摘要
在降雨特性参数统计的基础上,提出了下凹式绿地蓄渗效率的概率分析方法,并结合上海市1985年—2004年的降雨特性参数统计结果,对上海市下凹式绿地的设计运行状况进行了探讨。鉴于下凹式绿地巨大的蓄渗效率,建议上海地区广泛使用下凹式绿地;当下凹式绿地的外排率达到2.5%时,其下凹深度宜为50～100mm。
Probability analysis method to calculate the rainwater storage and infiltration efficiency in low elevation greenbelt is put forward based on rainfall characteristic parameters, and the design and operation of low elevation greenbelts are discussed based on rainfall characteristic parameters from 1985 to 2004 in Shanghai. As a result of great storage and infiltration efficiency of low elevation greenbelt, it is suggested that the low elevation greenbelts should be widely used with a depth of 50 to 100 ram, when the rainwater discharge rate is 2.5 %.
