摘 要:羊草草原是我国较具代表性的典型草原亚类,被认为是经济价值较高的天然牧场和割草场。受过度放牧和刈割等多因素的影响,羊草草原面临植被退化和生态系统恶化的严峻挑战。为了深入了解这一问题的研究现状,基于中国知网(CNKI)数据库,运用CiteSpace可视化软件对1994—2023年关于羊草草原相关研究进行可视化分析,旨在总结归纳羊草草原的研究热点和前沿趋势。结果表明,1994—2023年,研究焦点主要集中在羊草草原的退化成因、植被演替、恢复改良措施等方面,未来研究应更加关注不同恢复措施的效果评估和可持续性,为草原生态系统的保护和管理提供科学支持。Leymus chinensis grassland is a typical grassland subtype in China and is considered to be a natural pasture and mowing Grassland with high economic value.Affected by many factors such as overgrazing and cutting,L.chinensis grassland is facing severe challenges of vegetation degradation and ecosystem deterioration.In order to deeply understand the research status of this issue,this paper uses CiteSpace visualization software to visually analyze the related research on L.chinensis grassland from 1994 to 2023 based on the database of China National Knowledge Infrastructure(CNKI),in order to summarize the research hotspots and frontier trends of L.chinensis grassland.The results showed that from 1994 to 2023,the research focus mainly focused on the causes of degradation,vegetation succession,restoration and improvement measures of L.chinensis grassland.Future research should pay more attention to the effect evaluation and sustainability of different restoration measures,which provided scientific support for the protection and management of grassland ecosystem.
