摘　　要：盐分是影响植物生长的一个重要环境因素。总结了盐分胁迫对植物生长发育影响的研究进展,从氧自由基产生、膜脂过氧化、离子伤害、渗透伤害和有毒物质积累等方面系统分析了盐胁迫对植物的伤害机理,并综述了植物对盐分胁迫的适应机制,总结了主要的抗盐生理指标。Salinity is a major environmental factor limiting plant growth. The paper summarized the research progress of the effects of salt stress on plant. Analysised the mechanism of the hurt to plant by salt stress, including the produce of free radical,the membrane lipid peroxidation,the hurt of inorganic ions,the hurt of infiltration and accumulation of toxicant .Expatiated the research on the mechanism of the resistance of the plant to salinity. The physiological factors of plant to salt stress been Summarized.
