摘要
基于Web of Science(WoS)核心合集和中国知网(CNKI)数据库,借助可视化软件,采用文献计量学方法,对1980—2021年蒙古高原土地沙漠化研究领域的文献进行了分析。结果表明:(1)发文数量由1980年的2篇增长至2021年的96篇,其变化经历了缓慢增长-波动式增长-快速增长过程;2000年后英文文献占主导,作者单位以中国科学院为主,与美国的合作最多。(2)2000年之前对土地沙漠化过程的关注度最高,之后土地沙漠化成因成为研究热点,近10 a沙漠化土地的生态修复成为主题。2000年之前研究主要集中在内蒙古沙地地区,21世纪后扩展到以农牧交错带为主的中国北方地区,2011—2021年聚焦在中国北方草原地区。(3)1980—2000年关注土地沙漠化概念、土地沙漠化成因及防治对策,进入21世纪后转变为土地沙漠化环境效应研究,2017—2021年则聚焦于沙漠化土地生态系统服务、生态修复研究,也是主要的研究趋势之一。今后的研究力求辐射蒙古高原整体,实现多源数据的高度融合,提高所获信息的精确度,以促进蒙古高原沙漠化土地生态功能的提升及中国北方生态屏障建设进程。
This paper employs the Web of Science(WoS)Core Collection and the CNKI database to conduct a comprehensive analysis of desertification research on the Mongolian Plateau spanning the years 1980 to 2021.Using visualization software and bibliometric methods,this study reveals notable trends and shifts in the scholarly landscape.Key findings include the following:(1)A discernible increase in publications,rising from an average of 2 per year in 1980 to 96 in 2021,delineating a trajectory of gradual to fluctuating to rapid growth.Post-2000,English literature predominated,with authors affiliated predominantly with the Chinese Academy of Sciences.The United States emerged as a primary collaborator.(2)The thematic focus evolved over time,with early attention on land desertification processes until 2000.Subsequently,research intensified on the causes of land desertification.The last decade saw a thematic shift toward ecological restoration of desertified land,with a particular emphasis on the sandy areas of Inner Mongolia before 2000.In the 21st century,this focus expanded to the northern regions of China,primarily within the agricultural-pastoral ecotone.Notably,the research spotlight shifted to the grassland areas of northern China during 2011—2021.(3)Research trajectories delineate a progression from the exploration of the concept and causes of land desertification,along with prevention and control strategies during 1980—2000.Subsequently,attention has shifted to the environmental effects of land desertification in the 21st century.The period of 2017—2021 witnessed a surge in studies investigating ecosystem services and the restoration of desertified land,emerging as a prominent research theme.Considering these insights,future research directions should pivot toward a holistic examination of the Mongolian Plateau,emphasizing the integration of multisource data to enhance information accuracy.This approach is vital for advancing the ecological functions of desertified land on the Mongolian Plateau and contributing
