Why do shelterbelts have the function of regulating local climate?

1, the lack of plants on the ground and the rise of the earth's temperature lead to the melting of glaciers, rising sea levels and flooding villages.

2. The surface soil lacks vegetation protection, the land is desertified, and natural disasters such as mudslides will occur in case of heavy rain.

3. Without plants absorbing carbon dioxide, oxygen will not be produced, and the oxygen in the atmosphere will be exhausted, which will directly lead to human extinction.

4. The ecological environment of human beings has been destroyed, and the climate will become very bad, with smog all over the sky and no clear sky.

Cutting down trees is easy to cause sandstorms. Without the protection of vegetation in desert areas, the desert will soon become a desert, which greatly increases the difficulty of governance. Shelterbelt can slow down the wind speed, and its effective range is less than 40 times of the tree height, and the best effect is in the range of 10 ~ 20 times, which can reduce the wind speed by 50%.
