摘要
为了把握土壤种子库在国内外的研究现状及研究前沿动态,客观反映各个国家、机构及研究者在该领域的影响力,本文基于文献计量学分析方法,对Web of Science数据库1999—2020年和中国知网数据库1983—2020年的研究成果进行了分析。结果表明:该领域的科研成果在国内外的发文趋势不同,国外期刊论文逐年上升,但国内论文自2009年以后开始下降。在发文量的国家排序中,美国排名第1,澳大利亚和中国分别位列第2和第3。国家间合作关系密切程度不大,相比较而言,美国的合作贡献量最大。中国科学院在该领域的发文量最多,总被引次数也最大,刊载该领域论文的外文期刊主要为《Plant Ecology》《Journal of Vegetation Science》和《Applied Vegetation Science》,中文期刊主要为《生态学报》《生态学杂志》和《植物生态学报》,该领域的文章在外文论文中主要集中在环境科学与生态学、生态学和植物科学3个学科,而国内主要集中在农业资源与环境、林学、生物学3个学科。目前,有关土壤种子库的研究主要集中在对种子库中种子本身特征、与地上植被的关系、土壤中种子持久性和在生态重建中的应用等研究上。有关土壤种子库的研究应积极探索新的科学问题,顾及更多研究领域,加强在解决实际问题中的作用,提高我国在该领域的科研水平和影响力;结合全球气候变化所带来的生态问题,加强国际间的研究合作关系,在全球尺度上利用土壤种子库反映生态变化,为解决生态问题提供决策参考。
In order to grasp the research status and frontier trends of the soil seed bank at home and abroad,and objectively reflect the influences of various countries,institutions and researchers in this field,this article,based on bibliometric analysis,analyzed the related research results of Web of Science database from 1999 to 2020 and CNKI database from 1983 to 2020.The results showed that the trends of scientific research are different at home and abroad.Papers have increased year by year in foreign journals but have declined since 2009 at home.In the rankings of published documents countries,the United States ranks first while China ranks third.The degree of close cooperation between countries is relatively small.In comparison,the United States has the largest contribution to cooperation.The Chinese Academy of Sciences publishes the most articles and has the largest total citations.The main foreign journals that publish related papers are Plant Ecology,Journal of Vegetation Science and Applied Vegetation Science,and the main Chinese journals are Journal of Ecology,Journal of Ecology and Plant Ecology Journals.Papers in this field are mainly concentrated in the three disciplines of Environmental Science&Ecology,Ecology and Plant Science in foreign papers,while mainly concentrated in the three disciplines of Agricultural Resources&Environment,Forestry and Biology at home.At present,the research on soil seed banks mainly focuses on the characteristics of the seeds in the seed bank and their relationship with the aboveground vegetation,the seed persistence in soil and the application of ecological reconstruction.In the future,research on soil seed banks should actively explore new scientific issues, take into account more research fields, strengthen the role in solving practical problems, and improve China's scientific research level and influence. Combining with the ecological problems brought about by global climate change, strengthen international research cooperation, use soil seed banks to reflect ecological changes on a global scale, and provide decision-making reference for ecological problems.
