Abstract：To comprehensively analyze the status and emerging trends in grassland ecology research，this study employed the bibliometric tool CiteSpace to examine literature related to grassand ecology from the China National Knowledge Infrastructure（CNKI） database spanning the period from 2OOl to 2O23. The analysis is conducted across three dimensions：co-occurrence networks of authors，institutions，and keywords，complemented by visualizations ofburst terms and colaboration networks.The findings revealed a total of 21O8 publications on grassland ecosystems during this period，with key research areas focusing on ecological restoration， ecosystem services，ecological management，ecosystem protection，and species diversity. In recent years， grassland resource management，nitrogen addition efects，and the spatial organization of production，living， and ecological spaces have emergedas prominent research hotspots.The trajectory of grassland ecology researchreflects an increasing trend toward interdisciplinaryand inter-institutional colaboration，greater integration of macro-and micro-level studies，and a stronger emphasison blending technological inovation with practical applications.These results ofer valuable insights to guide future research and development in the field of grassland ecology.
