城市信息空间是以城市地域空间为基础,以城市信息要素为载体,借由信息流实现城市信息纵向贯通、横向互联的虚拟空间。新一代信息技术正推动着信息空间结构和层次的提升,智慧城市代表了高级阶段的城市信息空间,其数据采集、信息交互、系统应用表现为透彻感知、深度互联、智能应用的特点。基于信息空间理论,本文提出了智慧城市的“3I”信息空间,即感知空间、互联空间和智能空间,并构建了智慧城市的三维模型,旨在丰富智慧城市相关的理论体系,为中国智慧城市实践提供指导。

Information space of an urban system is a virtual space based on urban geographical space, which is filled with information elements, and interconnected by information flows both longitudinally and laterally. The development of new generation information technology is upgrading both structure and level of information space. Smart city which represents the advanced stage of urban information space has characteristics of thorough perception, interconnection, intelligent application in the process of data collection, information exchange and system application performance. Based on the information space theory, "3I" information space including instrumented, interconnected and intelligent space is proposed, and a three-dimensional model of smart city is constructed to enrich the theoretical system, so it can provide the guidance for China's smart city practice.
