摘要: 植物功能性状用于揭示性状演化规律与物种进化关联,阐述物种共存机制与群落构建法则,预测气候变化和人为干扰下的植被动态。始建于2002年的西北欧植物功能性状数据库主要针对该植物区系中植物持久性、更新与传播力等相关性状,在植物生态学界具有重要影响力。本文介绍了西北欧植物区系性状数据库中的植物功能性状及其筛选与测定方法,旨在为中国相关数据库的构建提供依据,推动理论生态学与功能生态学的发展。

Abstract: Plant functional traits have long been used in revealing evolution rules of plant traits and evolutionary relationships among species, exploring mechanisms of species coexistence and community assembly, as well as in predicting vegetation dynamics under climate change and human disturbance. The LEDA Traitbase, a database of lifehistory traits of the Northwest European flora, started in 2002, mainly focusing on functional traits involved in plant species persistence, regeneration and dispersability, has significant influences in plant ecology study. This paper introduced methods for the identification and measurement of functional traits in this traitbase to provide guidelines for trait selection and measurement to facilitate the establishment of similar database in China and to advance theoretical ecology and functional ecology.
