摘　　要：给出了不同空气温度条件下,天然草坪与人造草坪随太阳辐射强度变化的理论计算地表温度.通过对西安地区的实际测试,得出理论计算草坪表面温度与实测值吻合较好.通过数据分析发现人造草坪表面温度受到太阳辐射的显著影响,太阳辐射强度在200W/m2-800W/m2之间变化,人造草坪表面温度升高幅度接近30℃,而相应天然草坪表面温度升高幅度不超过15℃,并阐明随着太阳辐射强度的增加,天然草坪蒸发潜热吸收热量绝对值增加.Under different air temperature, the theoretical calculation surface temperature with different solar radiation of artificial turf and natural lawn in the sports field are given in this paper. The theoretical calculation surface temperature is fit to the surface temperature of actual test. Through analysis of the data, the remarkable difference of surface temperature of artificial turf with different solar radiation is found. The surface temperaturer of artificial turf reaches 30℃ when solar radiation changes from 200 W/me to 800W/m2. And the change of surface temperature of natural lawn is less than 15 ℃. It is clarified that the absolute values of evaporation heat increase with the stronger solar radiation.
