中文摘要：

以田野考古发掘中的空间地层为研究对象,从田野考古地层的特性描述分析入手,分析其模型构建的需求.在对多层DEM和似三棱柱体进行阐述分析的基础上,基于面向对象的思想,提出基于多层DEM与QTPV的地层建模方法,并结合考古地层数据源类型,阐述了具体的地层建模过程.在此基础上设计了地层逻辑模型和数据结构,并以具体的钻孔数据进行了地层三维可视化验证.设计的模型顾及了空间对象之间的拓扑关系,方便空间对象的可视化与空间分析,为田野考古GIS的开发提供了模型支持和基础.

英文摘要：

Based on the object-oriented approach author took the 3D（three-dimensional）spatial stratum in field archaeology as the research objects and analyzed the spatial stratum and the demand of data model.By the analysis and comparison of DEMs（Digital Elevation Models） and QTPV（Quasi Tri-Prism Volume）,the author put forward the stratum 3D spatial data model based on DEMs and QTPV.Besides,the detailed methods and steps of modeling for kinds of stratum data resource were presented.And then the relative logic model and data structure were designed,finally the data model was realized and completed by 3D visualization with some drilling data.All of the above research implements the unification of stratum data model of FAGIS（Field Archaeology Geographical Information System）,considering the topological relations between the spatial objects and is convenient for 3D visualization and spatial analysis,and which becomes the basis of FAGIS.
