【摘要】 地理系统研究对象的复杂性决定了地理信息的多语义性，地理信息分类编码是地理信息数据组织的重要方式。如何对地理对象进行准确地界定和分类表达，如何快速地获取和准确地表达用户需求，是困扰信息系统开发的难题。本体论及相关技术的引入为解决上述难题提供了全新的视角，并提供了强有力的理论和方法支撑。 在基于本体的地质环境管理信息系统设计开发过程中，地质环境领域本体构建、基于本体的需求分析和基于本体的分类编码是其中重要的三个环节。论文从本体的相关理论研究入手，总结了本体概念的实质和内涵，探讨了本体的类型、作用、构建方法、形式化表达以及本体的构建工具。在综合前人研究基础上，总结提出了本体构建的五步方法，并将其应用于地质环境管理信息系统的本体构建中。通过概括地质环境的领域和范畴，获得地质环境中涉及的本体术语和概念；从而提出了地质环境本体的体系框架，并逐层抽象建立地质环境的元本体，分别进行了属性、关系描述和实例化分析；探讨了如何利用地理本体的知识和组织表达，帮助用户描述系统的需求，规范需求获取的过程；针对传统分类编码方法的不足，提出了柔性分类动态编码方法，从而构建了本体与传统分层数据表示方式的映射关系。更多还原

【Abstract】 The complexity of Geographic system determines the multi-semantic of geographic information and geographic information classification and coding is important GIS data organizations. How to accurately define and target geographic classification expression and how quickly and accurately express the user demand is plaguing problems of information system developer. The introduction of ontology and relevant technologies address the problem with a brand new perspective and provide a strong theoretical and methodological support.For identity in the geological environment management information systems design and development process, the identity of geology environment field ontology, ontology-oriented field requirements analysis and ontology-oriented field classification and coding are three important aspects. From the relevant ontology theoretical study, papers summarize the essence and connotation of the concept of ontology, explore the type, role, a method, formalized expression and tool of ontology. On the basis of existing research, papers bring forward 5-step method of ontology building and use this method to build ontology in geological environment management information systems. Through generalizing field and category of geological environment, obtain the terminology and concepts of ontology involved in geological environment field. On this basis papers propose the framework of geological environment ontology .establish the meta-ontology of geological environment using embedded abstract method and analyze attributes, relationships description and instantiation separately .Papers explore how the use of the knowledge and organizational expression of geo-ontology to help users to describe system requirements, standardize the process of obtaining requirements. Against the inadequateness of the traditional classification and coding methods, Papers establish a flexible classification and coding methods thus build the mapping between ontology and traditional Tiered data Expression.更多还原
