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 grassland ecology from the China National Knowledge Infrastructure （CNKI） database spanning the period from 2001 to 2023. The analysis is conducted across three dimensions： co-occurrence networks of authors， institutions， and keywords， complemented by visualizations of burst terms and collaboration networks. The findings revealed a total of 2108 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 effects， and the spatial organization of production， living， and ecological spaces have emerged as prominent research hotspots. The trajectory of grassland ecology research reflects an increasing trend toward interdisciplinary and inter-institutional collaboration， greater integration of macro-and micro-level studies， and a stronger emphasis on blending technological innovation with practical applications. These results offer valuable insights to guide future research and development in the field of grassland ecology.

摘要： 为了深入剖析草地生态研究的现状与前沿趋势，本文运用文献计量工具CiteSpace，以中国知网（CNKI）中2001—2023年的草地生态相关文献为数据源，从作者、机构、关键词等三个维度开展共现网络分析，并结合突变术语及合作网络进行可视化计量研究。结果显示，2001年至2023年间草地生态系统研究共发表文献2108篇，主要聚焦于生态恢复、生态服务功能、生态管理、生态系统保护以及物种多样性等领域。近年来，草地资源管理、氮添加效应和三生空间布局逐渐成为研究热点。研究发展呈现出跨学科与跨机构合作增强的趋势，逐步加强宏观与微观研究的结合，并重视技术创新与实践应用的融合，为未来草地生态研究提供了重要参考。
