Community life circle examines urban communities from the perspective of residents' daily activities. It is the frontier of urban geography and urban related studies. It is also an important part of the innovation of Chinese territorial and spatial planning system and an important starting point for the sustainable development of China's urban society. With the continuous deepening of mobility and informatization, the agents of community life circles, community activities and residents' spatiotemporal behavior, and the function and meanings of community space are becoming more diversified, which needs innovative research and practical guidance of urban social geography. Time-geography is a comprehensive social-technical-ecological approach to understand the relationship between humans and the environment, which provides an essential basis for early research on community life circles based on activity space. New time-geography attaches great importance to the interactions and spatiotemporal combinations of projects between family and other social organizations. It can provide an important basis for the study of the complex interactions between individual, family, and community and the sociocultural constraints, the complex context analysis, and the simulation of spatiotemporal behavior in community life circles. Based on the new time-geography approach, this study proposed a new time-geography research framework of community life circle from theoretical, methodological, and empirical perspectives, including: 1) constructing the community life circle theory based on spatiotemporal behavior and revealing community life circle spatial and temporal structures; 2) developing methods for collecting and analyzing spatiotemporal behavioral data of community life circle and simulation; 3) innovating Chinese urban planning and management from the aspects of optimizing residents spatiotemporal behaviors within the community life circle, community social interaction life circle, and community safety life circle.
