Disclosed is a system for providing a moblog-based regional community service through a mobile terminal. The system includes a location-based community server for setting a plurality of main arenas by dividing a geographical area in a regional unit, setting and storing one or more virtual spatial locations, the one or more virtual spatial locations being a projection of real spatial public locations, as spots in one of the main arenas, receiving information on posts registered in spots transmitted through a mobile terminal by providing one or more pieces of information on the spots belonging to the main arena from information on a location of the mobile terminal to the mobile terminal, and storing the received information on posts with a link with the spots.
