摘要: 植物叶片功能性状反映了植物对环境的响应以及对资源的获取和利用策略。本研究以武夷山自然保护区青冈为对象,分析了青冈不同叶片功能性状在海拔上的差异。结果显示:(1)随着海拔的升高,叶片的氮含量(N)、磷含量(P)、叶面积(LA)、比叶面积(SLA)、叶质量(LM)均呈先上升后下降的变化趋势,在海拔1600 m处显著高于1400 m与1800 m;(2)海拔1400 m处的青冈叶片功能性状变异程度明显高于1600 m与1800 m,此外,除海拔1400 m叶面积与叶生物量变异系数高于25%外,各海拔其他功能性状指标(C、N、P含量、C/N、C/P、N/P、比叶面积)变异系数均在9%以下;(3)海拔1400 m与1800 m青冈采取的是资源保守策略,而海拔1600 m则采取资源获取策略。本研究结果表明,不同海拔青冈的叶片功能性状存在差异,且采取的资源获取与利用策略不同。

Abstract: The functional traits of plant leaves reflect the responses of plants to environment and the strategy of resource acquisition and utilization. In this study, we analyzed the changes of leaf functional traits of Cyclobalanopsis glauca with altitude in Wuyishan Nature Reserve. The results showed that: (1) With increasing altitude, nitrogen (N) content, phosphorus (P) content, leaf area (LA), specific leaf area (SLA), and leaf mass (LM) all initially increased and then decreased. All the leaf functional traits at altitude of 1600 m were significantly higher than those at altitude of 1400 m and 1800 m; (2) The variation degree of leaf functional traits of C. glauca at 1400 m was significantly higher than those at 1600 m and 1800 m. In addition, the variation coefficients of LA and LM were higher than 25% at 1400 m, while those of other functional traits (C, N, P, C/N ratio, C/P ratio, N/P ratio, SLA) at each altitude were below 9%; (3) Leaf functional traits of C. glauca showed a conservation strategy at the altitude of 1400 m and 1800 m, while those showed a acquisition strategy at the 1600 m altitude. Therefore, there are altitudinal variations of leaf functional traits of C. glauca, resource acquisition and utilization strategies.

Key words: altitude, leaf, functional trait, resource acquisition strategy, Cyclobalanopsis glauca.
