摘　　要：植物会产生诸多适应性特征以适应环境、维持生长,而这些性状特征的变异可以在多个尺度发生。传统生态学大多聚焦于物种间尺度上的变异,但越来越多的研究表明物种内的变异程度不容忽视,忽略种内变异会导致在量化植物群落构建、生态策略及物种生态位空间等方面缺乏置信度。本文在归纳以往相关研究的基础上,发现植物功能性状的种内变异主要来源于遗传变异、表型可塑性、植物功能性状的局域快速适应以及个体发育差异等几个方面。而植物功能性状种内变异的量化方法主要包括变异系数、性状梯度分析法、方差分解法、T统计量法及植物功能多样性法。本文以植物功能性状种内变异为主题,系统综述了植物功能性状及其变异在来源、量化方法上的发展,评估了不同方法的优缺点,探讨了其在植物群落构建机制方面的研究进展,并提出其在未来发展的应用。Plants develop adaptive traits that vary at multiple scales.Traditional ecology focused mainly on interspecific variations.However,recent researches demonstrate that the degree of intraspecific variations cannot be ignored.Ignoring the intraspecific variations can result in low confidence in quantifying community assembly,ecological strategies,and niche space.By reviewing literature on intraspecific variations of plant functional traits,we identified that these variations primarily arise from genetic diversity,phenotypic plasticity,local rapid adaptation,and ontogenetic differences.The commonly used statistical approaches in the context include traitgradient analysis,coefficient of variation,variance decomposition,T statistics,and plant functional diversity.This study provides a comprehensive overview of research development of intraspecific variations in plant functional traits and the prevailing statistical methods.Additionally,we evaluated the aforementioned methods and discussed their applications and future advancements in the research of community assembly and other areas of community ecology.
