摘　　要：在全球气候变暖的背景下,极端气候事件引起的生态效应研究受到广泛关注。基于2000—2020年中国知网和Web of Science核心合集数据库收录的913篇文献,利用计量工具CiteSpace对极端气候事件引起的生态效应研究现状进行可视化分析,并梳理其研究进展和趋势。结果表明:该领域的发文量经历了缓慢增长-平稳增长-迅猛增长三个阶段,同时期国内相较于国外发文数量严重不足,且相对分散;发文量最大的机构和作者分别为中国科学院与Beierkuhnlein Carl;出现频次较高的关键词有“气候变化”、“干旱”、“响应”、“温度”、“极端气候”等;当前关于极端气候事件的生态效应研究主要趋向于极端干旱、极端降水、极端温度对陆地生态系统的影响,极端气候下的生态系统碳循环、抵抗力稳定性、敏感性、动态演变等是近年来的研究热点。未来要规范极端气候事件相关术语,联合新技术手段开展离散型、复合型极端气候事件的长期生态效应研究。Under the global warming,the research on ecological effects caused by extreme climate events has received widespread attention.Based on a total of 913 literatures collected by the China National Knowledge Infrastructure(CNKI)and the Web of Science Core Collection database from 2000 to 2020,CiteSpace software was applied to visualize and analyze the current research status,progresses and trends of ecological effects caused by extreme climate events.The results showed that the number of publications in this field experienced three phases:slow growth,steady growth,and rapid growth.The number of publications in China was seriously insufficient and relatively scattered compared with that in foreign countries over the same period.The institutions and authors with the highest publications were the Chinese Academy of Sciences and Beierkuhnlein Carl,respectively.Keywords with high frequency of appearance included"climate change","drought","response","temperature",and"extreme climate".Current research on the ecological effects of extreme climate events mainly tends to focus on the impacts of extreme drought,extreme precipitation and extreme temperature on terrestrial ecosystems.The carbon cycle,resistance and stability,sensitivity and dynamic evolution of ecosystems under extreme climate have been research hotspots in recent years.In the future,it is necessary to standardize the terminology related to extreme climate events and to carry out long-term ecological effects research on discrete and compound extreme climate eventsusing new techniques methods.
