【摘要】 植被的固碳效益是有效应对空气二氧化碳浓度增加的重要措施。本研究基于文献计量软件Citespace5.2对1999～2019年的WOS核心合集5085篇文献进行分析,获得相关研究的时空分布,研究热点历程以及对未来的研究趋势进行预测。结果表明:①在时间特征上,该领域研究数量呈逐年上升趋势,近年来文献的联系比之前更加紧密;②在空间分布特征上,该研究分布在多个国家和地区,美国在研究数量和质量上都较强,并形成独立的研究体系,全球范围内形成美国、中国、欧洲国家为中心的主要研究区域;③该领域的研究热点经历了从较少数量的植物固碳效益研究到土壤为主,植物为辅的研究阶段,再到植物固碳与土壤固碳共同应对气候变化的动态发展过程。④未来的研究趋势仍集中土壤和植被的动态变化对减缓气候变暖的意义。更多还原

【Abstract】 The carbon sequestration of vegetation is an important measure to deal with the increasing of carbon dioxide effectively.Based on Citespace5.2,a bibliometric software,this study analyzed 5,085 paper in WOS core collections from 1999 to 2019,and obtained the spatiotenporal distribution of related studies,the evolution of research hotspots,and predicted the future research trends. The results show that ① in terms of time characteristics,the number of studies in this field is increasing year by year,and the literature is more closely related than before in recent years;② in terms of spatial distribution characteristics,the research distributed in many countries and regions.The United States has a higher research quantity and quality,having been forming an independent research system.Furthermore the main research areas centered on the United States,China and European countries globally;③ research hotspots in this field have experienced a dynamic development process from a small number of studies on the benefits of vegetation carbon sequestration to a stage in which soil is the main research and plants are the auxiliary researching,and then turn to the joint response of vegetation carbon sequestration and soil carbon sequestration to climate changing.④ future research trends still focus on the significance of dynamic changes in soil and vegetation in mitigating climate warming.更多还原
