抄録: The temperature of the surface layer of artificial and natural turfs defined as within 5mm below the surface, was investigated at Shiga-kita preschool from September to December in 2003. The correlation coefficients obtained by fitting the surface layer temperatures and the surface temperatures of artificial and natural turfs to regression lines were 0.963 and 0.877, respectively. There was a significant relationship between the surface layer temperature and the surface temperature of both turfs. The equations of regression lines were Y=1.02X (artificial turf) and Y=1.01X (natural turf), respectively. The surface layer temperature was significantly close to the surface temperature under the present conditions. The surface layer temperatures of the artificial turf were higher than those of the natural turf from September to December in 2003. On September 18 (summer), the surface layer temperature of the artificial turf was higher by 20.7℃ than that of the natural turf. The correlation coefficients obtained by fitting the surface layer temperatures of the turfs from the days after September 18 to regression lines were -0.993 (artificial) and -0.998(natural), respectively. The rates of decrease in temperature per day were 0.390℃/ day (artificial turf) and 0.267℃/ day (natural turf), respectively. The difference of the surface layer temperatures between both turfs decreased from 16.4℃ on September 18 (summer) to 4.5℃ on December 25 (winter).
