Bibliometric Analysis of Research Progress on Earthworms Affecting Transformation of Soil Organic Carbon

doi:10.11924/j.issn.1000-6850.casb2025-0297

Abstract

Abstract:

This study aims to systematically elaborate, through bibliometric analysis, the research progress and development trends in the field of earthworm-mediated SOC transformation and accumulation, thereby providing a basis for better understanding and addressing the challenge of the “earthworm dilemma.” Using the Web of Science Core Collection and CNKI databases as data sources, we conducted quantitative analysis and visual presentation of relevant literature with VOSviewer, CiteSpace, and HistCite, focusing on multiple dimensions including annual publication trends, citation frequency, disciplinary distribution, international collaboration networks, author/institutional cooperation, journal distribution, and research hotspots. In the research field of earthworm effects on SOC transformation, the number of publications has shown a steady growth trend, with agricultural science and environmental science as the main disciplines, extending to other fields. The current research hotspots mainly focus on: (1) the impact of interactions between soil emerging pollutants (e.g., microplastics) and earthworms on SOC transformation; (2) the effects of earthworms on greenhouse gas emissions; (3) the bidirectional mechanisms by which earthworms influence SOC transformation and stabilization. Future studies should strengthen multi-technology integration and long-term field experiments to uncover the regulatory mechanisms of earthworms on carbon cycling, establish quantitative models, and assess their interactions with agricultural management, thereby supporting carbon neutrality and soil health.

Key words: soil organic carbon, earthworms, bibliometrics, research progress, future trends
