Salinization was one of the major abiotic stresses in the world limiting crop growth and yield. Phytohormone salicylic acid （SA） played an important role in regulating plant growth, development and against stress. This paper reviewed the synthesis and metabolic pathway of SA in plants, factors influencing the effectiveness of SA, and the physiological mechanism of SA in regulating plant salt tolerance. The physiological mechanism that SA alleviated salt stress including five aspects： enhancing antioxidant defense system and scavenging reactive oxygen species, improving photosynthesis and respiration, regulating ion uptake and distribution, and mitigating ion toxicity, regulating material metabolism and improving nutritional status, cross-talking with other hormones or signaling molecule. Several questions to be resolved in future were
