基于植物功能性状的生态学研究进展:从个体水平到全球尺度

Plant Functional Traits: From Individual Plant to Global Scale

摘要:

植物功能性状是指能够反映植物碳获取、水分传递、养分循环等的重要生命活动的属性，包括植物生理、形态和物候等方面的特征。通过植物功能性状探讨物种分布格局、生长策略和存活机制及其对全球变化的响应与适应，是近年来生态学研究的热点之一。然而，不同尺度下植物功能性状与环境因子的关系存在差异，并且性状之间的关系也不尽相同。从物种、种群、群落、植被区系到全球尺度，围绕植物功能性状之间的相互关系及其对气候环境变化响应的热点问题进行了综述，梳理了近年来植物功能性状研究领域的进展，并讨论了目前植物功能性状研究的局限性和该领域未来的发展趋势。

Abstract:

Plant functional traits (PFTs) are plant attributes that can reflect plant life history processes, such as carbon acquisition, water transport and nutrient cycling, including plant features associated with plant physiology, morphology and phenology. Employing functional traits to answer questions regarding plant distribution, growth and survival, as well as to explore the mechanisms underlying plants' response to global climate change, remains a hot research topic in ecology over the past decades. However, it has been shown that trait-trait correlation and its association with environmental factors are rather variable or even reverse across ecological scales. The research progresses related to PFTs at different scales, i.e., within species, across species, across communities and across biomes globally were summarized. The limitations of current research of PFTs and proposed future research directions in this field were also discussed.
