| 摘要: |
| 道路是城市硬质化下垫面的重要组成部分，它既是居住小区雨水径流的主要来源，也是雨水排放的重要通道，因此居住小区中道路系统与雨水产汇流过程关系的探究对于居住小区雨洪韧性的提升具有重要意义。以天津居住小区为例，借助ArcGIS和SWMM，探讨不同降雨强度下分别具有网格型、尽端型以及环网型、环尽型道路布局模式特点的居住小区产汇流规律，并以此为依据提出以雨洪韧性导向为目标的居住小区道路系统布局优化策略。 |

| Abstract: |
| As a major component of hard underlying surfaces in a city, roads in communities are main sources of runoff and important channels for runoff discharge. Therefore, it is of great significance to explore the relationship between community roads with the runoff generation and concentration process, which helps to improve the stormwater management resilience of communities. Taking the communities in Tianjin as examples, this paper further discusses the whole process of runoff generation and concentration in four types of road layouts, which are the square grid type, cul-de-sac type, circular-gird type and circular-cul-de-sac type under different rainfall events by ArcGIS and SWMM software. The results provide useful and reasonable references and suggestions for the optimization of community road layouts to prevent flooding and support the establishment of sponge cities. |
