摘　　要：豆科植物沙冬青是中国西北方荒漠地区特有的超旱生常绿阔叶灌木,所处生态环境十分恶劣, 抗逆性非常强,被列为珍稀濒危保护植物。对沙冬青的抗逆性作了综述,从抗旱、抗寒、耐盐和抗风沙等 4个方面,对其研究进展进行了总结和探讨,分析了沙冬青能在逆境中得以生存的原因及其适应恶劣环 境的机理,并对其开发应用前景作了进一步讨论分析。Ammopiptanthus mongolicus （Maxim.） Cheng f., endemic to the semi-arid desert region of northwest China, is a rare and endangered evergreen leguminous shrub. Due to its long growth in a terribly atrocious entironment, it has a very strong resistant capability. The mechanism of drought, freezing, salt and sand stress tolerant capabilities that make A. mongolicus survive in the extreme adverse circumstances and the harsh reasons that the species could head adapted to was analyzed. The great value and usable prospect of A.mongolicus were proposed.
