摘　　要：在开发相关的GIS应用系统时,常以GIS为中心,不分用户的需求层次,将用户原有数据库管理的数据全盘纳入到GIS的管理之中。但由于许多GIS软件的数据库管理功能比较薄弱,难以胜任原本可以由一般数据库管理系统完成的任务,为系统的开发带来不必要的困难;另一方面,全部数据纳入到GIS的管理之中,真正可利用的GIS功能却非常有限。针对这一问题,在分析用户需求类型的基础上,结合管理信息系统与GIS各自的优势,提出GIS应用系统的3种开发模式;并通过实例介绍了该类应用系统开发过程中的关键技术。When relevant GIS application system was developed,GIS has always been as centre,the layer of users’requirements was always been ignored,and all the data saved in database of users was brought into GIS.However,many GIS software is too weak to be competent at the complete assignment of database management system.In this case,an unnecessary difficulty was brought for development of system.On the other side,GIS application is limited when all the data were brought into GIS management.In view of existing problem and on analysis of type of users’requirements,the advantage of both information management system and GIS was combined in this paper and three development models of GIS application system were proposed.Moreover,the key technology in this kind of application system was introduced by real cases.
