| 摘 要： | 地理信息分类体系划分是否合理直接影响地理信息交互与共享。以国家基础地理信息陆地水系（GB/T 13923-2006）分类标准为例，借助地理要素的元概念特性抽取要素描述语义，利用形式化分析方法获取形式概念表及概念格Hasse图，通过格-树转化的方法，得到具有直接包含关系的陆地水系层次分类。该方法消除了原有分类系统当中存在的概念重叠与语义交叉，是对现有分类方法的一种有益补充。

| Abstract: | The reasonableness of the geographic information categorization system has a direct impact on the interaction and sharing of geographic information. A method is proposed to explore the hierarchical semantic categorization of the fundamental geographic information from GB/T 13923-2006 in China. First，we selected a set of meta-properties to extract the semantic of geographical entity, and then construct the formal concept context and Hasse Diagram based on Formal Concept Analysis, finally, we implemented Lattice-tree transforming method of generating the hierarchical semantic classification of hydrological domain, which possessed the direct semantic inclusion. The method eliminates the overlapping concept and crossing semantic among the original classification system, which is a useful complement to the existing classification methods. As well as merits and limitations are discussed. |
