The invention discloses a data consistency and wear leveling-based memory file system management method. A persistent memory file system is subjected to data consistency and writing wear leveling at the same time in data updating operation, and file updating operations include three updating modes of file on-site updating, appending and partial appending. The data consistency of the memory file system is cooperatively realized through three modules of metadata management, data consistency and log management, and the file updating operations. A nonvolatile storage management function is cooperatively realized through three modules of page allocation, idle page management and wear leveling, and the file updating operations. A wear leveling function is cooperatively realized by two sub-modules of data area page writing frequency management and indexing, and other modules in storage management, so that all the file updating operations are subjected to writing wear leveling while data consistency updating is realized.
