Reasonable matching of workplace and residence space is a difficult problem that urban researchers have been focusing on for a long time， and suburbs are one of the most prominent regional spaces for matching the workplace and residence. In-depth research on the characteristics of workplace and residence space in the suburbs is an important way to explore the spatial relationship of urban and rural functions. It is of great significance for resolving the contradiction of the dual structure of urban and rural areas and realizing the overall development of urban and rural areas. This article focuses on the suburbs of Hefei City， uses cell phone signaling data covering the whole city area to identify suburban working and residential populations， and develops a visual analysis of the distribution pattern and characteristics of the workplace and residence space in suburbs， and then uses the jobs-housing self-containment index， jobs-housing balance index and spatial mismatch index to analyze the reasonable degree of matching of suburban workplace and residence space under different spatial scales， and discusses the relationship between the workplace and residence space in the suburbs and the central areas of Hefei City. Results of qualitative and quantitative analyses showed that the suburbs of Hefei City were dominated by residential functions， and the spatial distribution of the workplace and residence space was generally uneven. Only a few towns in remote suburban had a high degree of integrating the space of workplace and residence. Most of the suburban townships and streets did not match the functions of workplace and residence， and the central area and the suburbs had a complementary relationship in spatial function. In the future， it is still necessary to further combine multi-source data to explore scientific factors affecting the distribution of the workplace and residence space in suburban areas and methods for optimizing spatial layout.
