基于文献的城市关联基础设施研究知识图谱与关联性分析

Research on Mapping Knowledge Domains and Correlation Analysis of Urban Interdependent Infrastructures Based on Literature

城市基础设施是城市维持正常社会经济活动的基础。近年来,我国城市基础设施建设规模持续攀升,各基础设施系统间的关联关系日益紧密,形成了具有相互影响和作用关系的关联系统。该文采用citespace软件分析关联基础设施相关文献的时间和空间分布特征,构建关联基础设施相关研究知识图谱以及关键词时间线图,识别研究热点领域,并选取7类传统基础设施和7类新型基础设施,以Jaccard指数和Salton指数作为定量指标衡量各基础设施之间的关联性。结果表明,“级联失效”“关联网络”“复杂系统”等关键词是关联基础设施领域重点关注的方向,物联网-云计算、电力-燃气/天然气、电力-电信/通信等基础设施系统之间的关联强度较高。

Urban infrastructure is the basis for maintaining normal social and economic activities in a city.In recent years,infrastructure systems are increasingly interconnected in China,subsequently an interacted system in which infrastructures are closely related and interdependent is formed.In this paper,citespace is used to analyze the temporal and spatial distribution characteristics of relevant literatures,meanwhile,the knowledge map and the timeline map of keywords are constructed to identify research hotspots.Jaccard index and Salton index are adopted to measure the interdependencies between infrastructures composed by 7 traditional infrastructures together with 7 new infrastructures.The results show that cascading effect,interdependent network and complex system are the key areas of related research field,and Internet of Things/IoT-cloud computing,electricity/electric power-natural gas/fuel gas,electricity/electric power-communication/telecommunication are highly interdependent.
