基于知识图谱的公路工程领域GIS应用研究现状

为洞悉我国公路工程领域地理信息系统（Geographic Information System，GIS）应用研究的现状及热点，以2010—2020年中国知网（CNKI）数据库中的相关文献为数据源，综合运用COOC、GIGO、SPSS与UCINET等软件，通过聚类树状图分析、因子分析与多维尺度分析对公路工程领域GIS研究的高频关键词进行研究主题归类；采用社会网络分析法对公路工程领域GIS研究的关键词进行共现网络图谱绘制与中心性分析，以直观揭示其研究热点与结构. 研究结果表明:公路工程领域GIS研究的热点关键词为路线设计、边坡地质灾害易发性评价、滑坡监测和路面管理系统等；研究主题主要可分为GIS多样化研究及应用、公路交通网与地质灾害评价、公路管理信息化与可视化3大类.

Research status of GIS application in highway engineering field based on knowledge graph

In order to gain insight into current status and hotspots of geographic information system (GIS) application research in the field of highway engineering in our country, relevant documents in the CNKI database from 2010 to 2020 were used as data sources, and softwares such as COOC, GIGO, SPSS and UCINET were used comprehensively. The research topics of high-frequency keywords in the field were classified through clustering tree diagram analysis, factor analysis and multi-dimensional scale analysis; the social network analysis method was used to draw the co-occurrence network map and centrality analysis of the key words to reveal its research hotspots and structure intuitively. The results show that the hot keywords of GIS research are route design, slope geological hazard susceptibility evaluation, landslide monitoring, pavement management system and so on. Research topics can be divided into three main categories namely: GIS diversification research and application, road transportation network and geological disaster evaluation, road management information and visualization.
