    摘要:

    为了深入了解青藏高原土壤呼吸的研究现状与研究前沿,以中国知网数据库(CNKI)和Web of Science核心合集数据库中的相关文献为数据源,基于文献计量的分析方法,运用Citespace和VOSviewer等软件,通过对国内外发文趋势分析、高频关键词共现分析及国家、机构、作者合作网络分析等,总结了青藏高原土壤呼吸的研究热点与研究趋势。结果表明:(1)国内外青藏高原土壤呼吸的研究在逐年上升,外文研究的增长速率大于中文研究。(2)国内外关于青藏高原土壤呼吸的合作网络较为松散。(3)青藏高原土壤呼吸的研究大体划分为三个阶段:起步阶段(1978-2005年)、增长阶段(2006-2013年)、快速发展阶段(2014年-至今),研究方法、研究尺度都在不断发展。(4)目前土壤呼吸领域研究内容以青藏高原土壤呼吸与全球气候变化、氮添加与土壤呼吸、土壤呼吸与土壤温度、土壤呼吸与过度放牧为主。研究指出:在未来,应该加强对于青藏高原碳动态的连续观测,完善不同类型生态系统土壤呼吸研究。同时,探索放牧等生态系统管理措施对青藏高原土壤呼吸的影响机制。这些结果为国内外青藏高原土壤呼吸研究方向提供了可靠情报支持。

    Abstract:

    In order to gain an in-depth understanding of the research status and research frontiers of soil respiration in the Qinghai-Tibet Plateau, this study used the relevant literature in the China National Knowledge Infrastructure (CNKI) and the Web of Science Core Collection Database as data sources, based on bibliometric analysis methods, and used Citespace and VOSviewer. The research hotspots and research trends of soil respiration on the Qinghai-Tibet Plateau are summarized through analysis of domestic and foreign publication trends, high-frequency keyword co-occurrence analysis, and country, institution, and author cooperation network analysis. The results show that: (1) The research on soil respiration on the Qinghai-Tibet Plateau at home and abroad is increasing year by year, but the growth rate of foreign research is greater than that of domestic research. (2) The cooperation network on soil respiration on the Qinghai-Tibet Plateau at home and abroad is not very close, and the international cooperation network and author cooperation network need to be strengthened. (3) The research on soil respiration on the Qinghai-Tibet Plateau is roughly divided into three stages: the budding stage (1997-2005), the growth stage (2006-2013), and the rapid development stage (2014-present). in constant development. (5) The current research contents in the field of soil respiration mainly focus on Qinghai-Tibet Plateau soil respiration and global climate change, ecosystem respiration and global climate change, nitrogen addition and soil respiration, soil respiration and soil temperature, soil respiration and overgrazing. This study will summarize the research status and research trends of the Qinghai-Tibet Plateau, and provide information support for the research direction of soil respiration on the Qinghai-Tibet Plateau at home and abroad.
