生态学中关键种的研究综述

A review on key species study in ecology

关键种 (Keyspecies)是生态学研究 ,特别是生物保护学研究中的一个研究热点。关键种可以是为了最大程度地保护生物多样性而进行优先保护的目标。但是目前的研究来看 ,在群落或者生态系统中确定关键种不是一件容易的事情。本文通过对有关关键种研究的回顾 ,探讨了国内外的研究状况 ,着重说明了关键种在实际研究中的实践以及存在的局限性 ,并且重点阐述了确定关键种的一些实验方法和定量测度方法 ,并进行了简要的评述。

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.
