摘　　要：城市作为地球上人口、经济、技术、基础设施最为发达,最为密集的区域,其信息体系结构复杂。随着"数字地球"概念在城市中的应用,"数字城市"应运而生。然而,有关城市的数字化信息存在尺度不一致、信息源分散、不同级别的数据杂乱等问题,为了解决上述问题,本研究提出了多尺度空间信息更新机制,通过不同制度、不同级别数据之间的实时交互,实现空间信息的更新,体现数字城市的服务职能。The city as the Earth＇s population, economy, technology, infrastructure is the most developed, most dense region, its complex information architecture, as the ＂Digital Earth＂ concept in the city, ＂digital city＂ came into being. However, the digital information exists about the city-scale inconsistencies, dispersion of information sources, the different levels of data clutter issues, in order to address the above issues, the study made a number of spatial information update mechanism, through real-time interaction between the different systems, different levels of data, implement spatial information update, reflecting the service functions of digital city.
