物种/功能群去除实验及其在生态学中的应用

随着物种多样性与生态系统功能的关系成为生态学领域研究的焦点之一,物种/功能群去除实验也逐渐得到了广泛的应用。物种/功能群去除实验在生态学中的应用主要包括以下研究内容:种间关系、多样性与生态系统功能关系、关键种的作用和功能、入侵种给生态系统带来的后果评价。针对去除实验的特点,提出去除实验应用中需要注意的若干问题,包括:"去除"行为本身对生态系统的影响、时间尺度在去除实验中对于研究结果的影响以及入侵种去除的特殊性。

Removal experiment of species or function groups and its applications in ecology

With the relationships between species diversity and ecosystem function being one of focuses in the field of ecology, removal experiment of species or function groups has been applied broadly. Its applications in ecology include the studies on: (1) interspecific relationships; (2) the relationships between species diversity and ecosystem functioning; (3) the functions of key species; and (4) the assessment of the consequences of invasive species to the ecosystem. According to the features of removal experiment, some issues deserving attention were put forward, including the effects of the removal action itself on the ecosystem of temporal scales on the research results in removal experiment, and the specialty of removal of invasive species.
