Endangered Abies yuanbaoshanensis will probably have been extinct,so it very necessary to studying its genetic diversity with a proper way in order to save this key group of biological diversity in China.In the present study,AFLP(amplified fragment length polymorphism) markers was used to examine population of Abies yuanbaoshanensis in order to understand the level of population genetic variation and genetic structure.

首先，物种的遗传多样性是长期进化的结果，是其生存和发展的前提，对遗传多样性进行研究可以为分析濒危物种或种群的进化潜力和未来命运提供重要资料；其次，遗传多样性是保护生物学研究的核心之一，不了解种内遗传变异大小、时空分布及其与环境条件的关系，就无法采用科学有效的措施来挽救濒于灭绝的物种、保护受到威胁的物种，对珍惜濒危物种制定合理的保护方针和策略，有赖于对物种遗传多样性的认识。
