From the perspective of residents'daily behavior,assessing the matching relationship between public service facilities and residents'needs is an important means of diagnosing the unreasonable layout of facilities within the living circle.Existing researches mainly start from a spatial perspective,without considering the dynamic changes in the time dimension.Based on the differences in residents'behaviors and activities,this study divides the time period,uses POI data and mobile phone signaling data to put forward an evaluation idea of behavior facility spatio-temporal matching degree oriented to the community life circle,and takes Nanjing central urban area as an example to conduct an empirical study.The results show that although the supply of facilities and residents'activities are significantly positively correlated in the spatial dimension,there are obvious spatio-temporal differences between the two and matching dislocation occurs in some time periods in the time dimension.The proposed method can not only evaluate the spatial match mode of facility layout and residents'activities,but also reflect the changes in the time dimension,and then more comprehensively identify the problems in the match of facility supply and demand,and support the strategies of spatio-temporal configuration of facilities and residents'activities guidance.
