摘　　要：在地质研究不断深入和地理空间信息科学蓬勃发展的背景下,三维可视化地质建模技术已成为信息科学与地球科学交叉领域的研究热点。笔者对传统的三维地质建模方法进行研究、改进,形成一种新型的三维地质建模新方法。新型三维地质建模方法主要应用于地质领域,在多源异构地质数据融合、大规模高精度建模、地质网格细分、属性建模技术和遥感图像融合等方面取得了新的进展。笔者以成都—昌都区域为例,以地质钻孔数据、成都图幅、昌都图幅、遥感数据为数据源,利用新一代三维地质建模技术,进行了三维地质建模和可视化显示。成都—昌都区域的三维可视化验证了新型三维地质建模方法的可行性和有效性。同时也为全国重要地质钻孔数据服务平台对社会公开发布覆盖全国31个省(区、市),累计进尺达2.75亿m的110万个重要钻孔数据三维地质建模提供了重要方法。Under the background of the deepening of geological research and the vigorous development of geospatial information science 3 D visualization geological modeling technology has become a research hotspot in the interdisciplinary fields of information science and earth science. In this study, the traditional 3 D geological modeling method is studied and improved to form a new 3 D geological modeling method. The new 3 D geological modeling method is mainly applied in the geological field, and new progress has been made in multi-source heterogeneous geological data fusion, large-scale high-precision modeling, geological grid subdivision, attribute modeling technology, remote sensing image fusion and other aspects. Taking the Chengdu-Changdu region as an example, this paper uses the new generation of 3 D geological modeling technology to carry out 3 D geological modeling and visualization with geological borehole data, Chengdu map, Changdu map and remote sensing data as data sources. The 3 D visualization of Chengdu-Changdu region verifies the feasibility and effectiveness of the new 3 D geological modeling method. At the same time, it also provides an important method for the national important geological borehole data service platform to publicly release 1.1 million important borehole data 3 D geological modeling covering 31 provinces(autonomous regions and municipalities) in China with a cumulative depth of 275 million meters.
