城市空间形态分区的理论建构与实践探索

THEORETICAL CONSTRUCTION AND PRACTICAL EXPLORATION OF URBAN SPATIAL FORM PARTITION

中国城镇化进程的"降速-提质"转型对于空间形态的品质和特色提出了更高的要求,城市空间形态分区以街坊三维形态作为基本控制单元,为城市总体层面的空间形态优化提供理性化支撑,促进城市空间形态的优化,在调控城市建设中发挥更重要更有效的作用。本文在分析国内外理论实践的基础上,厘清了空间形态的逻辑体系,从空间内在机理入手,阐述其公益性、经济性和美学性的价值导向和城市空间表征,并剖析空间形态分区的控制要素,揭示了空间形态发展的内在机制,分析了空间形态分区的控制目标、工作内容和方法以及可能产生的作用,初步建构了空间形态分区的框架,进而提出了城市空间形态分区控制的方法体系,建立空间形态的结构骨架与外在意向的整体控制框架,从基于公益性的空间底线划定、基于经济性的基础模型和基于美学性的设计修正、基于操作性的控制管理等方面,探索城市空间形态分区的理论与方法。

Because of the ＂slower speed, higher quality＂ transformation during China＇s urbanization process, a higher demand was put forward for the quality and characteristics of spatial form. Therefore, urban spatial form partition took the three-dimension shape as the basic control unit, in order to provide rational support for urban spatial form optimization from the overall level, to promote the optimization of urban spatial form, and to play a more effective and more important role in the regulation of urban construction. This paper clarifies the logic system of spatial form based on the analysis of related theories and practices both at home and abroad, and expounds its public welfare, economic and aesthetic value orientation, as well as urban spatial representation from the perspective of the inherent spatial mechanism. Afterwards, the paper analyzes the control factors of spatial partition, reveals the inherent mechanism of spatial form development, and explores the control objective, content, and methods of urban spatial partition, as well as the possible effects. Accordingly, it develops a preliminary spatial partition framework, and puts forward the methodological system of urban spatial form partition control, the structural framework for building spatial form, and the general control framework for external intention. Overall, it explores the theories and methodologies of urban spatial form partition from the perspectives of the spatial bottom line delimitation based on public welfare, the basic model based on economy, the design amendment based on aesthetics, the control management based on operation, and so on.
