- 摘要:
- 近年来，随着极端强降雨天气的不断侵袭，全国各地内涝积水问题日益突出。国家多次发布重要文件提出了排水防涝工程、建设海绵城市和韧性城市的重点工作内容，将内涝防治工作提升到重要高度。系统性梳理了城市内涝防治体系，密切结合城市空间和城市活动，针对内涝防治规划思路提出了“问题导向，对症下药”“灰绿结合，系统治理”“竖向衔接，空间协调”三方面的综合性举措。同时结合城市空间布局的分类等级，针对居住街坊、五分钟~十分钟生活圈、十五分钟生活圈和区域四个尺度的居住区提出排涝工作的规划建议。并以天津市某典型汇水分区为例，进一步对城市内涝防治观点进行详细论述与说明。
- Abstract:
- In recent years, with the frequent occurrence of extremely heavy rainfall, the problem of waterlogging in all parts of the country has become increasingly prominent. According to the recently released public documents, the key tasks of the construction of drainage and waterlogging prevention project, sponge city and resilient city was proposed. Urban waterlogging management has been mentioned to a more important position. This paper combed the urban waterlogging prevention system and put forward three comprehensive measures that closely combined with urban space and city activity. The first one is problem-orientated, which is the antidote to disease. Secondly, paying attention to the combination of grey and green infrastructure and system management is particularly important. The third is to do a good job in the vertical connection and the coordination of space. According to the four scales of neighborhood block, 5-10 minute pedestrain-scale neighborhood, 15 minute pedestrain-scale neighborhood and regional scale, combined with the classification level of urban spatial layout, this paper puts forward some planning suggestions for drainage and waterlogging prevention. Finally, a typical watershed in Tianjin was taken as an example to further discuss and explain.
