| 摘 要： | 分析了内蒙古草地植物的6个功能性状在种间、种内不同种群间和同一种群内不同个体间的变异.结果表明,除株高外其余5个功能性状的变异主要来自种间,但种内变异占总体变异的比例不能被忽视.不同功能性状的种内和种间变异的程度和来源不同,说明不同物种、不同性状对环境变化的响应不同.因此利用功能性状进行各种研究时,应该充分考虑种内变异的影响.

| Abstract: | Plant community structural and ecosystem functional correlations with plant functional traits is a hot spot in modern ecological research.Most assumed that intraspecific trait variation was small enough to be neglected and only focused on interspecific variation.However few works studied variation of intraspecific functional traits and relative importance of intra-and interspecific variation.This article analyzed variation in plant functional traits in Inner Mongolia grassland at different levels,interspeci... |
