摘　　要：对北京城区不同水平年、不同集水面积和不同下凹深度的绿地雨水蓄渗效果进行了分析和计算 ,结果表明 ,城市建设中采用下凹式绿地是利用城市雨水资源 。It is an efficient approach that using the hollow grassland to increase rainfall infiltration and reduce the amount of water flow out during the rainy season. The ability to infittrote rainfall with different depth of hollow grassland in different hydrological years were analyzed and calculated. It is indicated that constructing hollow grassland is an efficient approach to increase rainfall use and protect or reduce flood disaster in cities.

关 键 词：下凹式绿地 雨水蓄渗 蓄渗效果 城市建设 北京市
