Grassland degradation has become a global social-ecological problem, which seriously limits the sustainability of indigenous people's livelihoods. Bibliometrics, a type of analysis based on the Science Citation Index-Expanded (SCI-E), was therefore performed to explore the research trends and focus areas of studies on sustainable livelihoods (SLs). We conducted an in-depth analysis of 489 research publications and their 25,144 references from 1991 to 2020. The results show that only few papers have been published, but the number of countries and research institutions involved shows an overall imbalance. We identified eight main clusters based on keyword co-occurrence, these being studies the content of which is an important representation of current research directions in this topic. The document co-citation analysis revealed 10 research clusters, representing the frontiers of research. Clusters included the following topics: NPP (Net Primary Productivity) dynamics, global change, ecological restoration, risk indicators, livelihood strategies, smallholder systems, drought relief, sustainable land management and common pool resources. We reviewed and interpreted these clusters in depth with a view to provide an up-to-date account of the dynamics of this research. As the first scientometric evaluation of research on sustainable livelihoods in grassland ecosystems, this study provides several theoretical and practical implications for global poverty eradication research, which are of great scientific value for global sustainable development.
草原退化已成为一个全球性的社会生态问题，严重限制了原住民生计的可持续性。因此，基于科学引文索引扩展版（SCI-E）进行了文献计量分析，以探究可持续生计研究的趋势和重点领域。我们对1991年至2020年的489篇研究出版物及其25144条参考文献进行了深入分析。结果表明，相关论文发表数量较少，但涉及的国家和研究机构数量总体上存在不平衡。我们基于关键词共现确定了八个主要聚类，这些聚类的研究内容是该主题当前研究方向的重要体现。文献共被引分析揭示了10个研究聚类，代表了研究前沿。聚类包括以下主题：净初级生产力（NPP）动态、全球变化、生态恢复、风险指标、生计策略、小农系统、抗旱救灾、可持续土地管理和公共池塘资源。我们对这些聚类进行了深入回顾和解读，以期对该研究的动态提供最新说明。作为对草原生态系统可持续生计研究的首次科学计量评估，本研究为全球消除贫困研究提供了若干理论和实践启示，对全球可持续发展具有重要科学价值。
