依托建筑中轴线对紫禁城的平面布局进行几何构型分析,包括圆形分析、三角形分析和长方形分析。在长方形分析中,分别以宽度与长度之比为0.783、0.535、0.663和0.837四种情况的长方形作为构型单元。通过作图分析发现:位于上述几何构型特征点上,均布置有建筑物或者建筑物的边线。这种基于几何拓扑关系的构型分析结果,在紫禁城的建筑布局中应该不是偶然性巧合。因此,有必要对蕴藏在古代建筑设计中的几何构型规则进行系统研究。
Centering on the building central axis the paper analyzes the geometry configuration of the plane layout of the Forbidden City, including the circular analysis, the triangle analysis and the rectangle analysis. Four rectangle configuration units with the ratio of width to length such as 0.783, 0.535, 0.663 and 0.837 are respectively studied. In the diagraph analysis, buildings or building edges are found to be located on the geometric feature points above. The result of the configuration analysis based on geometric topo-relationship is not an accidental coincidence in the architectural layout of the Forbidden City. Therefore, it is necessary to study systematically the geometry configuration rules in the ancient architectural design.
