The urban public open space regeneration from the perspective of pop-up urbanism: An example in Liuyun Community

Since the economic crisis in 2008, economic growth has slowed down worldwide and construction projects for new cities have decreased. The research trend in the urban field has gradually shifted towards the regeneration and regeneration of existing areas. In recent years, pop-up actions have been gaining interest and attention from scholars around the world as a convenient and effective way of micro urban regeneration. As it is driven by the desire of residents to transform their own environment, pop-up practices have a catalytic effect on urban vitality that is accessible and sustainable in the long term. In China, bottom-up regeneration methods similar to pop-up urbanism have also been the focus of Chinese scholars in recent years. This study attempts to propose a new perspective on regeneration by researching pop-up urbanism in order to complement existing bottom-up regeneration theories. This paper first discusses and analyzes the origin and theoretical development of the concept related to flash urbanism. Through a fundamental theoretical study, it is found that there is a lack of existing theories on open space systems. Therefore, an innovative concept is proposed, that is, the public open space regeneration from the perspective of pop-up urbanism. Next, this paper analyzes the past pop-up practices and derives the spatial demands corresponding to different types of pop-ups. This demand can be further divided and summarized into a more general public open space regeneration methodology. Finally, in order to clarify the practical application model of the methodology, this paper identifies and evaluates the feasibility of Liuyun Community as a renovation object. The public space in the open community is a highly representative and implementable application scenario. After determining the compatibility between theory and practice, this paper applies the theory to the actual urban environment by combining the current situation, in an attempt to inspire future renovation actions in similar aspects. Overall, this research uses the perspective of pop-up urbanism as an entry point to propose an innovative urban regeneration approach in order to complement the existing academic system. The study follows the logic of "Theory - Case Study - Methodology - Practical Application" to support the full potential of bottom-up urban regeneration. Compared to the mainstream bottom-up regeneration concept in China, the trialability brought by the pop-up perspective makes regeneration projects more acceptable to stakeholders and easier to be implemented.
