基于文献计量分析土壤无机碳研究现状与趋势

Bibliometric Analysis of the Status and Trends in Soil Inorganic Carbon Research

  • 摘要: 土壤无机碳在固碳、维持土壤质量、促进有机碳稳定性与肥力和生态系统服务功能等方面有重要作用。以Web of Science核心合集数据库和CNKI数据库中472篇土壤无机碳研究的文献为数据源,通过VOSviewer、CiteSpace和HistCite分别从发文量、被引频次、合作强度及关键词等角度对发文国家、机构、作者、研究热点及其变化趋势进行计量分析与可视化展示。结果表明:2003 ~ 2023 a期间土壤无机碳研究的发文数量不断增长,主要从土壤学与环境学向其他学科延伸;科研机构以中国科学院为首,而发文作者形成了以Kuzyakov Y为核心的作者群,总体而言我国的发文量和国际影响力最大。当前的研究热点集中在土壤无机碳储量及其影响因素,土壤无机碳在碳循环中的作用及其固碳潜力,土壤无机碳的生态系统服务功能等方面。然而,当前对碳酸盐再沉淀过程中有机碳向无机碳的转移及固碳作用研究不足,尤其是植物光合同化碳向土壤次生碳酸盐累积转化及对氮肥的响应机制尚不清楚。今后应通过实地研究收集无机碳数据并结合机器学习建模等方法,提高估算全球碳库及碳周转速率的准确性;深化土壤有机碳-二氧化碳-土壤无机碳的转化机理,进一步明晰无机碳对稳定土壤碳库和维持土壤健康等生态服务方面的作用。

     

    Abstract: Soil inorganic carbon(C)plays an important role in sequestering C, maintaining soil quality, promoting organic C stability and fertility and ecosystem service functions. Taking 472 documents of soil inorganic C research in Web of Science core ensemble database and CNKI database as the data source, we analyzed the results by using VOSviewer, CiteSpace and HistCite to measure and analyze the issuing countries, institutions, authors, research hotspots and their changing trends from the perspectives of issuing volume, citation frequency, intensity of cooperation and keywords, respectively. The results showed that the number of publications on soil inorganic C research has been increasing from 2003 to 2023, mainly from soil science and environmental science to other disciplines. The research institutions were led by the Chinese Academy of Sciences, and the authors of the publications have formed a group of authors with Kuzyakov Y as the core. The number of publications and the international influence of China was the largest. The current research hotspots focused on soil inorganic C storage and its influencing factors, the role of soil inorganic C in the C cycle and its sequestration potential, and the ecosystem service function of soil inorganic C. However, the transfer of organic C to inorganic C and C sequestration during carbonate redeposition was currently understudied, especially the conversion of plant photo-contracted C to soil secondary carbonate accumulation and the response mechanism to nitrogen fertilizer are still unclear. In the future, inorganic C data should be collected through field studies and combined with machine learning modeling to improve the accuracy of estimating the global C pool and the rate of C turnover; deepen the mechanism of soil organic C - CO2 - soil inorganic C conversion, and further clarify the role of inorganic C in stabilizing the soil C pool and maintaining soil health and other ecological services.
