Abstract: In order to make an overall analysis on crop selenium speciation study, with the theme of crop selenium speciation research, 129 related literature from two decades (2001—2020) were retrieved from the Web of Science core collection database, and the sample was analyzed for data mining by using CiteSpace software. The results showed that the number of papers on crop selenium speciation research was small but showed a rapid growth trend. China was in a leading position in this research field but had fewer exchanges with other countries, and the communication between domestic research institutions needed to be strengthened, too. This researchinvolved many subject areas, such as selenium biofortification, phytoremediation, selenium fertilizer and so on. Crop selenium speciation study was summarized by using mapping knowledge domain to provide ideas and directions for other researchers.
