Abstract: 【Objective】 To reveal the development status and research trend of saline-alkali land field.【Methods】 Using the literature on the field of saline-alkali land in the Web of Science core database from 2007 to 2017 as the data source,the method of bibliometrics was used to statistically analyze the number of publications,countries,institutions,and journals in the field of saline-alkali land in the past 10 years. The scientific knowledge map VOSviewer software was used to visually analyze the national cooperation,institutional cooperation,author cooperation,keyword clustering and emerging topics of the literature,and divided the research direction of the saline-alkali land field from the macro level.【Results】 The number of papers on the field of saline-alkali land had been growing rapidly year by year,the largest number of the papers in the journal INORGANIC CHEMISTRY,formed a collaborative network with HILL MICHAEL S,LI WENJUN and WESTERHAUSEN MATTHIAS as the core authors. The institution with the most scientific research results is the Chinese Academy of Sciences,and had formed a research group centered on the United States,China,and Germany. The hot keywords in the past 10 years were crystal-structure,complexes,water,calcium,alkaline-earth etc.,and the emerging keywords in the past 5 years were biomass,reactivity,kinetics,pyrolysis,performance etc.. 【Conclusion】 The research situation on the field of saline-alkali land in the past 10 years was in the growth stage.
