森林生态系统中关键种与群落动态的关系研究进展

Research Progress of the Relationship Between Keystone Species and the Dynamic of Community in Forestry Ecosystem

森林生态系统中的群落在不同演替阶段的关键种有所不同,而不同类型的关键种存在于不同的生态系统以及群落当中。文中阐述了关键种通过种间交互作用、物种多样性以及群落结构和演替3种途径对群落动态的影响,探讨了关键种的确定方法以及关键种影响群落动态的研究手段,针对关键种研究中存在的问题展望了未来研究的热点以及可能的研究方向。

Keystone species are different in different succession stages of community of forestry ecosystem, and different types of keystone species also exist in different ecosystems or communities. This paper mainly elaborated the relationship between keystone species and the dynamic of community, and the way of keystone species influencing the community, namely interaction strength between species, the diversity of species, and the structure and succession of community. Futhermore, this paper explored the methods to identify the keystone species and the means to research how keystone species impact communities. Based on the problems existing in the research on keystone species, the hotspot issues and possible research directions Were prospected for the future research.
