摘　　要：通过对珍稀渐危植物新疆野巴旦杏的野外调查,结合其分布格局,并参考国内专家学者对野巴旦杏生物学特性、遗传多样性、生殖生物学、生理学、病理学等的研究成果,对新疆野巴旦杏濒危原因进行了探讨。结果表明:新疆野巴旦杏渐危的原因是种子不易传播、病虫害发生的频率高且危害性大、结实率低且遭鼠害啃食严重、火灾发生的概率高。Considering the distribution pattern, the thesis investigates the rare endangered species-Xinjiang Amygdalus ledebouriana in the wild, referring to domestic experts＇ study, including biological characteristics, genetic diversity reproductive biology, physiology, pathology of Arnygdalus ledebouriana and so on, and its reasons of becoming endangered were discussed. The results showed that the preliminary reasons including the seeds were difficult to spread, the frequency of plant diseases and insect pests were high and the harm was huge, the maturing rate was low and the damage caused by rats was serious, the probability of fire occurrence was high.
