[Objective] Grazing, as a major method of utilizing grassland resources, is an important driving factor affecting the interaction between plants and soil. A systematic understanding of the research hotspots and development trends related to the impact of grazing on plant-soil interaction in grassland ecosystems can provide valuable reference for the future direction of grassland ecology.[Methods] Based on R language, Citespace, and VOSviewer software, 10,809 articles from Web of Science and CNKI (China National Knowledge Infrastructure) databases published between 2000 and 2023 were analyzed.[Results] The overall publication volume in this field has shown an increasing trend. The research hotspots mainly focus on the impact of grazing management on vegetation community characteristics and soil cycling functions in climate-sensitive grassland areas. The research perspective has gradually shifted from traditional ecological investigations of plant communities, populations, and individual ecology under varying grazing intensities to exploring the complex mechanisms of grazing and climate change on grassland ecosystems. This has extended to studies on ecosystem regeneration, carbon balance characteristics, and ultimately to the development of ecosystem optimization management models based on multi-factor interactions. This shift marks a transition in grassland ecology research from macro-level to more detailed micro-level approaches.[Conclusion] Future research should draw on advanced methods from related fields and strengthen studies on the complex mechanisms of cross-scale, multi-model interactions on ecosystems. It is essential to integrate small-scale experimental results with regional or global ecological models and focus on the influence of multidimensional, multiscale, and multifactorial interactions on both aboveground and underground ecological processes to promote the optimization of ecosystem management and conservation strategies.
