摘要: 空间相似关系在空间目标的描述与匹配、空间数据库的查询与更新及空间认知和推理等方面被广泛应用,但由于其综合性和复杂性,其形式化描述和表达困难,可计算性偏弱,导致目前研究成果少而零散,未见成形的理论体系。为此,本文构建了空间相似关系的理论体系框架,在此基础上首先阐释了空间相似关系的定义、分类、性质与影响因子,然后论述了同尺度空间相似关系和多尺度空间相似关系的计算方法,进而探讨了空间相似关系的重要应用领域,最后给出了空间相似关系潜在的研究方向。本文成果是对空间关系理论的有益补充,有助于空间相似关系的未来研究更加严谨、深入和系统。

Abstract: Spatial similarity relation is widely used in description and matching of spatial objects, retrieval and renewal of spatial databases, and spatial recognition and spatial reasoning. However, there exist only few trivial achievements in spatial similarity relations, for spatial similarity relations are usually comprehensive and complex, and they cannot be described and expressed formally and cannot be calculated conveniently, either. Therefore no theoretical system of spatial similarity relations has been constructed by far. To fill the gap, this paper proposes a theoretical system for spatial similarity relations. Based on the system, this paper firstly presents the definition, classification systems, features and influence factors of spatial similarity relations, and then addresses the calculation methods of spatial similarity relations at the same scale space and different scale spaces, respectively. Further, it presents some applications of spatial similarity relations. Finally, it gives a number of potential research issues in spatial similarity relations. This work is a useful complementary of the theory of spatial relations and possibly makes the research in spatial similarity relations more rigorous, deeper and more systematic in future.

Key words: theoretical system, spatial similarity relation, spatial relation, same scale, multi-scale
