盐碱地可持续利用及改良技术研究进展

Research Progress on Sustainable Utilization and Improvement Technology of Saline Alkali Land

土壤盐渍化问题是困扰耕地质量安全的土壤问题之一,在耕地面积不断减少、人口数量不断增长的压力下,盐碱地的开发利用与改良是保障粮食安全,促进农业可持续发展重要途径之一。本文系统地阐述了盐渍化土壤形成的原因;分别从物理、化学、生物方面阐述了盐碱地改良的研究成果;对盐碱地可持续利用进行综述。此外,展望了盐碱地改良的发展趋势,为盐渍化资源的开发、利用与改良等提供理论参考。

Soil salinization is one of the soil problems that perplexes the quality and safety of cultivated land. Under the pressure of decreasing cultivated land area and increasing population, the development, utilization and improvement of saline alkali land is one of the important ways to ensure food se-curity and promote agricultural sustainable development. In this paper, the reasons for the for-mation of salinized soil are systematically expounded;the research results of saline alkali soil im-provement are elaborated from the physical, chemical and biological aspects;the sustainable uti-lization of saline alkali land is summarized. In addition, the development trend of saline alkali land improvement is prospected, which provides theoretical reference for the development, utilization and improvement of salinization resources.
