摘　　要：利用计算机网络、数据库管理、地下空间三维可视化等技术,将地质勘探调查成果统一在三维可视化信息平台中集成,面向地质工作人员和管理人员提供综合数据服务,在一定程度上解决信息资源共享的问题。选择羌塘盆地和半岛湖重点区块,从已有地质认识成果出发,采用基于多源数据的交互建模方法,建立断层系统和沉积地层三维模型。基于Creatar三维基础平台研发了数据管理及三维可视化系统,实现了对羌塘盆地基础地质成果数据、基础地理数据、油气专业数据、盆地-区块三维模型数据、二维专题分布区图、DEM及遥感影像的集中管理,并可以分类、查询、检索和显示,为研究人员提供了一个直观的盆地勘探开发信息一体化查询、分析的可视化环境。By computer network,database management,and underground space 3D visualization technology,the geological exploration survey results are unified in the 3D visualization information platform,providing comprehensive data services for geological workers and managers,and useful for the information resource sharing to a certain extent.From the Qiangtang basin and the Bandaohu key blocks,based on the existing geological research,a 3D model of fault system and sedimentary stratum is established by using interactive modeling method based on multi-source data.Based on the Createar 3D basic platform,the data management and 3D visualization system were developed.The development helps the realization of the centralized management of the basic geological results data,basic geographic data,oil and gas professional data,basin-block 3D model data,2D thematic distribution area map,DEM and remote sensing image of the Qiangtang basin.It can be classified,queried,retrieved and displayed,providing an intuitive basin exploration and development integration of information query and visualization analysis environment for researchers.
