摘　　要：利用脱硫石膏改良盐碱土,既开辟了脱硫石膏资源化利用的新途径,又为盐碱土改良提供了新方法。该文回顾了利用脱硫石膏改良盐碱土技术的起源及20多年发展历程,系统总结了脱硫石膏改良盐碱土基础理论、关键技术、短期和长期效应、环境安全性及产业化应用实践,针对目前国内外相关研究存在的问题和大面积应用过程中面临的难题,展望了该项技术研究。为了更好地利用脱硫石膏对我国大面积盐碱土进行高效安全治理,建议降低单位土地面积脱硫石膏施用量、增加长期定位试验点位和制定脱硫石膏农业应用的国家标准。The application of flue gas desulfurization(FGD) gypsum to ameliorate saline-alkaline soils not only provides a new use for FGD gypsum, but also provides a new method for improving saline-alkaline soils. This paper reviews the development of this technology for ameliorating saline-alkaline soils over the past 20 years including the basic theory, key technologies, short and long-term effects, environmental safety and industrialized applications of treating saline-alkaline soils with FGD gypsum. This paper also presents the future research needs to address current problems for large-scale applications. Efficient and safe treatments of large saline-alkaline soil areas using FGD gypsum should reduce the application rate of FGD gypsum per unit land area, increase long-term positioning of test points and formulate national standards for agricultural application of FGD gypsum.
