摘　　要：数字地质调查系统是贯穿整个地质矿产资源调查全过程的软件,涵盖地质矿产调查、矿产资源勘查、矿体模拟、品位估计、资源量估算、矿山开采系统优化等内容。考虑数字地质调查系统的应用技术层面,从数据"层"模型、数据流"池"技术、不同阶段数据模型继承技术、数据互操作技术等几个方面讨论了核心技术及其实现,通过基于无缝一体化技术的数据采集、管理、综合处理与成果表达,在实体或矿块的矿床建模技术与品位估计、储量估算等方面展现了全地质调查过程的数字化,不但为地质人员应用高新技术降低了门坎,而且极大地提高了研究精度和效率,丰富了成果的表现形式和服务形式。随着数字地质调查系统的完善和应用水平的提高,数字地质调查系统将成为中国地质调查的主流软件体系。The digital geological survey system is software penetrating the whole process of geological and mineral resource survey. It covers digital mapping, geological and mineral resource survey, mineral resource exploration, orebody computer simulation, ore grade estimates, estimates of resources, optimization of the mine mining system etc. Proceeding from the applied technology, the key technology and its application in the digital geological survey system are discussed in aspects of the data ＂layer＂ model, data stream ＂pool＂ technology, inherited technology of data models of different stages and interoperable technology of data. Through data gathering, management and integrated processing and result expression based on the seamless integrative technology, the digitalization of the whole geological survey process is displayed with respect to the mineral deposit modeling technology of the entity or ore block, grade estimates and reserve estimates, which has not only lowered the threshold of the application of high-technology for geological work-rs, but also greatly Unproved the research precision and efficiency and enriched the expression and service forms of the outputs. The digital geological survey system will become the mainstream software system of China＇s geological survey with improvement of the system and upgrading of its application.
