摘　　要：目前,数字城市建设面临着新的技术、理论、数据、社会与应用背景,上升为数字工程新阶段。基于对上述背景及数字工程理念的分析,提出了建设当代数字城市的技术思路。在对数据、网络和标准整合的基础上,建立数据平台和网络平台;然后,在对各种应用系统整合的基础上,采用先进的分布式计算和GIS等技术,构建数字城市基础信息共享平台;在以上基础上,结合专业模型应用技术与专题数据库,实现数字城市的各种应用,最终建立统一、集成、完备和智能化的数字城市基础设施。并以"数字常平"为例进行了分析论证。Modern digital city building is facing the new background of science and technology, and now it has already entered a new stage of digital engineering. According to the analyses of the background,this paper puts forward to a technical line of digital city building：Based on the integration of data, network and standards, the data platform and network platform should be built ; Then, basis inthe integration of exiting systems, the share and operation platform of foundational spatial information should be built by using the technologies of GIS, distributed computing and so on;Finally, at all bases above and the professional technologies and data, various industry application systems should be built, and then a unified, integrated, comprehensive and intelligent digital city infrastructure has been set up. A engineering example is given at the end of this paper.
