摘　　要：数据组织是GIS系统建设的基础和前提,随着对地理世界认知的不断深入,逐渐形成了基于特征的空间数据模型。以基于特征的空间数据组织基本理论为基础,文章主要讨论基于GML3.2的空间数据组织与关系表达的关键问题。首先,简要介绍GML的基本概念,并详细阐述GML3.2的主要模式。在此基础上,讨论在GML应用模式设计中需要注意的相关原则。最后,总结探讨了实现基于GML3.2的对象化空间数据组织与关系表达的途径。The data organization is the foundation and premise of GIS system construction. With the development of cognition to the geography world, feature-based spatial data model has grown upgradually. Upon the principle theory of the feature-based spatial data organization, the article mainly discussed the related questions of the spatial data organization and its relation expression based on GML3.2. First, it briefly introduced the main concept of GML, and then it elaborated in details the main pattern of GML3.2. Second, it discussed the related principles that need to be noted in the design of the GML application schema. In the end, the paper summarized and discussed the realization path to the object oriented spatial data organization and relation expression based on GML3.2.
