Abstract: The author, combining domestic and international research results of digital geological map, absorbing object-oriented thoughts and methods, utilizes unified modeling language (UML) to finish the building of an object-oriented digital geological map data model. From the view of cartography, the author, designs concept model and logical model of object-oriented digital geological map data model, defines logical relationships of interrelationship between the features of the model, and then briefly describes implement platform and process of physics model. Object-oriented data model for digital geological map, breaks normal forms of relational model, more reasonably and effectively integrate spatial data and attribute data, and provide a scientific, logical, reliable, operable machine-made and mode for efficient storage, management, analysis, application, visualization expression of digital geological map. This model only is an attempt and discuss, and particular design and implement is to be researched by further experiments.

摘要： 本文结合国内外的研究成果，吸收面向对象的思想和方法，利用统一建模语言UML，完成了面向对象数字地质图数据模型的建立。从制图学的角度出发，设计了数字地质图数据的概念模型、逻辑模型，定义了构成数字地质图各要素间的逻辑关系，并简要叙述了物理模型的实现平台和建立过程。面向对象的数字地质图数据模型打破了关系模型范式的限制，更加合理地将空间数据和属性数据有效地融合在一起，为数字地质图的高效存储、管理、分析、应用、可视化表达提供一种科学、合理、可靠、可操作性强的机制和模式，作为一种尝试和探索，具体的设计和实施还有待于进一步研究。
