Research Status and Hot-spot Analysis of Natural Regeneration of Forest Ecosystem Vegetation
摘要
Abstract
[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.关键词
