After that, the status quo of land desertification is introduced according to the previous research. 40% of the land around the world is arid land. This has caused a severe burden on people, desertification and poverty, and formed a vicious circle. At the same time, desertification threatens food production, affects biodiversity, and political stability, leading to immigration and causing and aggravating poverty. The causes of land desertification are divided into natural factors and human factors. Natural factors include drought, loose surface substances, wind erosion, no vegetation and improper activities such as the use of water resources. The human factor is that population growth and economic development put too much pressure on the land. Over-cultivation, over-grazing, deforestation and unreasonable use of water resources have severely degraded the land, the forest has been destroyed, the climate has gradually become dry, and finally, the land has been desertified. The form of land desertification is severe. There are four types of desertification in China: wind erosion desertification, water erosion desertification, permafrost desertification and soil salinization. According to the information released by the government department of the State Forestry Administration in 1998, China is one of the countries with the most severe desertification globally.

This thesis introduces land desertification from many aspects and makes a narrow and broad interpretation of land desertification. After that, the status quo of land desertification is introduced according to the previous research. 40% of the land around the world is arid land. This has caused a severe burden on people, desertification and poverty, and formed a vicious circle. At the same time, desertification threatens food production, affects biodiversity, and political stability, leading to immigration and causing and aggravating poverty. The causes of land desertification are divided into natural factors and human factors. Natural factors include drought, loose surface substances, wind erosion, no vegetation and improper activities such as the use of water resources. The human factor is that population growth and economic development put too much pressure on the land. Over-cultivation, over-grazing, deforestation and unreasonable use of water resources have severely degraded the land, the forest has been destroyed, the climate has gradually become dry, and finally, the land has been desertified. The form of land desertification is severe. There are four types of desertification in China: wind erosion desertification, water erosion desertification, permafrost desertification and soil salinization. According to the information released by the government department of the State Forestry Administration in 1998, China is one of the countries with the most severe desertification globally. |
