植物叶片功能性状及其环境适应研究

Research on leaf functional traits and their environmental adaptation

植物叶片是连接植物与外界环境的重要桥梁,其功能性状变化受外界环境和系统发育的共同影响。充分了解不同环境下叶片功能性状的变化对探讨植物对环境的适应性具有重要意义。本文阐述了叶片功能性状的类型及其功能意义,综述了影响叶片功能性状2个主要因素(环境因子和系统发育历史)的相关研究,探讨了叶片功能性状对植物适应环境的意义。最后,对叶片功能性状研究的现状及未来趋势进行了展望。

Plant leaves represent an important interface between a plant and the surrounding environment,and their functional traits are influenced by the external environment and phylogeny. Elucidating variations in leaf functional traits in different environments is crucial to understand plant adaptation. In this paper, the types and functional significance of the functional traits of leaves are summarized. Related studies on the two main factors affecting the functional traits of leaves（ environmental factors and phylogenetic history）, as well as involvement in plant adaptation,are also discussed. Finally,we propose prospective research directions based on the current situation and future tendency of leaf functional trait studies.
