上海主城区高架桥下空间治理研究

Space Governance Beneath Viaducts in the Central Urban Area of Shanghai

城市建设已经步入存量更新的高质量发展阶段,以上海主城区高架桥底部空间为例,重点盘活闲置空间、废弃空间、负面空间等点状小微空间。分析上海主城区高架桥底部空间的特点及潜在问题,结合国内外优秀案例研究,为高架桥底部空间的治理建设提出可行性建议。研究发现,高架桥底部空间受地理位置、规模大小、空间形态等因素的影响,存在空间功能及业态单一、立地条件差、地域文化缺失、权属混乱后续维护困难等问题。高架桥空间治理应综合考虑城市经济、社会和环境要素,从空间营造、文化传承、经济效益、生态效益、社会参与、责任归属等方面进行全生命周期的审视。

Urban construction has entered the stage of high-quality development in terms of stock renewal.Taking the space beneath the viaduct in the central urban area of Shanghai as an example,the work aims to revitalize the underutilized,abandoned,and negative spaces,as well as other small and micro-spaces.The characteristics and potential issues associated with the space beneath the viaduct in the central urban area of Shanghai are analyzed.Then,the feasible suggestions are proposed for its governance and construction by incorporating exemplary case studies from both Chinese and international contexts.It is observed that factors such as geographical location,scale,spatial form,etc.,influence the space beneath the viaduct while presenting challenges like limited space functionality and format diversity,unfavorable site conditions,absence of regional cultural elements,ownership ambiguity,and subsequent maintenance difficulties.Therefore,comprehensive consideration should be given to economic,social,and environmental factors during space governance while examining aspects such as space construction practices,cultural preservation,economic benefits,ecological advantages,social participation,and responsibility ownership throughout the entire life cycle.
