CiteSpace bibliometric analysis of research progress and hotspots on the drought-induced tree mortality
摘要
Abstract
[Objective]This study aimed to comprehensively sort out the research process and hotspots of drought-induced tree mortality.[Method]By using CiteSpace software,this paper analyzed the authors,institutions,countries(regions),keywords and other relevant information of literatures on this topic based on two databases:China national knowledge infrastructure(CNKI)and Web of Science(WOS).The analyzed data in this paper are composed of 153 Chinese and 1 757 English literatures published from 2000 to 2023.[Result]The results revealed that the field of drought-induced tree mortality had made significant progress and exhibited steady growth throughout the research period.Authors from the United States,Spain,and China contributed to over 50%of the international publications.Domestic and international studies had focused on research hotspots such as carbon starvation,hydraulic failure and water stress,and a large number of studies had also been carried out on drought,tree death,climate changes and extreme climate in combination with native tree species.From the perspective of mechanisms,there were two main directions:hydraulic failure and carbon starvation;and in terms of research objects,the main focus is on European beech and giant sequoia.[Conclusion]Through the analysis of the literatures on drought-induced tree mortality,this article aims to display the current research status and hot spots of drought-induced tree mortality at home and abroad,and to provide a reference for further domestic research.关键词
