摘　　要：基于面向对象技术和GIS空间数据模型理论建立地质剖面的概念模型和逻辑模型,并从计算生成地质剖面数据和地质剖面的可视化表达两个层面,分别建立了地质剖面的计算数据模型和表现数据模型.最后基于本文建立的地质剖面数据模型,实现了地质剖面的自动绘制、地质剖面图中断层和褶皱的可视化表达以及各对象拓扑关系的建立.On the basis of OO （object oriented） technology and spatial data model theory of GIS, the data models of automatic generating geologic section are built. Through the analysis of the relationship between bore and geologic section with geological structure, the concept model and the logic model of geologic section are built. The computing data model of geologic section is established from the perspective of working out the vector data of geologic section, and the expression data model of geologic section is proposed from the perspective of visualization of geologic section. Finally, based on all of the data models of automatic generating geologic section, the geologic section is atuomatically generated, the fault and fold in the geologic section are visualized, and the topological relationship of each object is built. 11figs., 10refs.
