Every year, 50,000 to 70,000 square kilometers of land in the world become desertified by wind erosion. Mechanical damage caused by wind is manifested as lodging, branch breaking, drying, grain falling, fruit falling, etc. of trees and crops. Typhoon disasters in coastal and island areas are mostly mechanical damage. When the typhoon wind speed reaches 13 to 16 meters/second, the forest canopy will be damaged. The surface will be subject to a pressure of 15 to 20 kilograms per square meter, and shallow-rooted trees can be uprooted. The tidal wind in the southeastern coastal areas contains a lot of salt, which often affects plant pollination and pollen tube germination. It is a physiological hazard caused by wind.

Blind reclamation in arid areas will cause land desertification due to wind. Strong winds and snowstorms in pastoral areas can disperse livestock herds and aggravate freezing damage. Local winds, such as salty tidal winds blowing from the sea, foehn winds with high temperature and low humidity, and hot and dry winds, all seriously affect the flowering and fruit setting of fruit trees and the filling of cereal crops. Measures to prevent wind damage include cultivating wind-resistant varieties that are dwarfed, resistant to lodging and friction, building windbreaks, setting up wind barriers, etc. The strong winds in early spring in the north often cause wind damage to trees, causing partial crown and eccentric phenomena. Partial crowns will make tree shaping and pruning difficult and affect the performance of the tree's functions; eccentric trees are susceptible to frost damage and sunburn, affecting the normal performance of the tree. development.
