摘　　要：沙冬青是我国西北特有的高抗逆性灌木,是第三代古地中海沿岸植物中幸存的残遗物种,为我国荒漠地区唯一的超旱生常绿阔叶灌木树种,集抗旱、抗高温、抗冻、耐盐碱、耐腐蚀等多种抗逆性于一身,在林木抗逆性研究领域具有极其重要的科研价值。本文重点从抗冻性、遗传多样性、分子遗传学、提取物这些方面分析了沙冬青的研究特色,探讨了建立沙冬青抗逆模式灌木的潜力及应用。As one of the surviving plants of third generation of ancient Mediterranean coast, Ammopiptanthus mongolicus （Maxim.） is a high stress resistance shrub endemic in northwest area of China and is the only super-dry evergreen broadleaf shrub in the desert of China, which integrates with poly drought resisting, high temperature resisting, antifreeze, alkali resistance, corrosion resistance and other resistance in one that have very important scientific research value. The research characteristics of A. mongolicus in aspects of its frost resistance, genetic diversity, molecular genetics and tree body extract were analyzed, and the potentiality and application prospects of developing an A. mongolicus adverse-resistant model shrub in the future were discussed.
