Abstract: In the domain of GIS，spatial data are frequently brought out to field or other data-collecting spot to update，this is called disconnected editing.Combined with the concept of MAPGIS7.0 version，a geographical-database version driven disconnected editing method is brought forward，the realization method is discussed with emphasis，and the key algorithm and points are also given.The strategy has been successfully implemented in MAPGIS7.0，and proved to be viable and right，and can satisfy the need of practical application of GIS remote working or field editing.

摘要： 在GIS行业，大量数据需要频繁地带到野外或其它数据采集现场进行更新，即离线编辑。结合MAPGIS7.0版本管理，提出了一种地理数据库版本驱动的离线编辑实现方法，详细阐述了其实现策略，并给出了实现的关键算法和注意要点。该方法已经被MAPGIS7.0平台采纳，实现了地理数据库的离线编辑功能，能够满足GIS远程或野外作业对离线编辑的实际需求，证明了该机制的正确性和可行性。
