摘要: 由于在海拔梯度上各种环境因子表现出连续的梯度性变化,以海拔梯度为平台研究植物叶片性状的适应特征有助于揭示植物对气候变化的响应,进而可以为研究全球变化与陆地生态系统的关系提供研究基础。本文重点分析了植物的叶寿命、比叶面积、叶氮含量、叶绿素含量等叶片结构性状和气孔导度、叶片羧化效率、水分利用效率和叶片δ13C等叶片功能性状随海拔梯度的变化规律和特点,探讨了植物叶片性状的研究不足及未来发展方向,以便为国内相关研究的开展提供参考。

关键词: 海拔响应, 叶片功能性状, 叶片结构性状

Abstract: A variety of environment factors show continuous gradient changes under an altitude gradient, so it is very significant to reveal the responses of the plants traits under the climatic change under altitude gradient and the results can also provide an foundation to understand the relationship between the terrestrial ecosystem and the global change. This article puts emphases on the changes of leaf span, specific leaf area, leaf nitrogen content, chlorophyll, stomata conductance, carboxylation efficiency, water use efficiency and leaf δ13C along an altitude gradient. This article also explores some uncertainties on the interpretation of mechanisms of leaf traits along the altitude gradient. This review provides a good knowledge for directing the relevant studies in China.

Key words: altitudinal response, leaf functional traits, leaf structural traits
