摘　　要：数字孪生是智慧城市建设的全新路径以及实践模式,数字底座是数字孪生城市建设的重要空间基底。通过数字孪生空间地理数字底座建设,最大限度采集生产数字孪生模式下的空间地理数据,可以为城市数字化转型提供有力支撑。本文根据上海智慧城市建设实践,从分析城市数字孪生以及空间地理数字底座的概念出发,提出了以数字孪生空间地理数据资源建设、数字孪生智能中枢构建以及时空数据服务体系建立为核心的城市数字孪生空间地理底座构建的技术架构和构建途径,并结合服务三维(3D)规划审批、土地利用全生命周期管理、智慧公安等具体应用场景,为城市空间地理数字底座在城市治理中的进一步应用提供参考。Digital twin is a new path and practice mode for smart city construction,and the digital base is an important spatial foundation for the construction of digital twin city.By constructing the digital twin spatial geographic digital base,the collection and production of spatial geographic data in digital twin mode is maximized,which provides strong support for the digital transformation of cities.Based on the practice of smart city construction in Shanghai,this paper analyzed the concept of digital twin cities and spatial geographic digital base.The technical architecture and construction approach of the spatial geographic base of digital twin cities was proposed,which was centered on the construction of digital twin space geographical data resources,the construction of digital twin intelligent hub and the establishment of spatio-temporal data service system.Combined with specific application scenarios such as three-dimensional(3D)planning approval,land use life cycle management,and smart police,this paper can provide references for the further application of city spatial geographic digital base in urban governance.
