摘要： 研究了地上三维场景模型与地下三维矿体模型的构建方法，提出了基于散点构网的地质实体充填算法模型.结合地理信息系统的建设方法，以辽宁某铁矿为原型，开发了其地上下三维可视化信息系统，实现了各类三维模型的创建、三维显示与浏览、空间属性查询、交互操作、测量与空间分析等功能.系统既实现了地上下三维模型的快速建立，又解决了以往三维模型中只能显示，不能查询、量测、编辑等问题，可以宏观地把握、微观地洞察矿区地上下整体地形地质特征和地理信息空间分布，更客观全面地表达矿山三维地理信息实体，可作为数字矿山、智能采矿的基础.

关键词: 地上下三维GIS, 算法融合, 三维模型构建, 模型更新, 系统开发

Abstract: Filling algorithms based on unorganized discrete points were proposed to build geological entities by analyzing the 3D scene models on the ground and 3D orebody models underground. Combined with the methods of developing geographic information system(GIS)， a ground and underground 3D visualization information system was constructed according to an iron mine in Liaoning， which includes the functions of fast modeling， 3D browser and display， spatial attribute query， interoperate measurement and spatial analysis and so on. With the system， 3D models of ground and underground entities enable to be built， queried， measured and edited， and the problems that can be only displayed were solved. Besides， the terrain characteristics and the spatial distribution of mine geographic information were observed at both macro and microlevel， and then the 3D geographic information entities in the mine were expressed more intuitively and comprehensively， which could be the foundation of digital mine and intelligent mining.

Key words: ground and underground 3D GIS, algorithm fusion, 3D model construction, model upgrade, system development
