城市道路低影响开发设施的比选与布局研究

The Layout and Comparison of Low-impact Development Facilities in Urban Roads

城市道路作为重要的城市基础设施应在海绵城市建设中充分发挥功能。通过对各类低影响开发设施的功能和结构的分析,对适用于城市道路的低影响开发设施进行比选,并对单项设施在城市道路上布局的适宜性进行了解析。结合城市道路结构和排水特点,探讨道路绿带、交通岛绿地、交通广场绿地、停车场绿地和路面等各城市道路部分的低影响开发设施布局设计方法,以期对今后低影响开发理念下的城市道路景观设计进行指导。

As an important urban infrastructure,urban roads should play full roll to its functions in the construction of sponge cities.Based on the analysis and summary of the functions and structural characteristics of various low-impact development facilities mentioned in the Technical Guidelines for the Construction of Sponge Cities,we compare the low-impact development facilities suitable for urban roads,and analyze the suitability of the layout of individual facilities on urban roads and the matters needing attention.Combining with the structure and drainage characteristics of urban roads,the layout design method of low-impact development facilities of green belt,traffic island green space,traffic plaza green space,parking lot green space and pavement is studied,so as to guide the landscape design of urban roads under the concept of low impact development in the future.
