| 摘 要： | 探讨从地理空间认知出发，实现基于场所的GIS（PB—GIS）的相关问题。PB—GIS以场所为核心，显式表达地理空间知识，并遵循特定规则进行定性空间推理，从而服务于空间行为决策。比较PB—GIS与基于坐标的GIS（CB—GIS）之间的差异和适合解决的问题，并描述定性空间推理的特点及其在PB—GIS中的应用。在分析实现PB—GIS的关键技术基础上，采用三层架构设计了一个PB-GIS的概念体系结构。

| Abstract: | Place-based GIS(PB-GIS),which are different from the conventional coordinate-based GIS(CB-GIS),is discussed.Rooting in spatial cognition,with the manner of explicit representation of geo-spatial knowledge,place-based geographic information systems support spatial decision well.To implement a place-based GIS,spatial reasoning is its foundation function.Meanwhile,input knowledge,context,spatial relations,and reasoning rules are essential to qualitative spatial reasoning.In this paper,the applications and comparison with CB-GIS are also described.At last,based on the analysis of key components in PB-GIS,a 3-layed software conceptual architecture of PB-GIS is given. |
