摘　　要：随着社会经济建设的不断发展,城市精细化管理不断深化,如何建立多渠道、多路径的更新机制,将变化的基础地理信息数据及时更新到城市空间数据库中,决定了空间地理信息应用的生命力。首先概述了上海城市精细化管理对空间地理信息的现势性需求,并分析了传统更新模式的不足,研究以管理驱动、遥感监测、现状调查3种模式与基础地理信息迭代更新的内在联系及实现机制,并结合具体实施情况验证了更新机制的可行性,为完善空间地理数据应用共享提供借鉴。The vitality of the application of spatial geographic information is determined by establishing a multi-channel and multi-path updating mechanism which updates the changed basic geographic information data to the urban spatial database with the deepening of urban delicacy management.The paper describes current demands of spatial geographic information for the support of urban governance in Shanghai,and studies the internal connection and iteratively updating mechanism of basic geographic information with three modes of project driven,grid inspection,and remote sensing monitoring.The feasibility of the updating mechanism is verified by analyzing the specific implementation.The study could serve as reference for improvement of the data application and sharing.
