- 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.
