CiteSpace Software Visualization Analyses of the Last Thirty Years of Research on Populus euphratica

Populus euphratica is the only tall tree species that adapts to desert environment. It has strong drought tolerance and subject of extreme concern at home abroad. After 30 years development, scope research on very extensive, but content not yet been crystalized into a mature field, directions abroad differ. In this study, we retrieved references ‘P. euphratica’ published from 1992 2022 in both China National Knowledge Infrastructure core journals database Web Science collection database, CiteSpace software was employed conduct keyword-centered bibliometric analysis spatial temporal dimensions. The purpose study clarify areas, developmental changes, differences between domestic international priorities last years, future trends field P. research. results show there were 1619 papers related research, while 656 foreign same field. development went through three stages initiation (1992–2000), growth (2001–2008) stability (2009–2021), whereas no significant trend change observed. disciplines focus biology, focuses crop science. terms content, sustainable uses forests their response drought, intending improve ecosystems.
