摘　　要：在全空间信息系统中，现实世界中的各类实体被抽象为多粒度时空对象，以实现对象的实例化，并通过建立“关联关系”来描述对象之间的联系，以保证在信息空间中构建与现实世界对应及关联的数据世界。本文分析了目前GIS中常用的关联关系，阐述了全空间信息系统下多粒度时空对象关联关系的概念与特点，提出了两种顾及其特点的关联关系描述方法，为下一步多粒度时空对象的建模提供了理论依据，同时为研究关联关系查询、分析及推理等问题打下了基础。In pan-spatial information system, muhi-granularity spatial-temporal objects are abstracted from entities in real world to instantiale independent objects. Associative relationship is established to describe connections between objects, so as to build a data worhl associated with the rea｜ one in information space. The commonly used associative relationships in GIS aree ana- lyzed in this paper, the concept and features of multi-granularity spatial-temporal objects associative relationship in pan-spatial in- formation system are elaborated, and two methods considering its fratures are proposed for associative relationship description. These methods provide a theoretieal foundation for muhi-granularity spatial-tempnral object modeling and a basis for future re-search on inquiry, analysis and reasoning of associative relationship.
