Abstract  The spatial and temporal behavior of the residents has become an important perspective of the perspective of urban space. This paper preliminarily explores the behavior space of residents and urban social space. This paper reveals the regularities of distribution of living space, employment space and consumption and leisure space roughly, and then we can understand the urban space from the perspective of the process and pattern of human-environment interaction. The provincial government and its surrounding areas become the regions with the highest utilization rate of space. The residents' activity space presents a typical circle structure. Taking the provincial government as the center, the population activity density is decreasing gradually. Population activities are characterized by concentration in the daytime and dispersion at night. Population activities are also concentrated in the working days and dispersed in the rest days. The paper finds that the dependence of residential activities on central urban area is very high, which is significantly higher than the employment activities and consumption and leisure activities. The lag of the development of the third industry leads to the lack of distinctions in the division of employment space. The employment activities present a multi center continuous development pattern. In addition to the traditional commercial center, the Eurasia shopping mall in the outskirts of the city and Jingyuetan forest park in the suburbs have become important choices for people to consume leisure activities. There are significant differences in the community of employment distance and consumption and leisure distance, which reflects the complexity of the three types of activities.
