To solve current problems in the construction of urban geological information such as the lack of standards, the scattering of information,and the difficulty of data sharing,special attention is paid to geological features in the moun-tainous city of Chongqing. Key technologies are researched,such as the unified data standard,three-dimensional geological modeling framework,heterogeneous multi-source geological database,adaptive visualization of massive geological data,and plug-in application integration. The integrated management platform of geological information for mountainous city is devel-oped as well. Based on this platform,an integrated system of engineering geology information management for the Longzhou-wan public rental house is quickly built. It has been successfully applied to the display of geological information and three-dimensional visual analysis,which enhances the geological information services in mountainous city.%为解决当前城市地质信息化建设中存在的标准缺乏、信息分散、共享困难的难题,针对重庆山地城市地质特点,从统一数据标准、三维地质建模框架、多源异构地质数据库建设、海量三维地质数据自适应可视化、插件式行业集成应用等方面进行关键技术研究,研发了山地城市地质信息集成管理平台. 基于该平台快速搭建的龙洲湾公租房工程地质信息集成管理系统,成功应用到了场区地质信息展现及三维可视化分析决策中,提升了山地城市地质信息服务水平.
