基于视域理论的广场空间围合性分析--以上海人民广场为例

Analysis on the Enclosure of Square Space Based on Visual Field Theory:A Case of the People’s Square of Shanghai

本文以界面与空间的围合性为缘起,以地面深度与界面高度的比值为理论基础,以上海人民广场为研究案例,通过分析空间特征和提取变量,发现了人民广场空间由于过于空旷和界面不连续,通过北侧界面和人行步道仅在中心区域形成了一定的围合性的问题,进而提出假设,并以3D建模模拟空间场景和依次提取空间切片模拟行进中心理感受变化的方法,验证了这一假设。

This paper starts from the enclosure of the boundary and space,takes the ratio of ground depth to interface height as the theoretical basis,and takes Shanghai People’s Square as the research case.By analyzing the spatial characteristics and extracting variables,it is found that the space of the People’s Square is too open and the interface is discontinuous,which only forms a certain enclosure in the central area through the north interface and pedestrian walkway,and then puts forward a hypothesis,which is verified by the method of 3D modeling to simulate the space scene and extracting space slices in turn to simulate the changes in psychological feelings.
