摘  要:
下沉式道路绿化带是一种生态环保的雨水渗蓄设施,响应了"海绵城市"的建设理念。介绍了下沉式道路绿化带的应用背景,了解下沉式道路绿化带的形式及功能,并通过对下沉式绿化带雨水渗蓄能力及影响因素进行分析,总结了下沉式绿化带的适用性。结果表明,在长沙地区道路绿化率在30%,年径流总量控制率达到100%的条件下,满足暴雨重现期1、3、5、10 a的下沉深度分别为147、186、204、229 mm,比较适合设计下沉式道路绿化带。最后探讨了下沉式绿化带竖向设计、道路绿化率设计、植物耐水淹分析及植物种类的选择。

摘  要:
Sunken road greenbelt is an eco-friendly facilities of rainwater penetration and storage in response to the construction concept of "sponge city". The application background of the sunken road greenbelt was described, and the form and function of sunken road greenbelt was comprehended, through the analysis of the rainwater penetration and storage capacity of the sunken road greenbelt and its influencing factors, the applicability of sunken green belt was summed up. Results showed that, Changsha is suitable for design sunken greenbelt, the rate of road green space is 30%, under the condition of the control rate of total annual runoff more than 100%, when the return period of rainstorm for 1, 3, 5 and 10 a, the proper sinking depth of the sunken greenbelt are 147, 186, 204 and 229 mm. Finally, the vertical design, road greening rate design,plant waterlogging time and plant species selection of the sunken road greenbelt were discussed.
