Abstract
[Objective]Shenzhen and other mega cities have entered a new stage of developing existing land.In the new situation of tight constraints on urban land space development,to solve the problem of difficult implementation of urban waterlogging control facilities caused by tight land space,and effectively respond to the increasingly severe urban waterlogging control problem under the background of frequent extreme rainstorm events.[Methods]This paper was explored the integration of the concept of"dual-purpose of daily and emergency situations"into the planning and construction of flooding prevention and control facilities,and systematically promoted the planning and construction of"dual-purpose of daily and emergency situations"flooding prevention and control facilities in multi-functional spaces or multi-functional compatible modes.On the basis of accurately understanding and grasping the connotation of"dual-purpose of daily and emergency situations",drawing on typical cases,highlighting the concept of composite integration,and comprehensively balancing the relationship between safety and efficiency,this paper was explored the integration of urban waterlogging control facilities into urban planning paths.[Results]The overall framework of"3+3+7"was systematically proposed,which included three principles of"safety,efficiency,and function",three construction modes of"one land for multiple purposes,one channel for multiple purposes,and one building for multiple purposes",and seven specific construction types of"flood storage and detention areas and wetlands,multi-functional rainwater storage spaces,multi-functional underground tunnels,emergency flood discharge roads,flood control leisure rivers,high-altitude emergency shelters,and tsunami emergency shelters".And Shenzhen was taken as an example for certain exploration and practice.[Conclusion]The"dual-purpose of daily and emergency situations"facilities are of great significance in solving urban waterlogging problems,especially in built-up areas with limited land space.By embedding different ways such as space and function,new solutions can be provided for solving urban flooding problems.关键词
