Taking the downtown area of Jiangmen as the research object, based on the POI data, with the help of the grading of service facilities and the concept of service radius, an index evaluation system for the convenience of urban residents’ life is constructed. Through the analysis results, the following conclusions can be drawn: The convenience index value of the residents in the downtown area of Jiangmen is not high, and the gap between urban and rural areas is large. The spatial differentiation is obvious, and regional services in peripheral towns and villages are relatively isolated; there is a certain correlation between the convenience of residents' living and the spatial distribution of construction land, but the construction of service capacity in key areas is slightly lagging behind. In response to the urban situation of Jiangmen City, the following suggestions are put forward for the follow-up planning: effectively improve the city’s public service capabilities and strengthen the overall level of the city; rationally connect the peripheral areas to further form the urban agglomeration development pattern; accelerate the infrastructure construction in key areas, Cooperate with the development strategy of the city.
