摘　　要：草地生态系统作为全球陆地生态系统的主体类型之一,其固碳潜力较大,在全球碳循环和气候变化方面具有重要的调节作用。本文使用VOSviewer和CiteSpace两种可视化软件对Web of Science(WOS)核心合集和中国知网(CNKI)数据库中1999—2022年发表的4464篇论文进行计量学分析,以期揭示草地生态系统固碳功能领域的研究现状和发展态势。结果表明:草地生态系统固碳功能研究的发文数量总体呈现上升趋势。通过VOSviewer对WOS数据库中发文国家的分析显示,中国和美国是该研究领域的主要力量。利用CiteSpace对WOS和CNKI数据库中发文机构的分析显示,在WOS数据库中发文量位居前三的研究机构分别为中国科学院、美国农业部和中国科学院大学;在CNKI数据库中,西北农林科技大学、中国科学院大学和北京林业大学的研究最为活跃,但各研究团队的交流合作还需进一步加强。目前,该领域在两个数据库中的研究热点主要集中在气候变化、人类活动和土壤微生物群落对草地生态系统固碳功能变化的驱动作用,土壤碳储量的时空分异特征,以及草地生态系统固碳功能价值评估等方面。Grassland ecosystems,as one of the dominant types of terrestrial ecosystems worldwide,exhibit substantial carbon sequestration potential and play a vital regulatory role in the global carbon cycling and climate change mitigation.This article conducted a bibliometric and visualization analysis of 4,464 publications in the Web of Science Core Collection(WOS)and China National Knowledge Infrastructure(CNKI)database spanning from 1999 to 2022 by VOSviewer and CiteSpace.Current research status and development trends on carbon sequestration functions in grassland ecosystems were examined.The results revealed an increase trend in publication outputs on the carbon sequestration function of grassland ecosystems.Country distribution analysis of publications in WOS database by VOSviewer identified that China and the United States lead this research area.Institute analysis of publication by CiteSpace indicated that Chinese Academy of Sciences,the United States Department of Agriculture,and the University of the Chinese Academy of Sciences emerged as the top three in WOS database.Northwest A&F University,the University of the Chinese Academy of Sciences,and Beijing Forestry University were the most active institutes in the CNKI database.However,there is still potential for improving effective international communication and collaboration among nations and research teams.The bibliometric analysis identified three research hotspots in this field:the driving effects of climate change,human activities,and soil microbial communities on dynamics of carbon sequestration functions in grassland ecosystems;the spatiotemporal variation characteristics of soil carbon storage;and the evaluation of carbon sequestration functions in grassland ecosystems.
