群落可入侵性及环境胁迫

Community Invasibility and Environmental Stress

摘要:

群落的可入侵性研究是入侵生态学的中心内容。从群落进化历史、群落结构、繁殖体压力、干扰和胁迫等5个影响入侵的主要因素综述了近年来群落可入侵性研究的工作进展和成果,其中重点阐述了群落结构对入侵的影响,包括群落物种组成、物种多样性和物种功能群多样性的诸多实验研究和相关假说,并用理论模型结合具体实验研究探讨了环境胁迫和可入侵性的关系。针对目前群落可入侵性研究存在的问题提出了自己的见解。

Abstract:

Community invasibility is a focus research in invasion ecology. Fact or s influencing the invasibility are reviewed including evolutionary history, comm unity structure, propagule pressure, disturbance and stress. Related hypoth esis and experimental research on the effects of community structure (species compos ition, species diversity and species functional groups) on invasibility a re pres ented. The relationship between environmental stress and invasibility ar e also e xpounded.
