- Abstract
Urban vitality is an important manifestation of urban space quality, guiding the construction of sustainable cities・ We use mobile signaling data to explore the spatial distribution patterns of vitality of different age groups, and exploit the multiple linear stepwise regression and multiscale geographically weighted regression (MGWR) to quantify the impact of built environment on spatial-temporal heterogeneity of vitality of different age groups. The findings are as follows. 1) According to the differences of activity ability and demand of different age groups, the spatial distribution pattern of their vitality can be divided into lour types:ndetached core and compact Iormn ndetached core and extended form'T "gathered core and extended formn and "gathered core and compact formn・ 2) The impact of built environment on the group vitality shows significant difference in group category and spatiotemporal heterogeneity・ Location conditions generally affect the group vitality, and have stable time variation characteristics. About traffic accessibility, the influence of intersection density during the daytime is higher than night, which is conducive to the improvement of the vitality of youth and elderly・ The number of bus routes is positively correlated with the elderly vitality during daytime・ On building space, building density during the daytime has a higher positive impact on the vitality of teenagers and elderly groups than that at night The effect of floor area ratio on the night vitality of youth group and the daytime vitality of elderly group is opposite・ Compared with land-use mix, the density of specific supporting facilities has a more prominent impact on the group vitality. The research can provide reference for the precise design of the city and the layout ol differentiated facilities, so as to promote the coordinated development of urban space.
