睹始知终 方能完善发展——城市设计中的图层思想溯源

梳理和整合城市要素以及各个要素和图层之间的关系,可以清晰地看出其对于城市物质空间的影响。城市设计中的图层思想出现于“图底关系”理论时期,并在分形学、类型学、符号学等理论的基础上得到了发展。基于已有的理论及研究,分别从城市物质空间、生态景观和抽象空间3个视角,系统地梳理了城市设计理论与方法中图层思想的起源及发展脉络,以探索在此基础上应该如何形成较为完善的城市设计图层理论。

KNOWING THE END FROM THE BEGINNING: THE TRACEABILITY OF LAYER THOUGHTS IN URBAN DESIGN

This paper summarizes urban elements and relations between each element and the urban layer,from which the effects of the relations on urban physical space can be seen clearly.The layer thoughts in urban design first appeared in the "figure-ground relation" theory period,and developed on the basis of the fractal theory,typology,semiology,and so on.Based on the existing theories and previous studies,the paper systematically reviews the origin and the development of the layer thoughts in urban design theories and methods from three aspects:urban physical space,ecological landscape,and abstract space.It suggests further exploring how to form the urban layer theory of urban design.
