摘　　要：针对城市硬化地面面积增加带来的积水、内涝等问题,研究了将硬化地面改造成透水地面、壤土地面(若种植绿草则为绿地)后在增加雨水渗透量、减少径流外排量等方面的效果。试验表明,将硬化地面改造成透水地面、壤土地面后增渗减流效果显著,且改造成透水地面方式的下渗雨水收集率可达到30%~50%,高于改造成壤土地面方式(收集率很小或为零)。Targeting the urban waterlogging issues associated with urban impervious surface, infiltration enhancing and runoff volume reducing techniques were researched on impervious surfaces. The resuits showed that, the techniques were more effective when the impervious surfaces were changed to pervious surfaces or loam surfaces （could be changed to lawn if planting grass）. The infiltrated rainwater collected by pervious surfaces was up to 30% - 50%, which was higher than that of the loam surfaces （the collection rate was minimal）.
