Soil salinization is a critical land degradation process threatening global agricultural sustainability and food security. Under the intensifying context of global climate change, rising temperatures, altered precipitation patterns, sea?level rise, and an increased frequency of extreme climatic events significantly affect the balance of water and salt transport, thereby accelerating the rate and severity of soil salinization. This paper systematically reviews the interaction mechanisms between climate change factors and soil salinization processes, and analyzes the new challenges and opportunities that these changes pose for both traditional and emerging amelioration techniques. Emphasis is placed on research progress in various technical approaches, including physical measures, amendment application, bioremediation, land management, and precise water?salt regulation. The applicability, limitations, and synergistic potential of these techniques under climate change scenarios are critically examined. The results indicate that single?technique approaches are insufficient to address the multifaceted impacts of climate change, and that synergistic application of multiple techniques, tailored to local conditions, is key to improving remediation efficacy. Future research should strengthen the construction of long?term observation networks and data?sharing platforms, promote life?cycle assessment of amelioration techniques, develop machine?learning?based salt prediction and intelligent decision?making systems, and establish coupled climate?salinization?socioeconomic models. These efforts aim to provide scientific support for enhancing the productivity and ecological resilience of saline?alkali soils and ensuring regional sustainable development.
