The Impact Of Artificial Turf On Climate

The natural lawn bed is a mixture of sediment, with sufficient pores in the structure to accumulate water during irrigation and precipitation, playing a role in conserving water sources. When the climate is hot, lawn grass uses its roots to absorb water from deep within, taking away a large amount of heat from the surrounding environment through transpiration, effectively reducing ground temperature and regulating the microclimate within a certain range. The bed structure of artificial turf is composed of rubber, concrete, or asphalt, which cannot effectively conserve water sources. Therefore, it cannot lower the surface temperature, and its small heat capacity leads to a significantly higher surface temperature than the air temperature, especially in enclosed sports fields where this problem is more serious. At noon in summer, significant heat distortion can be observed in the air near the surface of artificial turf fields. Experimental data shows that under high temperature conditions above 30 ℃, the average surface temperature of natural lawns is 2 ℃ to 3 ℃ lower than the temperature, while the surface temperature of artificial lawns is 6 ℃ to 11 ℃ higher than the temperature. Moreover, as the temperature increases, the surface temperature of artificial lawns increases significantly more than that of natural lawns. In summer, the surface temperature of artificial lawns is very high. If users experience intense friction with them at this time, the skin at the contact area will be seriously injured.
