摘　　要：针对多尺度矢量地图数据库中空间关系的基础理论薄弱,而地图本质上是人们在不同尺度下认识地理实体后以大量模糊语言表达和描述,提出模糊相似关系概念,在地学信息图谱方法论的指导下,定量模糊相似关系的"谱"特征,提出多尺度矢量地图数据库中模糊相似关系的图谱构建技术体系和流程。本文的研究将有助于多源、多尺度矢量空间数据的集成与融合、变化检测与匹配等,从技术手段上提供了算法基础。According to the basic theory of spatial relations in the multi-scale vector map database,the essence of maps is that people express and describe maps by a large number of fuzzy languages after they recognize geographic entities at different scales,we put forward the concept of fuzzy similarity relation,according to the geo-informatics Tupu methodology,ration the feature of fuzzy similarity relation,put forward the technical system and process,that structuring Tupu of fuzzy similarity relation in the multi-scale vector map database.The research in this paper will be helpful to the integration and fusion of multi-source and multi-scale vector spatial data,the detection of change and data matching,at the same time,this research can provide much basics for the algorithm.
