摘　　要：鉴于当前缺乏针对岛礁及其资源环境领域知识的建模,导致要素语义表达中的模糊性和差异性,难以满足相关空间数据组织与共享的需求。该文在深入分析岛礁及其资源环境相关领域知识的基础上,引入地理本体理论与方法,充分考虑各要素的概念与关系特征,通过定义类、属性、关系和约束条件,实现对要素概念及关系的形式化表达,以完成岛礁本体的构建;同时利用四叉树编码实现岛礁与空间数据间的映射关联,以支持岛礁空间数据的一体化集成与管理;最后分别以永兴岛与海浪数据为例说明该本体规范化表述,并以岛礁信息检索为例验证其有效性。结果表明该本体能较好表达岛礁及其资源环境要素的相关知识,具有一定的实用价值。For lack of knowledge modeling on islands and related resource environmental features in the South China Sea,ambiguity and vagueness often exist in the semantic expression of geographical features.The needs of spatial data or ganization andsharing are unable to be satisfied thereby.This paperintro duced the idea of geographical ontology to deeply analyze the domainknowledge of islands and related resource environmental features,and fully considered their concepts and relations.Then classes,attributes,relations and constra ints were well defined to achieve formal expressions of related concepts and relations of eachfeature.Therefore,an island ontology was established.Moreover,the spatial data were processed to be in a unified semantic expression based on the ontology.In order to support unified integration and manag ement of the spatial data,the mapping betweenisland and the spatial data were established by using quadtree coding algorithm.Finally,the application of island ontology wasshow n in the standardized ex pression of geo gr aphical o bjects and spatial data or ganization,and Yong xing Island and ocean wavedata were respect ively taken as case studies.Moreover,an island information retrieval was implemented to show the effect iveness of the pr oposed approach.The result showed that the ontology could effectively express the relevant knowledge of islandsand related resource environmental features,and had a certa in practical value.
