Abstract

Abstract:

As a key ecological disturbance factor, fire disturbance significantly affects the reorganization and functional decline of soil fauna communities through direct thermal effects and indirect environmental changes, thereby perturbing belowground ecological processes. In order to systematically summarize the research progress on the impacts of fire disturbance on soil fauna and clarify the disciplinary development context and cutting-edge directions, this study took the literature on the impacts of fire disturbance on soil fauna published from 2000 to 2024 in the Web of Science database as the data source, and conducted a bibliometric analysis on the 296 retrieved literatures using CiteSpace software. The results showed that the annual number of publications in this field presented a trend of "slow development-rapid growth-explosive growth", reaching a peak of 30 in 2024. The research strength was mainly concentrated in 55 countries (regions) such as the United States, China, and Germany. Among them, the United States had published 77 articles (betweenness centrality 0.82 ), which is at the core dominance, and had formed an extensive cooperative network with China, Germany and other countries. China ranked the second in the world with 27 papers published, but the betweenness centrality was only 0.1, and international cooperation needed to be further strengthened. Keywords co-occurrence and cluster analysis showed that the research focus gradually shifted from the direct effect of fire disturbance to the succession of soil animal communities, the coupling mechanism of carbon cycle and the maintenance of ecosystem stability. Keyword burst analysis showed that "organic carbon" and "fire intensity" became the frontier directions after 2016. Against the background of climate change, it has great significance to conduct the research on ecological effects and recovery mechanisms of fire disturbance on soil fauna. Quantifying the nonlinear impacts of fire disturbance on soil fauna diversity, assessing the long-term effects of biodiversity loss on ecosystem services and constructing multi-scale community dynamic prediction models are likely to be the research priorities in the next few years.
