Soil salinization, exacerbated by climate change, poses significant threats to agricultural productivity, land restoration, and ecosystem resilience. This study reviews current knowledge on plant-soil interactions as a strategy to mitigate soil salinization induced by climate change, focusing on their role in soil salinity dynamics and tolerance mechanisms. The review examines how alterations in hydrological and temperature regimes impact soil salinity and how plant-soil mechanisms-such as salt exclusion, compartmentalization, and plant-microbe interactions-contribute to salinity mitigation. This, in turn, enhances soil quality, fertility, microbial diversity, and ecosystem services. The analysis identifies a growing body of research and highlights key themes and emerging trends, including drought, microbial communities, and salt tolerance strategies. This study underscores the critical role of plant-soil interactions in sustainable salinity management and identifies knowledge gaps and future research priorities, advocating for plant-soil interactions as a crucial pathway for improving ecosystem resilience to salinity stress amid climate change.
土壤盐渍化因气候变化而加剧，对农业生产力、土地恢复和生态系统恢复力构成重大威胁。本研究回顾了关于植物 - 土壤相互作用的现有知识，将其作为缓解气候变化引起的土壤盐渍化的一种策略，重点关注它们在土壤盐分动态和耐受机制中的作用。该综述探讨了水文和温度状况的变化如何影响土壤盐分，以及植物 - 土壤机制（如盐分排斥、区室化和植物 - 微生物相互作用）如何有助于减轻盐分。反过来，这又提高了土壤质量、肥力、微生物多样性和生态系统服务。分析确定了越来越多的研究，并突出了关键主题和新出现的趋势，包括干旱、微生物群落和耐盐策略。本研究强调了植物 - 土壤相互作用在可持续盐分管理中的关键作用，确定了知识空白和未来研究重点，倡导将植物 - 土壤相互作用作为提高生态系统在气候变化下对盐分胁迫恢复力的关键途径。
