摘　　要：由于人类认知差异和语义描述的模糊性,导致地理要素语义表达的不一致以及信息共享的极大困难。鉴于本体是解决基于语义知识表达的有效方法,该文以黄土地貌为例,使用本体的形式化定义形式,对黄土地貌概念进行语义形式化表达,提出了构建黄土地貌的五元组逻辑结构,进而建立了黄土地貌的本体模型。Due to the difference in human cognition and the ambiguity in semantic description,it leads to inconsistency in semantic representation of geographical features and further great difficulties in multi-sources information integration and sharing.It is well known that ontology is an effective method of knowledge representation to solve problems on semantic inconsistency.Therefore formal ontology is employed to represent loess geomorphology in this paper.Formal semantic representation about the concept of loess geomorphology is made by using formal definition method of ontology.Then the logic structure of the loess geomorphology ontology is proposed according to the properties of loess geomorphology.On this basis,the ontology model of loess geomorphology is built.
