摘　　要：从径流控制机理出发,阐述了降雨过程中下沉式绿化带的雨水渗透和雨水量调蓄作用,指出市政道路中下沉式绿化带的设计应结合场地条件和降雨雨型,从年径流总量控制、径流峰值流量控制、径流污染控制3方面校核设施的径流控制能力。通过实例分析,为下沉式绿化带在市政道路设计中的应用提供理论基础。Based on runoff control mechanism, this paper demonstrates rainfall penetration and rainfall regulation and storage of sunken green belt in the process of rainfall, points out that it should be designed in combination with ground and rainfall type, and checks runoff control capacity of facilities from 3 aspects of total annual runoff control,runoff peak control and runoff pollution control. That example analysis provides theoretical basis for application of sunken green belt in municipal roads design.
