基于CiteSpace的国内外生态足迹研究知识图谱比较

Comparison of Mapping Knowledge Domain of Ecological Footprint Researches Between Chinese and Foreign Literatures Based on CiteSpace

为了综合比较国内外生态足迹领域的研究现状与热点演进,采用文献计量方法,以X指数为主要评价依据,通过对2000—2016年CNKI核心数据库1278篇、WOS核心合集1978篇生态足迹主题文献进行分类统计,从刊文量、X指数、h指数、篇均被引数、共现关键词和共引文献6个方面对国内外文献进行了评价和比较分析。结果表明:(1)发文量年际变化轨迹,CNKI呈下开口抛物线,WOS呈直线上升。(2)WOS文献影响力前三位的国家和地区依次为美国、英格兰和澳大利亚。(3)WOS影响力前三位的科研机构依次为中国科学院、加州大学系统、全球足迹网络;CNKI影响力前三位的科研机构依次为中科院地理科学与资源研究所、北京大学、南京大学。(4)WOS X指数前三位分别为:Ecological Economics,Ecological Indicators,Journal of Cleaner Production;CNKI期刊X指数前三位分别为《生态学报》、《安徽农业科学》和《资源科学》。(5)关键词共现分析表明,国内生态足迹的研究比国外活跃。综述了生态足迹研究的主要方向,为国内未来研究提出了启示。

The status quo of ecological footprint was assessed by critically reviewing current publication, which was collected from both core col- lection of China Academic Journals Full - text Database（CNKI） and Web of ScienceTM Core Collection of Science Citation Index Expanded Database （WOS）. The search topic in the article used was ecological footprint, and literature both in Chinese and English during the period of 2000 - 2016 were included in the analyses.The bibliometrics method based on the literatures data of 1278 and 1978 core papers from CNKI and WOS core collection, respectively. The number of published papers, X index （main evaluation indicator）, h index, average citations per ihem, co - occurrence keywords and co - citation literatures on ecological footprint were evaluated and compared between China and foreign nations. The results showed that：①The interannual change trajectories of total publications of CNKI and WOS exhibited downwards parabola and increasing linear model, respectively. ②The top 3 influential countries and territorirs from WOS literatures were the USA, England and Australia. ③The top 3 influential institutions from WOS literatures were Chinese Academy of Sciences（CAS）, University of California System and Global Footprint Network（GFN）. The top 3 influential institutions in CNKI literatures were Institute of Geographical Science and Resources in CAS, Peking University and Nanjing University. ④The top 3 influential journals of WOS and CNKI literatures were Ecological Economics, Ecological Indicators, Journal of Cleaner Production and Acta Ecologica Sinica, Journal of Anhui Agricultural Sciences, Resources Science, respectively. ⑤The keywords co - occurrence analysis showed that the research spots of China were more plentiful than that of foreign nations. The main research subfields were summarized and some implications were provided for the Chinese research on ecological footprint in the future.
