摘　　要：地理信息要素分类体系搭建了地理概念之间的分类关系,但也割裂了要素之间的其他语义关系,如依赖、依附等关系。已有研究主要对地理概念间的相似关系进行了测度,但忽略了特有的地理信息语义关系。为了弥补这一不足,本文以国家基础地理要素分类体系为概念域,从行政、隶属、空间形态等方面对地理概念的语义关系进行筛选和显式定义,并设计了用于语义关系推理的核心算子,为地理要素的多元语义关系重构提供了基础。最后实例验证了算法的有效性。Geographic features classification system constructs the classification relationship between geographical concepts, but separates other semantic relationships between features, such as dependency and attachment, etc. The existing researches mainly measure the similarities between geographical concepts, but neglect the unique geo-semantic relations. In order to make up for the deficiency, this paper selects and explicitly defnes the semantic relations of geographical concepts in terms of administration, subordination and spatial form, based on the classifcation system of national basic geographical features. At the same time, we design the core operators for semantic relation reasoning, which provide the basis for the reconstruction of the multiple semantic relations of geographic features. At last, an example verifes the efectiveness of the proposed algorithm.
