基于视觉感受的街道空间量化研究--以合肥市一环内城区街道为例

Study on Quantization of Street Space Based on Visual Sense--A Case of the Streets in the First Ring Road of Hefei

随着城市化进程加快,老城区的街道形存而活力渐失。本文通过量化分析的方法,研究合肥市一环内城区的街道空间特征以及不同街景带来的视觉感受,以期为城市老街道的改造积累经验。采集所研究城区的街景图片,选取合适的图片作为研究对象,将图片内街道的构成要素进行量化解析,初步分析街道特征,并进行基于眼动实验的街景视觉兴趣点研究、视觉感受矩阵量表打分评价,最后将街道空间构成要素与眼动指标和视觉感受偏好评价得分进行曲线拟合,研究发现街道的绿化度、开阔度与视觉感受存在显著相关性。

With the acceleration of urbanization,the vitality of the streets in the old city is gradually lost.This article uses quantitative analysis methods,studies the spatial characteristics of streets in inner city of Hefei and the visual sense brought by different streetscape,taking this as an example,in order to accumulate experience for the reconstruction of old urban streets.The field survey was conducted and the streetscape pictures were collected,appropriate pictures were selected as the research objects.The components of the streets in the picture were analyzed quantitatively and the street characteristics were preliminarily analyzed.Then,the research on visual interest points of streetscape based on eye movement experiment and the scoring evaluation of visual sense matrix scale were carried out.Finally,the curve fitting of street space components,eye movement indicators and visual sense preference scores was conducted,and it was found that the greening and openness of streets were significantly correlated with visual sense.
