In the digital information era of rapid development of the Internet and increasing importance of cybersecurity,cyber-space geographic mapping is regarded as a new type of means of cognition and management of cyberspace.By synthesizing the in-formation of cyberspace and geospatial information,it is able to display the cyberspace situation more comprehensively from mul-tiple perspectives.However,the current research work on cyberspace geographic mapping lacks a fine-grained portrayal of cyber-space 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 conjunc-tion 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 im-prove the understanding of cyberspace,but also has practical application significance in cybersecurity,resource management,fault recovery,and decision making.
