摘　　要：以中国知网(CNKI)和web of Science(WOS)数据库中检索到的2000—2022年有关改良盐碱地研究的1 329篇核心期刊文献为数据源,运用数据可视化软件,定性定量地进行聚类、热点、共现、语义网络等分析,从植物改良盐碱地的研究趋势、研究热点以及改良效果等角度阐明了国内外植物改良盐碱地的现状。结果表明,盐碱地研究的文献数量呈逐年上升趋势,植物改良盐碱地的效果是目前的热点研究问题。草本是盐碱地改良中最常用的植物,则灌木和乔木主要有15种。种植植物主要可以降低盐碱地的土壤pH值、含盐量和盐基离子浓度,改善土壤物理特征,提高土壤肥力水平。不同植物针对盐碱地的改良效果均有差异,建立盐碱植物库作为改良盐碱地的依据,这是该领域未来研究的重点,以现有研究为基础综述盐碱地改良的进展,对后续开展盐碱地的生态恢复和可持续发展具有指导意义。Taking 1329 core journal articles on the researches on saline-alkali soil improvement with plants from 2000 to 2022 retrieved in CNKI and Web of Science(WOS)databases as the data source,the data visualization software was used to qualitatively and quantitatively analyze the clustering,hot spots,co-occurrence,semantic network and other presence,and the current situation of plant improvement saline-alkali land at home and abroad was clarified from the perspectives of research trends,research hotspots and improvement effects of plant improvement saline-alkali land.The results show that the number of literature on saline-alkali land research is increasing year by year,and the effect of plants on improving saline-alkali land is a hot research problem.Herbaceous plants are the most commonly used plants in saline-alkali land improvement,and there are mainly 15 species of shrubs and trees.Planting plants can mainly reduce soil pH,salt content and salt ion concentration in saline-alkali land,improve soil physical characteristics,and increase soil fertility level.The improvement effect of different plants on saline-alkali land is different,and the establishment of saline-alkali plant bank as the basis for improving saline-alkali land is the focus of future research in this field,and the progress of saline-alkali land improvement is reviewed based on existing research,which has guiding significance for the subsequent ecological restoration and sustainable development of saline-alkali land.
