摘要(Abstract)：

随着城市三维地质信息系统及其应用的快速发展，对地学数据的可视化表达精度的需求变得越来越高，但地质调查数据常具有多源、多维、海量、多专题、多尺度和多时态等特征，而三维数据存储、组织与管理己成为制约其发展的重要因素。因此如何高效管理并有效利用这些复杂且海量的地质数据去解决各种复杂的地质问题服务社会，成为了城市地质信息科学领域研究的热门方向。基于武汉市多要素城市地质调查全空间一张图的构建过程，从多源三维模型一体化融合管理与分布式存储、轻量级全空间三维模型构建、多源异构海量三维数据快速渲染和浏览器端三维模型分析及专业应用4个方面系统地探索了城市地质调查全空间一张图系统建设过程中的关键技术，并进行了应用实践。研究结果实现了城市级大规模高精度三维地质模型的高效集成，提高了多要素城市地质调查成果可视化的表达效果，为三维地质模型的应用奠定了坚实的基础。
