摘要
网络实体资源测量结果多以文本和表格形式展现，难以直观感知其在空间上的分布。针对该问题，本文采用分层分级和聚合解聚思想，用定性和定量两种表现方式，设计并实现了基于Web端的网络空间实体资源可视化系统，取得了较好的表达效果。针对系统实现过程中出现节点分布不可信的问题，进行了网络空间测绘成果可靠性分析；开展了地理空间辅助下的网络实体资源缓冲区分析等应用初探，可为后续网络空间测绘可视化表达和应用提供参考。
Since the results of eyberspace entity resource measurement are mostly displayed in the form of text and table, it is difficult to intuitively perceive the spatial distribution of cyberspace resources. In order to solve the problem, the layering, hierarchy, polymerization and depolymerization concepts are adopted to design and implement a Web-based visualization system of cyberspace entity resources in qualitative and quantitative ways respectively to acquire better visual performance. The reliability of surveying and mapping results in network space is analyzed to deal with the unreliable distribution of nodes in system implementation, and a preliminary study on the application of geospatial-assisted cyberspace resources buffer analysis is carried out, which will provide reference for the development of the follow-up visual expression and application of cyberspace mapping.
