基于CiteSpace的国内外城市植物多样性研究对比分析

Comparison of Research Progress on Urban Plant Diversity between Domestic and Foreign Based on Citespace

为了综合比较国内外城市植物多样性的研究进展,采用CiteSpace可视化软件分别对中国知网(CNKI)数据库和“WOS核心合集”数据库进行检索。从年发文量趋势、主要研究作者、机构、热点及趋势四个方面进行对比分析,得出以下结论:①国内研究经历了3个阶段:1998-2002的起步阶段、2003-2010年的探索阶段、2011-2020的稳定阶段;国外研究经历了两个阶段:2002-2008年的起步阶段和2009-2020年的快速发展阶段。②国内发文量较高的研究团队相对集中,且数量较少,合作关系相对不紧密;国外的研究者们则形成了相对稳定且数量较多的合作关系。③国内的研究机构主要集中在各大高校,且彼此间的合作较少,至多以3个机构之间形成合作关系;国外的研究机构则彼此间合作紧密。④国内的研究需丰富研究内容,扩大研究尺度,加强作者和机构之间的合作,逐步推进城市植物多样性的保护研究。生态系统服务和功能多样性将会是国内外今后的研究热点。

In order to comprehensively compare the research progress of urban plant diversity between domestic and foreign,CiteSpace software was used to retrieve CNKI database and“WOS core collection”database,respectively.From the trend of annual publication,the main research authors,institutions,hotspots and trends to compare and analysis,The conclusions are as follows:①Domestic research has experienced three stages:the initial stage from 1998 to 2002,the exploratory stage from 2003 to 2010,and the stable stage from 2011 to 2020;Foreign research has gone through two stages:the initial stage in 2002-2008 and the rapid development stage in 2009-2020.②Domestic research teams with large number of papers are relatively concentrated,and the cooperation relationship is weak;Foreign researchers have formed a relatively stable and cooperative relations,and the links between scholars are very close.③The domestic research institutions are mainly concentrated in major universities,and there is little cooperation between them,and at most three institutions form cooperative relations;Foreign research institutions cooperate closely with each other,and most of them have lots of partners.④The domestic research needs to enrich the research content,expand the research scale,strengthen the cooperation between authors and institutions,and gradually promote the conservation of urban plant diversity.Ecosystem service and functional diversity will be the research focus at home and abroad in the future.
