摘要: 近年来,草地碳汇研究备受关注,相关研究成果层出不穷。本文基于Web of Science核心合集,利用文献计量学评估了全球草地碳汇研究趋势和重点。研究发现,过去三十年间草地碳汇的研究热点由草地固碳潜力评估与高浓度CO2对植物与土壤有机碳的影响,转变到土地利用和管理方式对草地碳和氮储量的影响以及植物群落对碳循环影响的研究,最后聚焦到有机碳与气候变化对草地碳汇影响的研究。“氮”“固存”“动态”“碳”“草地”和“管理”等词汇是草地碳汇研究中的高频关键词,近年的研究热点词汇是“有机碳”“气候变化”和“黄土高原”。基于当前研究结果,建议在评估草地碳汇潜力时,充分考虑气候变化、土地利用、管理制度的相互作用;加强大尺度时空监测,全面评估草地碳汇特征;深入研究气候变化与非生物过程对草地碳汇的调控,为草地恢复与缓解措施提供理论支持。

Abstract: In recent years,research on grassland carbon sinks has attracted much attention,and related research results have emerged. This paper assessed global research trends and priorities on grassland carbon sinks using bibliometrics based on the Web of Science Core Collection. The study found that the research focus on grassland carbon sinks had changed over the past three decades,from assessing the carbon sequestration potential of grasslands and the effects of high CO2 concentrations on plant and soil organic carbon,to the effects of land use and management practices on carbon and nitrogen storage of grasslands and the effects of plant communities on the carbon cycle. Finally,the study focused on the effects of organic carbon and climate change on grassland carbon sinks. Terms such as nitrogen,sequestration,dynamics,carbon,grassland and management were high-frequency keywords in the study of grassland carbon sinks,and hot research terms in recent years were organic carbon,climate change and the Loess Plateau. Based on the results of the current study,it was recommended fully considering the interaction of climate change,land use and management systems when assessing the potential of grassland carbon sinks;strengthening large-scale spatial and temporal monitoring to comprehensively assess the characteristics of grassland carbon sinks;and conducting in-depth research on the regulation of grassland carbon sinks by climate change and abiotic processes to provide theoretical support for grassland restoration and mitigation measures.

Key words: Bibliometric analysis, Carbon sink, Climate change, Grassland
