摘　　要：雨水花园是一种有效的雨水自然净化与生物滞留处置技术。对目前国外雨水花园常用的三种设计方法进行了对比和分析,包括:基于达西定律的渗滤法、蓄水层有效容积法和基于汇水面积的比例估算法。根据我国多数城市雨水花园的建造特点,提出了一种基于水量平衡分析的设计方法,为雨水花园的设计提供参考。Rainwater garden is an effective nature purification and bio-retention technology for stormwater management. In this article, three popular design methods in foreign countries were compared and analyzed, which were infiltration method based on Darcy＇s Law, effective volume method of surface retention layer, and proportion estimation method based on catchment area. Moreover, considering the structure characteristics of rainwater gardens in China, a design method based on water balance was proposed, providing a fundamental idea for the design of domestic rainwater gardens.
