基于文献计量的根际激发效应研究进展与趋势

Research Progress and Trend Analysis of Rhizosphere Priming Effect Based on Bibliometrics Method

  • 摘要: 为了解根际激发效应(RPE)的研究进展和趋势,以Web of Science核心合集数据库中216篇RPE的研究论文为数据源,通过CiteSpace、VOS viewer对发文数量、平均/总被引频次及国家、机构、作者等进行了分析。结果表明:RPE研究大致可分为三个阶段:初始期(1984 ~ 1995年)、稳定发展期(1996 ~ 2014年)和快速增长期(2015 ~ 2022年)。美国总发文第一且中介中心性最高,国际影响力最大;中国在2018年后年均发文攀升至第一,在国际影响力方面次于德国,排在第三位。国际上主要以Cheng W、Kuzyakov Y为代表的核心作者群;就研究机构而言,中国科学院发文数量最多。研究热点主要集中在RPE的量化方法、影响因素及调控机制,且大多是采用植物幼苗和在室内盆栽条件下完成的。因此,亟需将室内研究拓展至野外原位条件,综合考虑全球气候变化的影响,改进CO2同位素示踪技术和捕获方法,加强成年树种RPE的种间差异变幅研究,优化Earth-System模型参数,进而准确估算陆地生态系统碳循环对气候变化的响应。

     

    Abstract: In order to understand the research progress and trend of rhizosphere priming effect(RPE), 216 research papers on RPE in Web of Science core collection database were used as data sources. The number of published papers, total/average citation frequency, countries, institutions and authors were analyzed by CiteSpace and VOS viewer. The results showed that the research on RPE could be divided into three stages: the preliminary stage (1984-1995), stable development stage (1996-2014) and rapid growth stage (2015-2022). The USA has the largest total number of publications, the highest intermediary centrality and the largest international influence. The average annual number of publications of China has climbed to the first after 2018, but ranking the third in the international influence by following Germany. At present, Cheng W and Kuzyakov Y are the main core authors. Chinese Academy of Sciences has the largest number of publications. The research hotspots mainly focus on the quantitative methods, influencing factors and regulatory mechanisms of RPE, and most of them are completed by plant seedlings and indoor potted conditions. Therefore, it is urgent to expand the indoor research to the in-situ field conditions, comprehensively consider the impact of global climate change, improve the CO2 isotope tracing technique and capture method, strengthen the research on the variation of RPE among adult tree species, optimize the parameters of Earth-System model, and then accurately estimate the response of terrestrial ecosystem carbon cycle to climate change.
