Abstract: Study on key species is the focus of the ecological research,especially in the study of conservation biology.Key species can be the precedent target of the biodiversity conservation.But the identification of key species in a community or an ecosystem is much difficult.In this paper,the previous studies about the key species were reviewed,emphasizing upon the application and the limitation of the key species during the research works.Some experimental methods and quantitative measurements on the determination of the key species were given and evaluated.
