Multi-dimensional perception of urban environment and their relationship with urban functional characteristics

Urban perception research is essential due to the rising demand for high-quality urban spaces, but current research often overlooks the spatial heterogeneity and functional characteristics of urban environments. This study aims efficiently evaluate urban environment perception based on street view images, and couple urban spatial structure with functional characteristics to understand impact mechanisms. We associate street scene images with visual elements to evaluate urban environment perception across six dimensions, with a case in Changchun, China. Various index factors of functional characteristics are introduced to explore the influence mechanism of urban environmental perception. This research enriches the theoretical framework of urban environmental perception and provides technical support for comprehensively evaluating urban spatial quality, considering influencing factors related to the physical environment and social functions.
