基于文献计量法的草地退化研究进展分析与展望

Analysis and Prospect of the Research Progress of Grassland Degradation Based on Bibliometrics

草地是地球陆地生态系统的重要组成部分之一.草地退化问题制约着区域环境改善、资源高效利用和社会经济发展.基于CNKI数据库中1992—2020年的核心期刊文献进行检索,查阅1 556篇有关草地退化研究的相关文献,利用文献计量和CiteSpace科学知识图谱工具,对发文量、研究作者、研究机构、关键词聚类、时区图和突现词等可视化图谱进行分析.结果显示,草地退化的研究历程可划分为3个阶段:缓慢发展期(1992—2002年)、快速增长期(2003—2011年)和稳定发展期(2012—2020年),每个阶段的研究内容各有侧重.草地退化发文期刊与研究机构的集中度较高,并初步构建了研究合作网络.草地退化研究内容主要集中在群落特征、发生机制、恢复重建、土壤变化、可持续发展和气候变化方面.最后,结合当前国土空间生态修复、应对气候变化与实现“碳中和”目标展望了草地退化未来研究发展趋势.

Grassland is one of the important components of the earth’s terrestrial ecosystem.Grassland degradation restricts regional environmental improvement, resource utilization and socio-economic development.After searching the data of core journals from 1992 to 2020 in the CNKI database, and consulting 1 556 related literatures on grassland degradation, analyzed the visualization maps such as the number of the articles published, research authors, research institutions, keywords clusters, time zone diagrams and burst words based on bibliometrics and CiteSpace’s scientific knowledge map tools.The result shows that the research process of grassland degradation can be divided into three stages: the slow-speed development period(1992-2002),the high-speed growth period(2003-2011) and the stable development period(2012-2020),whose research content has its own respective focus.The publications of grassland degradation show a relatively high concentration, and a research cooperation network has initially been established.The research content of grassland degradation mainly focuses on community characteristics, occurrence mechanism, restoration and reconstruction, soil change, sustainable development and climate change.Finally, combining the current ecological restoration of territorial space, coping with climate change and achieving the goal of “carbon neutral”,he future research of grassland degradation is prospected.
