[Objective] The impact of groundwater dynamics on the evolution of soil salinization and its mechanism were systematically investigated to provide a theoretical reference for the comprehensive treatment of saline-alkaline land. [Methods] Based on VOSviewer and Citespace visualization software, the relevant literature in the Web of Science core database (WoS) and China National Knowledge Infrastructure (CNKI) was used to analyse the number of articles issued and their countries and institution form. A quantitative and multivariate dynamic visualization analysis of domestic and international research in this field from 2000—2022 was carried out, starting from the amount, country institution and author of publications, and keyword clustering, and their changes over time. [Results] The research on the impact of groundwater dynamics on soil water salinity at home and abroad followed a fluctuating upward trend with China and the United States as the core, and the cooperation between China and the United States, Germany, Australia, and other countries was more closely linked. The core authors and institutions focused on the comprehensive utilization of saline-alkaline land and groundwater regulation, which has contributed greatly to the effective improvement of the quality of arable land. The English literature mainly covered the disciplines of water resources (26.18%) and environmental science and ecology (23.22%); the disciplines that accounted for the largest proportion of the Chinese literature were basic agricultural science (30.05%) and agronomy (27.76%). The focus has been gradually improved from single to diversified research and has been transformed from the basic theory of salinity to the comprehensive utilization of saline-alkaline land to improve quality and increase the efficiency of land use. Studies have actively responded to national strategic needs and have clarified the comprehensive utilization of saline-alkaline land to improve the quality of arable land. [Conclusion] This field is a hotspot for future research. Future research should focus on the following aspects: optimal allocation of water resources, establishment of a sound water resources development and management system, construction of a national cloud platform for comprehensive utilization of saline and alkaline land, strengthen the in-depth integration of information technology and water conservancy, and in-depth investigation of the mechanism of influence of groundwater regulation on the water and salt transport in the soil-air pocket. This research could provide new ideas and methods for the comprehensive utilization of saline land.
