摘　　要：在互联网快速发展且网络安全愈发重要的数字信息时代,网络空间地理图谱被认为是认知和管理网络空间的新型手段,其通过综合网络空间和地理空间的信息,能够从多个角度更加全面地展示网络空间态势。但目前对于网络空间地理图谱的研究工作缺乏对网络空间模型细粒度的刻画,也缺乏网络空间地理图谱的具体构建方法和应用方式。针对上述问题,以网络空间认知为目标,文中扩展提出了一个带有时间参考轴的四层四级的网络空间分层模型。此外,为了更好地理解复杂的网络空间环境,还结合知识图谱技术,提出了一个构建网络空间地理图谱的具体框架以及构建网络空间本体的方法。基于Censys的真实测绘数据,成功构建了一个模拟园区网络的网络空间地理图谱原型。本研究提出了对网络空间分层结构的改进方法,同时也将知识图谱引入网络空间地理学的研究领域。这不仅有助于提高对网络空间的理解,而且在网络安全、资源管理、故障恢复、决策制定等方面具有实际的应用意义。In the digital information era of rapid development of the Internet and increasing importance of cybersecurity,cyberspace geographic mapping is regarded as a new type of means of cognition and management of cyberspace.By synthesizing the information of cyberspace and geospatial information,it is able to display the cyberspace situation more comprehensively from multiple perspectives.However,the current research work on cyberspace geographic mapping lacks a fine-grained portrayal of cyberspace model,as well as specific construction methods and application methods of cyberspace geographic mapping.To address the above problems,with the goal of cyberspace cognition,this paper proposes a four-layer,four-level cyberspace hierarchical model with a time reference axis.In addition,in order to better understand the complex cyberspace environment,a specific framework for constructing a cyberspace geographic mapping,as well as a method for constructing a cyberspace ontology,is proposed in conjunction with the knowledge graph technology.Based on real mapping data from Censys,a prototype cyberspace geographic mapping of a simulated park network is successfully constructed.This study proposes an improved approach to the hierarchical structure of cyberspace,and also introduces knowledge mapping into the research field of cyberspace geography,which not only helps to improve the understanding of cyberspace,but also has practical application significance in cybersecurity,resource management,fault recovery,and decision making.
