城市街道景观视觉与情感感知的关联机制OA

Urban streetscape perception serves as a critical indicator for evaluating the quality of street space.The existing research has predominantly focused on either visual perception or emotional perception as singular dimensions,leaving the association mechanism between them inadequately understood.This paper aims to systematically quantify the correlation mechanism between visual perception indicators(green view index,openness,enclosure,and image quality)and emotional perception indicators(perceived safety,vitality,aesthetics,affuence,depression,and boredom).This paper selects three cities of Guangzhou,Shenzhen,and Haikou,and carries out correlation analysis based on the semantic segmentation data derived from 116 353 street view images.It is found tha t ①there is significant correlation between visual and emotional indicators(P<0.01),with correlation coeffcients ranging from-0.379～0.439.②Green view index exhibits positive correlations with positive emotions and negative correlations with negative emotions.③The effects of openness and enclosure demonstrate significant city-specific variations,reflecting the moderating role of urban morphology and culture.④The correlation between image quality and aesthetics in Shenzhen(r=0.070)is significantly higher than that in other cities,highlighting the importance of design quality.This paper provides systematic empirical evidence for the relationship between visual and emotional perception within the Chinese urban context,reveals the differential characteristics of perception mechanisms across cities,and offers a scientific basis for localized streetscape evaluation and design optimization.
