地缘体概念内涵及特征研究

地缘理论是在地缘政治、地缘经济、地缘文化、地缘科技等研究领域基础上构建的基础理论。地缘体是地缘问题的研究对象，是地缘理论研究的核心内容。论文在综合分析各地缘研究领域基础上，提出并明确了地缘体的概念与内涵，初步建立了地缘体类型体系，分析了地缘体空间、属性和时间等特征，并对地缘体的空间拓扑关系进行了简要描述，为地缘理论的建立奠定了基础。

Research on Attribute and Concept of Geo-Entity

At the turn of the century, the research content of the world patternbecame much richer. Consequently, geo-economics, geo-culture, geo-resources,geo-technologic, and other related areas appeared accordingly. Researchin these areas needs the geoborder theory as a guide. One of the corecontents of the geoborder theory is to generalize, and summarize geo-entity,which is the object of study, This paper defined and summerized the geo-entitytypes from three points of view： spatial scale, geometrical morphology andattributive characteristics, thereby built the geo-entity type system. Meanwhile,the division of specific types were described in details by using politicalgeo-entity, economical geo-entity and cultural geo-entity as examples.Different geo-entity has its own characteristics and rules, which reflectsthe basis of their properties and qualities. This paper mainly analysed politicalgeo-entity, economical geo-entity, cultural geo-entity etc. The spatialfeature of geo-entity decides the spatial relationships between differentgeo-entities. Distance and topological relations were described briefly inthis paper, furthermore, four different spatial relations （disjoint, adjoin,intersect and include） were deeply discussed to find out their reflections ofgeographical function intensity. This paper studied and analyzed the definition,types, characteristics and spatial relations of geo-entity, to lay thefoundation of building geoborder theory.
