摘要: It appears that the current research on the relationship between built environment and walking activities of the elderly hasn't considered the relationship between individual subjective perception and the spatial hierarchy. This paper develops a multi-level linear model of subjective perception, built environment and walking distance efficiency of the elderly to reveal the nature and degree of interaction among variables at all levels. The results show that: safety and mobility are two subjective factors affecting the walking efficiency of the elderly. The impact of built environment factors on elderly walking distance efficiency shows either consistency or difference. The intersection density, NDVI vegetation coefficient and public service facilities density are the consistency factors, while the plot ratio and road network density have different impacts on the travel distance of 300 meters or longer. The mediating effect test shows that the floor area ratio is the key factor relevant to the traffic safety within 300-meter walking space; the community open form affects the elderly's long-distance travel through the security of surrounding areas; NDVI vegetation coefficient is also an important factor related to the elderly's walking environment security.
