摘要
为完成自身生命历程,物种在形态、生理、生态特征等方面表现出相应的功能性状。性状的特征值及其变异和分布是生物多样性的功能组分,即功能多样性,有助于维持生态系统的功能服务与健康运转。对生态系统功能多样性的研究拓宽了人们对生物多样性及其时空变化的理解,为如何将形态结构与生态功能结合的难题找到了一个突破口。本文从物种功能多样性衡量指标的提出、计算和应用入手,全面回顾了功能多样性研究的发展过程,并以案例形式从不同目的、不同角度阐述了它们在鱼类研究中的应用。针对目前的研究现状提出了鱼类功能多样性研究面临的挑战,即急需建立一套有效的性状指标,并关注功能多样性变化的内外机制和环境变化下的性状再分布等。
To complete the life cycle,species exhibit corresponding functional traits in morphology,physiology,ecology,etc.The eigenvalues,variation,and distribution of functional traits are the functional components of biodi-versity,namely functional diversity,could maintain the service function and healthy operation of ecosystems.The application of functional diversity broadens our understanding of biodiversity and its temporal and spatial variations,and provides a breakthrough to the problem of how to combine morphological structure with ecological function.I re-viewed the research process of functional diversity from the perspective of proposing,calculating,and applying the parameters of functional diversity,as well as the application of functional diversity from different purposes and per-spectives.I put forward the challenges and countermeasures of related studies.In the future,researches should pay attention to establish a set of effective trait indicators,discover the internal and external mechanisms driving func-tional diversity variations,and map the redistribution of traits under environmental changes.
