城市物质空间更新是城市发展的自然历史过程。转型期的中国城市,物质空间更新的速度与范围正在逐渐加大,且深度作用于社会经济空间重构过程。本文首先全面总结了国内外城市物质空间更新的相关理论与研究成果,凝练了在城市物质空间更新背景、演替脉络、更新模式及策略方面的核心思想与评判方法,总结了城市物质空间更新的成功做法和经验。其次,从城市物质空间更新的空间判定与时空组织模式、建筑资产拆损、更新模式与综合评估、影响因素与机制定量研究方面对中国未来的城市物质空间更新研究进行了展望。最后,本文认为在新型城镇化和资源节约型社会建设大背景下,有必要加强中国城市物质空间更新的系统研究、综合研究、动态研究和定量研究,进而为制定因地制宜的物质空间更新优化调控政策和方案提供依据。
Urban physical space upgrading is a natural historical process of urban development. Upgrading urban physical space is an inevitable and common practice. In Chinese cities that undergo great transition, the extent and scope of development in inner cities are gradually increasing, which have important implications for the restructuring of the socioeconomic aspects of cities. This article first presents a comprehensive summary of the theories and research on the upgrading of urban physical space within China and internationally, extracts core ideas and evaluation methods concerning the background, succession, models, and strategies for urban physical space upgrading, and summarizes the successful practices and experiences of urban physical space upgrading.Second, the article examines the prospects of research on urban physical space upgrading in China with respect to the determination and spatiotemporal organization, building assets demolition losses, upgrading model and comprehensive assessment, influencing factors, and quantitative research mechanisms. Finally, the paper argues that under the background of new urbanization and developing a resource-saving society, it is necessary to strengthen the systematic, comprehensive, dynamic, and quantitative research of Chinese urban physical space upgrading in order to provide a basis for the optimization of control policies and plans that take into consideration local conditions.
