摘　　要：由于地质数据及其应用本身所具有的复杂性、不确定性、信息不完备等特点,使得三维地质建模成为制约三维GIS研究及其应用的主要瓶颈之一。讨论三维空间数据模型的设计,提出“多元数据—多方法集成—多层次干预”的“三多”建模思路;从建模尺度、数据源、建模工具等方面对建模方法进行分类;分析三维地质建模的关键技术,包括三维地质模型构建、海量模型数据操作和多元数据一体化耦合显示;针对三维地质建模系统的开发提出6项建议,分析近期三维地质建模的研究热点。Geological complexity, uncertainty, limited sample data, etc., make Three - Dimensional Geological Modeling（3DGM） a bottleneck for the development and applications of 3D GIS. This paper firstly proposes three key points in designing 3D spatial data models for 3DGM： different models for different applications, rules for model design, integration of vector and raster models. Secondly, the modeling ideas of multi - source data, multi- method integration and multi- level interactions are presented. Thirdly, current methods for 3EGM are classed from several views of scales,source data,modeling tools,etc. And then three key technologies in 3DGM of complex geological model building, massive model data processing and integrative visualization of multi - data are analyzed. At last, comments on 3DGM software development and the latest research hot points are discussed.
