13% of the total land area in China. The arid area in northwest China is the most concentrated desert area in China, accounting for about 8% 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 desert and gravel desert composed of gravel and gravel, and rocky exposed mountains called rocky deserts or stony deserts.

they are mainly located between 35 ~ 5 north latitude and 75 ~ 125 east longitude, and distributed in seven provinces and regions, including Xinjiang, Qinghai, Gansu, Inner Mongolia, Shaanxi, Jilin and Heilongjiang. According to statistics, the total area of desert, Gobi and desertified land in China is about 1.38 million square kilometers, accounting for 13.5% of the country's land area. In the desert area, the desert dominated by mobile sand dunes accounts for more than 7% of the country's desert area.

Extended data:

Water supply in desert:

① Natural factors: river and lake maintenance and groundwater maintenance, extension, expansion and water conservation; Planting water storage and cold-resistant plants and trees to protect the land and humidity in natural water source areas.

② Man-made factors: the construction of underground water pipe network makes it difficult for dry air to make water lose; Create artificial rivers and lakes at underground water sources and plant cold-resistant water storage plants and trees to protect soil and soil moisture. You can also follow the example of oasis reversal method.

planting of cold-resistant plants

cold-resistant plants and trees are mainly plants or trees that are resistant to wind and sand and can store water for a long time, and retain water in the surrounding soil and planting trees. As mentioned above, it should be expanded from water sources or artificial water sources.

Advantages of desertification reversal:

① The availability of land is increased, and the soil gets sufficient water and nutrients.

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

③ Trees provide more oxygen for living things and help reduce the warming phenomenon.

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

⑤ It can improve the environment, protect and cherish animals and plants, and improve the bad climate caused by desert.

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

⑦ help the sheath zone and the prosperity and development of the country.
