近30年国外绿道理论研究进展与趋势——基于CiteSpace的图谱量化研究

以WOS(web of science)数据库中近30年主题词为“greenway”的367篇相关论文为研究数据,采用统计学方法和科学知识图谱软件(CiteSpace5),对国外1988-2018年绿道研究的文献发表情况和研究地区分布情况进行深入解析。通过关键词共词分析、聚类分析和时区分析等方式对研究热点进行总结归纳,并对其研究趋势做出展望。结果表明,国外的绿道研究在21世纪之前处于缓慢发展的状态,21世纪后开始受到众多研究者的关注。现阶段绿道的研究方向主要分为城市绿道的规划管理、生态网络及廊道建设和满足使用者需要三类,并向实现公平性、完善绿道评价体系、绿道功能扩展的方向发展。

Research Progress and Trend of Greenway Theory Abroad in Recent 30 Years:Quantification of Spectrum Based on CiteSpace

The research content of greenway theory is constantly developing and extending.In this paper,367 papers on“greenway”in WOS(web of science)database in the past 30 years are used as research data.Statistical methods and CiteSpace5 software are used to analyze the publication of Greenway research literature and the regional distribution of Greenway research in foreign countries from 1988 to 2018.Through keyword Co-word analysis,clustering analysis and time zone analysis,the research hotspots are summarized,and the research trends are prospected.The results show that greenway research in foreign countries is in a slow development state before the 21st century,and many researchers begin to pay attention to Greenway research after the 21st century.At present,the research direction of Greenway is mainly divided into three categories:planning and management of urban greenway,construction of ecological network and corridor and meeting user needs.The research of Greenway will develop towards achieving fairness,improving the evaluation system of Greenway and expanding the function of greenway.
