Public service facilities are the important carrier of urban social service. The space coordinate configuration of public service facilities space and living space is of great significance to enhance the level of urban human settlements environment, eliminate social isolation, and maintain social harmony. Based on Google, Baidu, Tencent and other electronic maps which include the locations of 790 residential areas, 178 primary schools, 301 community hospitals, 1681 bus stops and other data which belong to Changchun city. This paper makes a quantitative analysis of the morphological characteristics, agglomeration characteristics and proximity relation of public service facilities space and living space, by using some software and some quantitative methods, such as ArcGIS 10.0, Kernel density estimation, Nearest Neighbor Indicator, Riley's K function, and location quotient analysis. The results showed that: (1) There is a significant difference in the distribution of public service facilities and living space, but a high correlation is found. There exist convergence and differentiation in the number of "core-periphery" distribution characteristics at the same time. In particular, the dislocation between primary school and living space is obvious. (2) There is a feature of space agglomeration between the public service facilities space and living space, but the differences in agglomeration scale and intensity are significant and the coordination degree of spatial distribution still need to be improved. (3) From the spatial relationship between the distribution of public service facilities and residential space, CLQ residential areas→community hospitals, CLQ residential areas→primary schools, and CLQ residential areas→bus stops values are 1.210, 1.176 and 1.133, respectively. Public service facilities have an obvious attraction for residential areas; on the contrary, it is not obvious, and the spatial pattern presented "asymmetry" characteristics. This paper argues that the coordination of public service facilities space and residential space, evacuation of public service facilities in urban core areas, and expansion of urban residential space under the guidance of public service facilities are an important path for future regulation to promote the coordination of public service facilities space and living space.
