摘　　要：1 969年 ,由Paine提出的“关键种”概念 ,迅速成为国际生态学的研究热点。关键种理论从系统调控的水平 ,揭示了生态系统稳定性和物种多样性的一种维持机制 ,并对保护生物学具有指导意义。但是关键种的确定标准、普适性及研究方法等方面仍存在局限性。关键种理论还需要通过大量观察和实验加以补充、论证与完善。The concept of “keystone species”,put forward by Robert T Paine in 1969,has rapidly become a popular field of international researches on ecology.On the level of systematical control,keystone species theory reveals a sort of mechanism of sustaining stability and species diversity in ecosystems,and has guiding significance for conservation biology.However there are still some limits in the identification criteria,generality,and methodology of keystone species.Much more observation and experiments are required to enrich,testify and improve the keystone species theory.
