基于空间连续性测度的街道可识别性提升机制研究

Study on the Mechanism of Street Recognizability Enhancement based on Spatial Continuity Measure

在街道设计中,哪些街道要素宜连续有序,哪些街道要素宜独具特色,弄清这些问题的答案对厘清街道可识别性的提升机制尤为重要。文章以杭州七条现代商业街道为例,通过对街道要素的连续性测度,探究街道连续性与可识别性的关联关系,揭示提升街道可识别性的街道要素组织特征。研究得出:断面类别复杂度、断面类别差异度、行道树及相关绿化连续度对街道可识别性有较显著的正相关影响;路灯、广告牌、垃圾箱、人行流线通畅度对可识别性有较显著的负相关影响。

In street design,the question of which street element should be continuous or which street element should be unique is particularly important to clarify the mechanism of street identifiability improvement.Taking seven modern commercial streets in Hangzhou as an example,this paper,by measuring the continuity of street elements,explores the relationship between street continuity and street identifiability,and reveals the organizational characteristics of street elements to improve street identifiability.It shows that the complexity of section category,the difference of section category,the continuity of street trees and related greening have a significant positive correlation on the street identifiability,and the continuity of street lamps,billboards,dustbins and pedestrian streamline patency have a significant negative correlation on the street identifiability.
