Research on Urban Public Service Equalization on the Basis of GIS: Take the Main Urban Districts of Nanchang City as an Example

This paper, with the help of GIS, aims to build a spatial data model which includes the top three hospitals, education facilities and parks. By the buffer analysis and overlay analysis of the time cost of the passage, education facilities of primary and secondary schools as well as several park services, this paper tries to discuss the characters of their spatial arrangement. Meanwhile, taking the main urban areas of Nanchang City as example, following conclusions can firmly be drawn: (a) Public service scope is mainly around the old town, which is overlaying seriously. (b) Due to the shortage of park resources in Nanchang City, the service scope is quite limited. (c) Districts, like north of the Qingshanhu district and Honggutan district, are lack of public service, which has caused the inequality of the public service. This paper provides some reference for the planning of public resource and old town.
