Research On The Form Evolution Mechanism And Resilience Development Of Urban Underground Space In The Four Districts Of Qingdao East Coast

The development and utilization of urban underground space plays an important role in improving the efficiency of land use,effectively expanding the three-dimensional use space of the city,and improving the urban environment.At the same time,urban underground space has become an important pillar of resilient urban development due to its good concealment and strong anti-interference ability,and plays a pivotal role in urban development.In addition,underground space is of great significance to energy conservation and green development,and it is related to my country’s carbon-neutral century development plan.Despite the rapid development of my country’s underground space scale,rich types of utilization,and significant comprehensive benefits,it also faces problems such as systematic inadequacy and planning formulation lagging behind urban construction and development practices.Systematically summing up the planning and design method of underground space is a realistic problem that must be faced and solved as soon as possible.By studying the form of underground space,we can sort out different forms of underground space,and study the influencing factors and dynamic mechanisms behind them,and use the form of space as the starting point to systematically study underground space.Qingdao is one of the earliest open port cities in my country.The construction of underground space started earlier and has a huge amount.However,the old underground space in the past can no longer meet the diverse and resilient development needs of the current city,which has led to the separation of underground space and urban development.Therefore,this paper first classifies the urban underground space in the four districts of the East Bank,discusses the distribution characteristics of the underground space,explores the deep elements that affect the shape of the underground space,and from the perspective of space,divides the underground space in the four districts of the East Bank into microscopic and mesoscopic.,Macro three levels,analyze its characteristics and complexity.Secondly,using self-organization theory,analyze the evolution motivation,development stage,evolution trajectory and specific morphological elements of the underground space form in the four districts of the East Bank from micro,meso to macro,analyze the complex relationship between the underground space form and various urban elements,and summarize Morphological development characteristics of underground space at all levels.Subsequently,through the questionnaire,the main problems and internal needs faced by the cities and underground space development in the four districts of the east coast were found,and based on the problems,needs and new opportunities,the goal framework and resilient development strategy for the resilient development of the underground space form in the four districts of the east coast were proposed,Underground space form design methods and practical approaches.Finally,by referring to the self-organization theory,the long-term mechanism of the sustainable development of urban underground resilient space is summarized,and representative cases along Qingdao Bay are selected for underground space design,and the resilience design method is selected according to the design requirements to test the feasibility of the strategy.
