摘要
河岸带植物群落是河岸带生态系统的一个重要组成,具有多种美学价值、生态和经济效益。近年来,全球变化、极端天气事件频发以及人类活动等外界干扰威胁着河岸带植物群落的稳定,而韧性是有助于植物群落适应干扰的一个重要特性。因此,国际上已有众多的学者开展河岸带韧性植物群落的研究。文中在梳理国际上最新研究成果的基础上,阐明相关的重要概念,从适应能力、动态转变比对和阈值界定层面归纳河岸带植物群落韧性的评估测量指标与方法,从外来入侵植物、极端天气事件以及河流流态3个方面探讨外界干扰因素对植物群落韧性的影响,并针对韧性的内涵延伸、完善测量指标和方法以及外界干扰因素方面提出研究展望。
The riparian plant community,which contains various ecological,aesthetic,economic benefits,is a critical element of the riparian ecosystem. Recently,the global climate change,extreme weather events and human activities have been threatening the riparian plant community stability,while resilience as a significant characteristic can adapt the community to disturbances. Thus,more and more researchers have been engaged to the study of the resilience of riparian plant community. The paper reviewed the latest international researches in this field, explained several important concepts, and concluded the main indicators and methods to measure and assess the resilience in terms of adaptive capacity,regimes shift,and threshold determination. Then,we analyzed the effect of external disturbances on the resilience from the 3 aspects,i. e.,exotic invasive plants,extreme weather events and the river flow regime. Finally,we prospected the future research on the resilience connotation, measurement indicators and methods improvement,and external disturbances.
