Research on mountain ecosystem services (MES) under the influence of climate change and human activities has gradually become the focus of academic attention in recent years. Here, this study analyzes the research hotspots and frontiers of this field based on metrics including main research forces, core journals and papers, research hotspots and topics by using the methods of bibliometrics and text mining. The results revealed the following: (1) the number of papers is increasing rapidly in recent years. From 2015 to 2019, 929 papers were published, with an average of 185 papers per year. But the average cited times of those papers is declining, dropped from 6.01 in 2016 to 4.2 in 2019. The USA, UK, and China rank the top three of the number of papers. Univ Maryland, Univ Oxford and Univ Wisconsin have the greatest influence, with an average of more than 77 citations per paper; (2) The most cited journals are PNAS, WETLANDS, ECOLOGY, AND SOCIETY, which are cited 191.54, 53.91, and 40.00 respectively. Most papers were published in OA journals including SUSTAINABILITY, WATER, Forests since 2017. Ten core papers undertaking knowledge transfer in this field have been identified; (3) analysis of the keywords found a new trend of integration of natural science and humanities. In two development stages of 2000-2014 and 2015-2019, the research hotspots mainly focused on mountain water resources, forest resources, land resources and the impact of climate change and human activities, and there are obvious differences and characteristics in different stages. The hotspot worthy of attention in the near future is the assessment of mountain ecosystem services capacity and value. This is the first comprehensive visualization and analysis of the research hotspots and trends of mountain ecosystem services.
气候变化和人类活动影响下的山地生态系统服务研究近年来逐渐成为学术关注的焦点。本研究运用文献计量学和文本挖掘方法，分析了主要研究力量、核心期刊和论文、研究热点和主题等指标，探讨了该领域的研究热点和前沿。结果表明：（1）近年来论文数量呈快速增长趋势，2015-2019 年发表论文 929 篇，平均每年 185 篇，但论文平均被引频次呈下降趋势，由 2016 年的 6.01 下降至 2019 年的 4.2；发文量排名前三位的国家是美国、英国和中国，发文量排名前三位的机构是马里兰大学、牛津大学和威斯康星大学，单篇论文平均被引频次均超过 77 次；（2）被引频次最高的期刊是 PNAS、WETLANDS、ECOLOGY AND SOCIETY，分别为 191.54、53.91、40.00 次；发文量最多的期刊是 2017 年以来的 OA 期刊，包括 SUSTAINABILITY、WATER、Forests 等；共识别出 10 篇核心论文，承担了该领域的知识转移任务；（3）关键词分析发现，自然科学与人文科学融合的新趋势。在 2000-2014 年和 2015-2019 年两个发展阶段，研究热点主要集中在山地水资源、森林资源、土地资源以及气候变化和人类活动的影响，不同阶段存在明显差异和特征。近期值得关注的热点是山地生态系统服务能力和价值评估。这是对山地生态系统服务研究热点和趋势的首次全面可视化和分析。
