以habitat 67项目和加拉加斯城市形态等的分形现象为例,研究以长方体单元的积聚作为基本生成法则的分形原则在跨越尺度的建筑和城市设计中的运用。抽象的长方单元体作为分形子整体同时具有整体和局部的特征,以分形几何的自我相似原则作为基础,子整体理论从形态学的角度为跨尺度的建筑和城市设计研究提供了一种互为关联的认识论和方法论。 Taking the habitat 67 project and the fractal phenomenon of Caracas city morphology as an example, this paper studies the application of the fractal principle of cuboid unit accumulation as the basic generating rule in the cross-scale building and urban design. As an integral part of the fractal, the abstract rectangular unit has both global and local features. Based on the principle of self-similarity of fractal geometry, sub-overall theory provides a kind of inter-scale architectural and urban design research from the perspective of morphology Epistemology and methodology for relevance.
