摘　　要：AM/FM/GIS系统建设中,基于几何空间与基于逻辑空间的对象进行统一管理是核心问题。提出空间对象模型的概念,并给出严格的形式化定义。通过对AM/FM/GIS数据模型的分析,运用面向对象的AM/FM/GIS数据建模方法,实现了信息基础设施中的数据存储与管理,提高了AM/FM/GIS系统的运行效率。When constructing AM/FM/GIS systems,the core issue is to uniformly manage the geometry spatial-based and logic spatial-based objects.This paper presents the concept of spatial object model and the strict formalized definition is brought forth as well.By analyzing the data model of AM/FM/GIS and adopting object-oriented AM/FM/GIS data modelling method,the data storage and management in information infrastructure have been realized,which improves the running efficiency of AM/FM/GIS system.
