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。 Researching active level and its stability could help policy making in spatial allocation of public infrastructure and public service facilities as well as public transportation safety. Traditional public service facilities and infrastructure allocation has limitation as it is based on static population distribution rather than considering individual mobility. It is important to get city active level information, but it is not easy to collect relative data as traditional census does not involve temporal information. However big data（taxi GPS e.g.） provides a new data collection approach in this field. Taxi GPS trajectories have advantages in massive data, flexibility and dynamics compared to travel diary, publication transportation data and land-use data, etc. Taxi travel takes a proportion of 14.78% in citizen daily travel. This study explores urban spatial temporal structure of active level and stability represented by GPS trajectory data. Main results are as follows. Characteristics of spatial pattern of urban activity has obvious center periphery structure, can be regarded as a kind of irregular concentric patterns. Differences also exist in different date. Active level in some areas is higher in Sunday than Monday in the same time period. From perspectives of active stability rhythms, active level and stability present obvious peak and trough over time. Urban active level has obvious daily rhythms feature.
