摘要
讨论了ＧＩＳ（ＧｅｏｇｒａｐｈｉｃＩｎｆｏｒｍａｔｉｏｎＳｙｓｔｅｍ）的概念模型，提出了多库互操作和构架基概念；对ＧＩＳ概念模型的几个基本问题：ＧＩＳ的本体结构，地理信息驮载下的属性信息表达，综合地理信息的互操作和ＧＩＳ的构架基模型进行了较充分的阐述。
The conceptual model system of GIS(Geographic Information System) was discussed, which includes the analysis, investigation and resolvents of GIS conceptual constructure and its inner mechanism such as the fundamental constructure of GIS, information expression of 3 d geographical space, inter operation of Multi Bases management and the architecture base of GIS and so on. Three new types of conceptual model system of GIS were produced.
