Influence of Visual Proportion of Urban Street Cultural Landscape on Crowd Aggregation -- An Empirical Study on Street Space in Downtown Chengdu

摘要

This paper explored the correlation between the visual proportion of urban street cultural landscape and crowd aggregation. In the study, the relevant theoretical assumptions and measurement scales were established first; Then the street panoramic images of 535 sampling points were obtained through systematic sampling and field shooting; Easygo and POI (Points of Interest) data of the research area collected every two hours within one week were picked up through big data capture; Finally, the driving force of geographical differentiation was detected by using the geographic detector. The results showed that: (1) in the artificial landscape, the visual proportion of architectural landscape had a significant impact on crowd aggregation and the explanatory power q was 0.15. Neither the visual proportion of roadway landscape nor that of sidewalk landscape had significant impact on crowd aggregation; (2) In the natural landscape, both the visual proportion of greenery landscape and that of sky landscape had significant impact on crowd aggregation and the explanatory power q was 0.09 and 0.05 respectively; (3) The interaction between the visual proportion of architectural landscape and that of greenery landscape or between the former and that of sky landscape showed a two-factor enhancement and the interaction between the visual proportion of greenery landscape and that of sky landscape showed non-linear enhancement; (4) There were significant two-factor enhancement effects in the interactions among the the visual proportion of architectural landscape, that of greenery landscape, of sky landscape and aggregation of POI facilities, of which the biggest q value was 0.76.
