Geo-environmental information is an important basis for geohazard analysis and the integration of geo-environmental data is crucial in the construction of urban emergency management systems. In existing urban spatial information systems, the integration of geo-environmental data is neither intuitive nor efficient enough to support the analysis of geohazards well. On the basis of Web virtual globe, this paper proposes a comprehensive framework for the integration and analysis of geo-environmental data. This framework can effectively integrate geological data with a 3D geological model as a carrier, seamlessly connect geographic data, dynamically load real-time monitoring data, and build 3D visualisation and analysis scenes of urban full-space temporal information in the browser. The application example shows that the proposed framework can provide good geo-environmental data and practical data analysis functions for geohazard early warning and decision making, and improve the efficiency of government departments’ response to geohazards.

地缘环境信息是地质灾害分析的重要依据，地缘环境数据的整合对于城市应急管理体系建设至关重要。在现有的城市空间信息系统中，地质环境数据的整合既不够直观，也不够有效，无法很好地支持地质灾害分析。本文以Web虚拟地球为基础，提出了一个综合的地理环境数据集成与分析框架。该框架可以有效地将地质数据以3D地质模型为载体，无缝连接地理数据，动态加载实时监测数据，在浏览器中构建城市全时空信息的3D可视化和分析场景。
