Mongolia has become the center of sandstorm. Why is the local climate always so bad?

1) Natural conditions of drought, Mongolia is inland, with an average annual precipitation of about 230mm and 500mm, which can reach 500mm in the north, less than 50mm in the south and below 200mm. Without planting trees and natural conditions, the conditions for building factories can only be presented in the desert. This dry and desert condition, combined with the spring wind, will inevitably form dust.

2) Overgrazing, Mongolia's annual water volume of 230mm is not enough to feed fertile pasta, but in 20 19, the number of livestock in Mongolia has reached 70.9 million, far exceeding the national pasture environmental carrying capacity by 2-7 times and 2-7 times. Grazing makes 3/4 of the country's land face desertification, and 40% of the land is already desert. At present, there are sandstorms in about 1/33 years, and the sandstorm force has reached four times that of the 1960s.

3) Climate change, climate change gives desertification. Under the action of "fire", the temperature rise in inland areas is twice as high as that in the world, and it has been rising since 1940 in Mongolia. C, the higher the temperature, the more serious the evaporation, which leads to the more serious drought. Desertification has the functions of "promoting prosperity" and "adding fuel to the fire".

According to the previous research papers in June 5438 +065438+2020 10, the high temperature and drought experienced by Mongolia in recent 20 years is unprecedented in recent 260 years (part two). Because the higher the temperature, the greater the drought, the more serious the drought and the higher the temperature, there is a heating feedback between warm and dry. This paper holds that Mongolia may criticize climate change, and if it is global climate change, the warming trend will not be reversed.

Overgrazing and climate change are caused by human activities. The rampant hourglass activity has sounded the alarm for mankind. They need to be kind to nature. Only by improving the natural environment can there be sustainable economic development. Let's go back to that sentence: Lucid waters and lush mountains are invaluable assets.
