摘 要
盐渍化土壤是全球范围内面临的严重环境问题之一，它不仅降低了土地的利用效率，还严重影响了生态系统的健康和稳定。本研究围绕土壤改良剂在盐渍化土壤生态修复中的应用进行了深入探讨。本研究概述了土壤改良剂的种类与作用机理，并从理论层面探讨了其在改善盐渍化土壤理化性质及生物活性方面的潜力。合理选择和施用土壤改良剂可以有效改善盐渍化土壤的结构，提高其透气性和保水性，从而促进土壤生物活性的提升。然而，盐渍化土壤的生态修复仍面临诸多挑战，包括改良剂的选择与适配性、施用成本、长期效果与持续性问题等。对此，本研究提出了开发新型高效、低成本的改良剂，优化施用技术和模式，以及构建政策支持和激励机制等。土壤改良剂在盐渍化土壤生态修复中具有重要的应用价值，但需要科学规划和综合治理策略的支持，以实现土壤资源的可持续利用和生态环境的持续改善。

APPLICATION OF SOIL AMENDMENTS IN ECOLOGICAL RESTORATION OF SALINIZED SOIL
ABSTRACT
Salinized soil is one of the serious environmental problems in the world, which not only reduces the efficiency of land use, but also seriously affects the health and stability of ecosystem. The application of soil amendments in ecological restoration of salinized soil was discussed in this study. In this study, the types and mechanisms of soil amendments were summarized, and their potential in improving physical and chemical properties and biological activities of salinized soil was discussed theoretically. Reasonable selection and application of soil amendments can effectively improve the structure of salinized soil, improve its permeability and water retention, and promote the improvement of soil biological activity. However, the ecological restoration of salinized soil still faces many challenges, including the selection and suitability of amendments, application costs, long-term effects and sustainability issues. In this study, the development of new efficient and low-cost improvers, optimization of application techniques and models, and the construction of policy support and incentive mechanisms were proposed. Soil amendments have important application value in the ecological restoration of salinized soil, but it needs the support of scientific planning and comprehensive management strategy to realize the sustainable use of soil resources and the continuous improvement of ecological environment.
