Building protective forest belts in wind-damaged areas can reduce wind speed by about 30% within the protection range; farmland with protective forest belts will increase yield by about 20% compared with those without. In Chifeng City, Inner Mongolia, 110,000 acres of forest have been planted in 40 years, and nearly a thousand sand dunes have been fixed. The number of annual sandstorm days has been reduced from 3.7 to 1.5 days, and the annual sand blowing days have been reduced from 54 to 20 days.
The maximum wind speed dropped from 40 meters/second to 17 meters/second. The total leaf area of ??a forest can reach 75 times the area it covers. A mature whitebark pine has about 6.6 million needles. The total leaf area of ??an adult linden tree is more than 30,000 square meters. The needles of a 165-year-old pine tree The total length can reach 250 kilometers.
Such a large leaf area, coupled with some hairy structures on the leaves, has a great adsorption effect on dust. According to calculations, on green streets, the dust content in the air is 56.7% lower than in areas without greening; the amount of dust above grass is only 1/6 to 1/3 of that on bare ground.
