下凹式绿化带是一种生态的市政道路排水技术，主要通过强化雨水渗蓄作用优化市政道路排水。下凹式绿化带所占面积比例、绿化带的下凹深度、绿地土壤稳定入渗速率和设计暴雨重现期是下凹式绿化带的重要设计参数，对下凹式绿化带的应用效能有很大影响。下凹式绿化带的应用可以有效减少城市暴雨洪峰流量、降低城市内涝的发生频率，对于解决城市初期雨水污染、增加城市地下水资源、节约道路绿化灌溉用水等方面也都具有重要作用。

The Concave-down green belt is an ecological drainage technology for municipal road,which optimizes the drainage mainly by improving the ability of rain permeability and storage, and its area percentage, concave depth, soil steady infiltration rate and the designed rainfall reappearing period are important design parameters for the concave-down green belt,which have important effect on its application performance. The concave-down green belt can effectively reduce the flood peak flow of urban storm and reduce the frequency of urban water logging,and it also plays an important role in solv-ing urban rainwater pollution, increasing the urban groundwater resources and saving the irrigation water, etc.
