Research Hotspots and Progress in Fungi and Carbon Cycle based on Bibliometrics Analysis

Using bibliometric analysis combined with CiteSpace and VOSviewer visualization tools, this study analyzed the literature related to fungi and carbon cycling in the WOS Core Collection database from 2013 to 2023. The aim was to explore the research hotspots and provide theoretical references for understanding the research directions in this field over the past decade. The results indicated a gradual upward trend in the number of publications in this field, indicating broad development prospects. China had the largest number of publications, but Germany had the highest centrality. The Chinese Academy of Sciences was the research institution with the largest number of publications and the highest centrality, indicating its strong comprehensive research strength in the field of fungal carbon cycle research. Through co-occurrence, burst, and clustering analysis of keywords, it was found that current research hotspots focused on mycorrhizal fungi, microbial communities, soil organic matter, climate change, and biomass. Overall, fungal carbon cycle research had strong research prospects, but still faced significant challenges. The development trend of interdisciplinary and multi-research methods is needed to systematically study fungal carbon cycle research under global change.
