摘　　要：荒漠化是威胁人类环境和生存的重大问题,自1977年内罗毕荒漠化会议以来得到了广泛的关注。本文基于WOS(web of science)数据库,利用Citespace软件技术,对全球荒漠化文献进行了整理和分析。结果显示:1992—2018年,荒漠化研究论文数量显示逐年增长态势,并涉及到环境科学、生态学、地球科学等107个学科,中国在该领域发表论文数量大幅领先(占37.34%),并与许多国家建立合作关系。荒漠化研究的高频关键词依次为沙漠化、土地退化、土壤侵蚀、风蚀等。对高频关键词沙漠化进行了案例研究,发现近年来沙漠化引起的沙尘气溶胶在全球变化中的作用备受关注;采取多学科交叉的方法研究沙漠化的驱动、反馈和影响是未来研究的重要方向。Desertification is one of the major issues threatening the human environment and survival. It has received widespread attention since the Nairobi Desertification Conference in 1977. Based on the WOS database and Citespace,this paper collates and analyzes the global desertification literation. The results show that from1992 to 2018,the number of research papers on desertification shows an increasing trend year by year,and involves 107 disciplines such as environmental science,ecology,and earth science. China is far ahead in the number of papers published in this field(accounting for 37.34%),and has established cooperative relations with many countries. Desertification research hotpots are sandy desertification,land degradation,soil erosion,wind erosion and so on. A case study of high-frequency keywords sandy desertification is carried out. It is found that the role of sand dust aerosols caused by desertification in global change has attracted much attention in recent years. Taking a multidisciplinary approach to study the drivers,feedbacks and impacts of desertification is one of the important directions for future research.
