城市肌理形态在城市形态中起着重要的作用，它不仅表达了城市的整体形态特征，而且描述了建筑与地块之间的关系，也就是模式。形态研究大多集中在街道网络形态、情节形态、建筑形态或类型等方面。另一方面，城市肌理的形态也反映了城市的空间特征，如街道的空间轮廓、视觉多样性、空间类型等，这些都直接关系到城市空间的质量。虽然这些特征影响着城市设计决策，但目前的研究还没有达到有效的水平。本文特别关注城市设计的潜力，提出了建筑位置对街道空间格局的影响。基于地理信息系统中的视域分析，可以测量城市结构形态与街道视域格局之间的差异。研究样本取自欧美、中国等不同城市的600平方米城市面料形象样本。提出了一种新的街道空间关联线(SSRL)模式。视域模拟结果表明，SSRL格局与街道空间形态之间存在着较强的相关性，视觉统计图能够反映出街道的空间特征。
The form of the urban fabric plays an important role in urban morphology which not only expresses the city's overall morphological features, but also describes the relationships between buildings and plots, which are called patterns. The majority of morphological studies have focused on the street network pattern, the plot pattern and the building pattern or typology. In the other hand, the form of the urban fabric also reflects the city's space character, such as street spatial outline, visual variety, and spatial typologies, which are directly related to the quality of urban space. Although these characters influence the urban design decision-taking, the current research has not reached an effective level. With a special focus on potentials for urban design, this paper proposes an account of how building position affects the street spatial pattern. Based on the viewshed analysis in GIS, the variance between the form of the urban fabric and the street viewshed pattern could be measured. The study samples were 600 meters square samples of urban fabric image selected from different cities of Europe, America, and China. This paper proposes a new kind of pattern: street spatial related line (SSRL) pattern. Through viewshed simulating it shows that there is a strong relationship between SSRL pattern and street spatial configuration, and that visual statistical diagrams could indicate the street spatial characters.
