The invention relates to a multi-version GIS slicing service system which comprises a file storage server, an application cache server, a slicing server and a client, wherein the file storage server is used for storing slicing associated files in layers according to types and versions, wherein the slicing associated files include a slicing data file, a slicing resource description file and a slicing index file, the slicing data file is used for storing slicing data information, the slicing resource description file is used for describing the type, grade, coordinate and version information of the slicing data, and the slicing index file is used for describing the index information of the slicing data; the application cache server is used for loading the slicing index information into the application cache server; the slicing server is provided with an access interface capable of receiving a slicing request and is used for receiving a slicing request of the client, acquiring the corresponding slicing index information and slicing data and returning the corresponding slicing index information and slicing data to the client; the client is used for sending the slicing request and receiving the returned slicing data. The system is capable of providing access and management for multiple versions of GIS slicing, and is simple in system structure and good in use effect.
