摘 要: 討論了GIS(Geographic Information System)的概念模型， 提出了多庫互操作和構(gòu)架基概念； 對GIS概念模型的幾個(gè)基本問題：GIS的本體結(jié)構(gòu)，地理信息馱載下的屬性信息表達(dá)，綜合地理信息的互操作和GIS的構(gòu)架基模型進(jìn)行了較充分的闡述， 給出了GIS的理論框架。

Abstract: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.
Key words: GIS conceptual model spatial information expression inter-operation of
Multi-Bases management architecture base of GIS
