Focusing on the national fundamental geography information database, this article puts forward the construction of multi-level model in allusion to the status quo of the spatial data model, and defines the layered structure of multi-level model, thus reducing the strength and stress of building GIS spatial database. Besides, it also founds a mapset model mathematics basis, on which defines an extended space query language that is MapSQL which is communicating at all levels of model for data transfer and realizes the model of managing Mapset to reduce large amount of data space. Finally, the feasibility and practicality of the model of managing Mapset which is based on multi-level have been demonstrated by experiment.
