备注

街道的视觉空间体验随游览路径和视点的方位动态变化,传统D/H理论在揭示此类空间属性时尚显不足.本文运用视域(Isovist )分析理论,结合Rhino + Grasshopper参数化建模、MATLAB可视化表达,从视野大小、锯齿度、视深、神秘性和游离度等5个方面对武汉楚河汉街主街空间序列进行了量化分析,总结了其设计的优缺点,并为研究城市街道的空间序列变化、动态空间体验和优化空间结构提供借鉴.

The visual space experience of the street changes dynamically with the visiting path and the orientation of the viewpoint.The traditional D/H theory is insufficient in revealing the attributes of this kind of space.In this paper, Isovist analysis theory,Rhino+Grasshopper parametric modeling and visualization in MATLAB are used to conduct quantitative analysis of the main street of Chuhe Han street in Wuhan from Isovist area,jaggedness,isovist diameter,occlusivity and drift.This paper summarizesd the advantages and disadvantages of the design,and provides reference for the study of changes in spatial sequence,dynamic spatial experience and optimization of spatial structure of urban streets.
