基于文献计量的生态修复成效评估研究进展与展望

Effectiveness evaluation by bibliometrics of ecological restoration

气候变化和人类活动导致的生态系统退化和脆弱加剧等问题备受世界关注,生态修复成为恢复受损生态系统的主要途径.生态修复的成效评估是确保生态修复质量和效果的关键环节,并为改进和完善生态修复工作提供科学指导.国内外关于生态修复成效评估的相关研究数量日益剧增,但缺乏系统的文献梳理,对研究领域发展历程和研究热点演变的认识不足.本文基于Web of Science和中国知网数据库,运用文献计量学软件CiteSpace知识图谱可视化方法,对国内外生态修复成效评估研究文献进行发文作者、发文机构、文献共被引和关键词共现分析,并在此基础上进行了展望.结果表明:1)1996-2023年,国内外生态修复成效评估研究发文量呈增长趋势,其中国际文献数量增长更快;2)中国科学院和中国科学院大学的发文量在国内外均处于领先地位,北京师范大学和西北农林科技大学在国际上发文量较多,北京林业大学在国内发文量较多;3)生态修复成效评估研究可以分为3个阶段,即1996-2005、2006-2015和2016年及以后,它们分别对应生态修复成效评估的早期探索阶段、体系完善阶段和快速发展阶段;4)国内外文献的关键词重合度和同步性均不高,相较之下,国际研究更加多元化,但国内近2年研究主题有所拓展,更加关注生态系统整体性保护和多尺度综合评价.

Ecosystem degradation and increased fragility due to climate change and human activities have attracted worldwide attention,ecological restoration is the main way to restore damaged ecosystems.Effectiveness evaluation of ecological restoration is key to ensure quality and effect of ecological restoration,to provide scientific guidance for improving and perfecting ecological restorations.Such studies at home and abroad are increasing rapidly,but are not systematically reviewed.Web of Science and CNKI databases are analyzed with CiteSpace visual knowledge graph analysis tool with regards to authors,institutions,co-citations and keywords.1)From 1996 to 2023,the total number of papers in the field showed an overall upward trend,with international papers growing faster.2)Chinese Academy of Sciences and University of the Chinese Academy of Sciences were the top institutions that published a large number of papers.Beijing Normal University and Northwest A&F University published a large number of papers abroad,while Beijing Forestry University had published many papers domestically.3)Such researches were divided into three stages:1996-2005,2006-2015,and 2016 and beyond,corresponding to early exploration,system improvement and rapid development stages respectively.4)The coincidence degree and synchrony of keywords of domestic and international papers were not high.In comparison,international research was more diversified,while domestic research topics had expanded in the past two years,especially in the area of overall protection of ecosystems and multi-scale comprehensive evaluation.
