[目的]为未来开展森林生态系统恢复和经营管理提供参考依据.[方法]基于Web of Science和中国知网数据库,通过可视化文献分析工具CiteSpace,对2000至2021年全球已发表的有关森林生态系统植被自然更新研究的相关文献进行分析.[结果]该领域的历年发文量呈波动上升趋势,美国、巴西、加拿大的发文量排在全球前列,在国际间保持着紧密的合作关系.国内发文量远低于国外,增长趋势缓慢且相关研究起步较晚,国际影响力较弱,与森林资源丰富的国家相比具有明显差距.国外以ZHU J J、KAREN D H、DANIEL C D等为核心作者形成的研究团队引领着该领域的发展.国内多以科研院所形成的团队内部合作为主.生态类期刊是该研究领域学术成果展示的重要平台,《Forest Ecology and Management》期刊收录的相关文献最多,国内核心期刊发文量处在第一位的是《生态学杂志》.目前国内外对森林植被自然更新影响因素的研究多分布在光照或林窗动态、种子库或种子雨、火烧、水分、人为干扰等方面.探究林隙/林窗、土壤、火、种子特性的影响机制是该领域近几十年的研究热点.[结论]气候变暖引起的夏季极端干旱以及人类对土地的不合理利用造成的植被更新障碍问题成为全球在该领域的新兴研究前沿.
[Objective]To provide a reference basis for future forest ecosystem restoration and management.[Method]A visual literature anal-ysis tool CiteSpace was used to analyzed the liferatures on natural regeneration of forest ecosystem vegetation from 2000 to 2021 based on the two databases of Web of Science and CNKI.[Result]The number of publications in this field fluctuated upward over the years,with the United States,Brazil and Canada ranking among the top in the world and maintaining close cooperation with the international community.The number of domestic publications was much lower than those of foreign countries,with a slow growth trend,a late start of related research and a weak international influence,thus there was an obvious gap compared with countries rich in forest resources.Foreign research teams were leading the development of the field formed by core authors,such as ZHU J J,KAREN D H,DANIEL C D and so on.Domestic research institutes were mainly engaged in internal team cooperation.Ecological journals were an important platform for displaying academic achievements in this re-search field.The journal of Forest Ecology and Management contained the most relevant literature,and the domestic core journal Chinese Jour-nal of Ecology had the largest number of articles.At present,global researches on the influencing factors of natural regeneration of forest vegeta-tion were mostly distributed in light or gap dynamics,seed bank or seed rain,fire,water,human disturbance and so on.Exploring the influen-cing mechanisms of forest gaps,soils,fire and seed germination had been a hot research topic in recent decades.[Conclusion]The problems of extreme summer droughts caused by climate warming and barriers to vegetation regeneration caused by unreasonable land use were emerging research frontiers worldwide in this field.
