街道界面密度与城市形态的规划控制

街道界面密度是用于表征街道界面围合程度的量化指标。通过分析城市实例,发现街道界面密度与街区建筑密度存在近似正相关关系,街区建筑密度与街廓尺度存在近似负相关关系。通过分析街道实例,发现街道的密度表征比尺度表征更为有效。结合分析我国主要大城市的商业步行街,认为小尺度街廓是形成优秀街道空间的必要条件。

STREET INTERFACE DENSITY AND PLANNING CONTROL OF URBAN FORM

Street Interface Density is the parameter used to describe the enclosing level of street interface.By analyzing example cities,this paper discovers that the Street Interface Density has an approximate positive correlation with District Building Coverage Ratio,and an approximate negative correlation with Block Scale.By analyzing example streets,the paper shows that density-index of street is more efficient than scale-index.And based on a study on the commercial pedestrian streets in main cities of China,the paper finds that small block scale is necessary for the formation of good streets space.
