Abstract
Natural lawn and artificial turf, which have a great difference on practical function and thermal environment characteristics, are widely used in sports field. In order to obtain the quantitative differences on thermal environment in summer, instrumental measurement and questionnaires are used in this paper to investigate the thermal environmental characteristics of natural lawn and artificial turf, respectively. Meanwhile human thermal sensation in the two lawns was also evaluated. The results show that the foliar surface temperature and mean air temperature in artificial turf is significantly higher than that of natural lawn in early summer. Due to thermal discomfort and the potential hurt for athletes on artificial turf field, cooling methods such as sprinkle are recommended.
