摘要
基于热力图与兴趣点(POI)等位置服务(LBS)数据,应用核密度分析方法与地理加权回归模型对北京市六环内区域城市活力的时空特征与影响因素进行分析。结果表明:(1)城市活力的时效性明显,以24 h为周期呈下降、上升和波动变化趋势,周末的活力强度低于工作日;(2)活力现状空间分布不平衡,从城市中心向郊区递减,北强南弱,东强西弱;(3)街道常住人口密度、路网密度和POI面密度与城市活力呈显著正相关,人口密度、路网密度和POI面密度越高,则城市活力度就越高。
In this paper, Kernel density analysis method and geographically weighted regression model are used to study time-spatial characteristics and influencing factors of urban vitality within the 6th ring road of Beijing based on heat map data and point of interest （POI） data. The results show： （1） The timeliness of urban vitality is obvious, with the cycle of decline, rise and fluctuation in 24 hours; the vitality of weekends is lower than that of working days; （2） The spatial distribution of vitality is unbalanced; urban vitality weakened from center to periphery, from north to south, from east to west; （3） The population density, road network density and POI surface density have a significant impact on urban vitality, high density population, road network and POI will lead to higher urban vitality.
