摘　　要：【目的】统计分析国内干旱瘠薄地研究的热点,为旱地农业的高效发展和科研人员及时掌握干旱瘠薄地的研究态势提供参考。【方法】参考文献计量学方法,分析1955—2023年CNKI数据库中收录的相关研究文献,对国内干旱瘠薄地研究的论文数量、出版刊物、研究内容和研究重点等进行统计,并用CiteSpace V可视化软件进行研究热点预测和分析。【结果】1955—2023年干旱瘠薄地论文数量整体呈波浪式上升,其相关研究逐渐成为研究热点。目前,国内发文机构主要集中在农业发展水平较高、学术力量雄厚的省份,如北京、江苏、四川、河南和陕西等地,其中,西北农林科技大学的发文量最多,达92篇,且相关论文主要发表在环境和农业类学术期刊。检索获得的2116篇论文和高水平822篇论文中发文量在4篇及以上的作者分别有34人和15人,共发表论文分别为226篇和95篇,分别占干旱瘠薄地相关论文总数的10.7%和11.6%,与普赖斯推论的指标(核心作者的论文数应占论文总数的50%)尚存在差距,没有稳定的核心作者群体,核心作者人数较少。高频关键词主要有干旱胁迫、土壤退化、抗旱性、小麦、花生和光合特性等,且不同阶段研究重点和热点不同。【结论】干旱瘠薄地不同时间段的研究重点和热点不同。加强国内外干旱瘠薄地研究领域高水平科研机构间的合作与交流是提高科研成果产出的有效途径之一,研究干旱瘠薄地作物对干旱胁迫生理及分子水平的响应机理,选育抗旱性强的作物品种,改良干旱瘠薄地的水肥供应,从而提高作物产量已成为当前干旱瘠薄地研究的重点和热点。【Objective】The hotspots about research on dry and barren land in China were studied and analyzed,which provided reference for the efficient development of dryland agriculture and timely grasp of the research situation of arid and barren land.【Method】Based on bibliometrics methods,the relative studies collected by CNKI from 1955 to 2023 were analyzed,the number of papers,publications,research contents,hotspots in China were recorded,and the research hotspots were predicted and analyzed through CiteSpace V.【Result】The literature about arid and dry land from 1955 to 2023 showed a fluctuant-rising trend,and the relative studies has gradually become the hotspots.At present,domestic publishing institutions are mainly concentrated in provinces with high agricultural development level and strong academic ability,such as Beijing,Jiangsu,Sichuan,Henan and Shaanxi,among which Northwest A&F University has the largest number of publications,reaching 92,and related papers are mainly published in environmental and agricultural academic journals.There are 34 and 15 authors who published paper and published 4 or more papers from the obtained 2116 papers and 822 high-level papers through retrieving,with 226 and 95 papers published respectively,accounting for 10.7%and 11.6%of the total number of papers related to arid and barren land,respectively,which is still far from the index inferred by Price(the number of papers by core authors should account for 50%of the total number of papers).There is no stable core author group and fewer core authors.The high frequency keywords mainly include drought stress,soil degradation,drought resistance,wheat,peanut and photosynthetic characteristics,and the research focus and hotspots are different at different stages.【Conclusion】The study key points and hotspots of arid and dry land are different in different periods.Strengthening the cooperation and exchange of high-level scientific research institutions in the field of research about arid and barren land at home and abroad is on
