Abstract: With the rise of humanism and improvement of living standards, improving the quality of lives is now one of the hot topics, which is also the foremost purpose of Time Geography. The using of T-GIS helps to meet the needs of Time Geography, with a strong requirement of representing the temporal and spatial relations. Based on the theories of T-GIS and Time Geography, the household survey is conducted on people's daily activities and travel logs in Guangzhou, China. A series of functions for recording and representing the spatio-temporal pattern for daily activities and travel chains is developed by VBA secondary development platform of ArcGIS. It is shown that urban center in inner cities is still attractive, which lure a lot of people during the whole day. Residents, especially those who live in suburban areas have to change their daily activity pattern to adapt to the sprawl of the city. The spatio-temporal patterns of residents' activities are different among people who come from different classes. on this basis, three classes are divided. The activity space of lower class is smaller, mostly concentrated in inner city and the area around their residential communities, and their payment for transportation is the lowest. But the activity space of upper class is larger, and most of the activity space is around new center of the city, Their time spending on outdoor activities is well-regulated, and their payment for transportation is the highest. There is a close relationship between resident behavior and urban internal spatial structure, which will provide a reliable basis for urban planning and urban management.
