What are the five functions of turfgrass in regulating climate?

It can purify the air and absorb carbon dioxide, sulfur dioxide, hydrogen fluoride, ammonia, chlorine and other toxic and harmful gases in the atmosphere. 100m' grassland can absorb1500g carbon dioxide and release100g oxygen in10h. Lawn can adjust the temperature and humidity of the atmosphere. A hectare of lawn evaporates about 6300 kilograms of water every day, which increases the relative humidity in the air by 5%-9%. Lawn can be vacuumed and sterilized, and the dust absorption capacity of lawn is 70 times larger than that of bare lawn. Lawn can reduce noise pollution, and squares with larger lawns can reduce noise by 20? 0 decibels. Lawn can also protect water and resist drought, beautify the environment and adjust the climate.
