Abstract: The comprehensive management of saline-alkali land is of great significance to ensure food security,improve the efficiency of land resource utilization and realize the sustainable development of agriculture in China.In this study,the bibliometric method was used to analyze the current research situation of comprehensive management of saline-alkali land.The results show that the research in the field of global comprehensive management of saline-alkali land is on the rise,and the research in this field in China started relatively early,and the number of papers published and the number of institutions have significant advantages,and in recent years,a research institution with sustainable academic output has been formed,but there is still room for improvement in research quality and international exchange and cooperation.The research hotspots focus on crop salinity-alkali tolerance,traditional saline-alkali land improvement measures,biochar remediation,and microbial remediation.In this study,we put forward suggestions that China should strengthen interdisciplinary integration,effectively improve the quality of scientific research,improve the mechanism of achievement transformation,strengthen international exchanges and cooperation,and pay attention to hot frontiers,in order to provide support for the research on comprehensive management of saline-alkali land in China.
