易分解有机碳输入量对武夷山不同林型土壤激发效应的影响

凋落物是植物同化碳的重要产物，是土壤有机碳库的主要来源。为系统了解凋落物分解对土壤碳库影响的研究进展，基于中国知网数据库（CNKI）和Web of Science（WOS）核心合集数据源，利用CiteSpace和VOSviewer文献可视化分析工具，从发文趋势、合作关系（团队、机构、国家）和期刊影响力等方面，对1989-2022年的相关文章进行计量分析。结果表明：国内和国际发文量总体呈增长态势。我国在该领域研究中发文量仅次于美国，占全球发文量的27.8％，表明我国研究者对该领域的研究有重要贡献，但整体影响力低于欧美发达国家（地区），美国和法国综合影响力最高，英国和瑞士论文篇均被引较高。凋落物分解、有机质、气候变化、碳循环和碳储量等关键词是该领域近年来的热点研究主题。未来我国应继续加强国际间合作研究，侧重凋落物分解相关特性对气候变化的响应和对环境污染的研究，提高我国在该领域的研究水平，将研究成果及时转化到碳减排增汇的研究中。

Leaf decomposition in two semi-evergreen tropical forests: influence of litter quality

As the main product of plant carbon assimilation, litter is an important source of soil organic carbon pool. Based on the data of CNKI and WOS from 1989 to 2022, the author used CiteSpace and VOSviewer to visualize the literature about publication trends, partnerships between teams, institutions and countries, and journal influence for a systematically understanding of the effects of litter decomposition on soil carbon pools. This paper concludes that domestic and international articles published in this field have a rising tendency, this paper concludes that domestic and international articles published in this field have a rising tendency. China ranks the second only to the USA, accounting for 27.8% of global publications, indicating that Chinese researchers have made important contributions to research in this field, but the overall impact is lower than that of developed countries of Europe and the United States. America and France have the highest integrated influence and Britain and Switzerland have higher citations. The keywords, such as litter decomposition, organic matter, climate change, carbon cycle, and carbon storage, are the hotspot research themes in this field in recent years. International cooperation should be strengthened in the future, and China should focus on the response of litter decomposition characteristics to climate change and environmental pollution, improve the research level, and timely transform the research results into the study of carbon emission reduction and carbon sinks enhancement.
