Aiming at the effect of permeable pavement, especially on hydrology and thermology, a longterm monitoring was carried on the site for half a year to know how the permeable pavement works in rainstorm runoff suppression under ground water taking, and how the temperature of the ground surface drops, as well as the duration of temperature decrease.It was found that when the amount of rainfall on the rain field was smaller than 35mm, the infiltration efficiency went up to 80% and above.As for thermology, the temperature of permeable pavement decreased continually for two days under the temperature of 19~23℃.
