【摘要】：研究一天中不同时段的城市活跃度及其稳定性可以为公共基础设施和公共服务设施的空间配置以及公共交通及安全政策的制定提供依据。本文通过出租车GPS数据所表现出的城市活跃度及其稳定性来研究城市的时空间结构形态。研究结果表明:城市活跃度的空间格局呈现出明显的中心外围结构特征,可以视为一种不规则的同心圆模式。不同日期在相同时段内城市活跃度的空间格局也存在差异,一些区域在星期一是城市活跃度一般,而同一时段的星期天城市活跃度较高。从城市活跃度和稳定性的节律特征来看,城市活跃度和稳定性均表现出明显的高峰与低谷,显示城市活跃度具有明显的日常活动的节律性。
[Abstract]:The study of urban activity and its stability in different periods of the day can provide the basis for the spatial allocation of public infrastructure and public service facilities as well as the formulation of public transport and safety policies. Based on the urban activity and stability of taxi GPS data, this paper studies the temporal spatial structure of a city. The results show that the spatial pattern of urban activity shows obvious characteristics of central and peripheral structure and can be regarded as an irregular concentric circle model. The spatial pattern of urban activity is also different in the same period of time. Some regions have average urban activity on Monday, but higher urban activity on Sunday at the same time. According to the rhythmic characteristics of urban activity and stability, urban activity and stability show obvious peaks and valleys, indicating that urban activity has obvious rhythm of daily activities.
