【摘要】：生态系统服务是生态学研究的核心和热点议题。近年来,各国和各相关机构对生态系统服务的研究力度不断加大。基于SCI-E和CNKI数据库,利用文献计量方法,分析了国内外生态系统服务研究的发展特征和变化趋势。研究结果表明:(1)国内外生态系统服务研究的发文量不断增加,发展态势良好。(2)发达国家是生态系统服务领域的主要研究力量,美国占据绝对领先地位;美国的加利福尼亚大学是主要研究机构;总体来看,国家和机构间的合作正在不断增强。(3)当前该领域的8类研究热点分别是生态系统服务机理研究,保护管理及可持续性、生物多样性、脆弱性、土地利用及景观变化、评估与模型、气候变化、政策与决策分析。从各个时期国内外研究热点整体分布情况来看,国际更侧重于生态系统服务及生态系统服务与人类福祉的依存关系的研究,国内则更加关注生态系统服务评估。(4)近年来中国在生态系统服务研究领域的国际地位有所提升,科研产出量显著增加,累积发文量居世界第5位,中国科学院是全球主要研究机构之一,但论文被引频次相对偏低,国际合作亟待加强和提升。
[Abstract]:Ecosystem services are the core and hot topics of ecological research. In recent years, the research on ecosystem services has been increasing in various countries and related institutions. Based on SCI-E and CNKI database. The development characteristics and trends of ecosystem services research at home and abroad were analyzed by means of bibliometrics. The results showed that the number of papers on ecosystem services research at home and abroad was increasing. The developed countries are the main research force in the field of ecosystem services, and the United States occupies an absolute leading position; The University of California is the leading research institution in the United States; Overall, cooperation between countries and institutions is increasing. 3) the current eight types of research hotspots in this area are ecosystem service mechanism research, conservation management and sustainability, biodiversity, vulnerability. Land use and landscape change, assessment and model, climate change, policy and decision analysis. The international focus is more on ecosystem services and the interdependence of ecosystem services with human well-being. In recent years, China's international position in the field of ecosystem services research has increased, the volume of scientific research output has increased significantly, the cumulative volume of papers ranked fifth in the world. The Chinese Academy of Sciences is one of the major research institutions in the world, but the frequency of citation is relatively low, and international cooperation needs to be strengthened and promoted.

【正文快照】： 生态系统服务是指人类从生态系统获得的惠益[1]。随着人类改造自然能力的不断提高,人类活动对生态系统长期的压力和破坏导致生态系统服务能力受到严重削弱。人类当前面临的多种生态问题的本质是生态系统服务功能遭到破坏和退化[2-3]。尽管人类一直依赖于生态系统服务而得以生
