灵石山米槠林优势树种叶片δ~(13)C沿海拔梯度的变化

摘要
为探究灵石山米槠林优势树种叶片δ13C值沿海拔梯度的变化规律,以灵石山不同海拔(157~842m,分9个海拔梯度,分别记为A1~A9)米槠林优势树种不同年龄叶片为试材,采用单因素方差分析检验各海拔梯度优势树种叶片δ13C值种间以及所有优势树种叶龄间的差异,回归分析方法探究主要优势树种叶片δ13C值沿海拔梯度的变化关系。结果表明,灵石山不同海拔米槠林优势树种的叶片δ13C平均值为-30.89‰(-34.40‰~-28.81‰);除海拔A7(632~662 m)和海拔A8(762 m)优势树种叶片δ13C值种间差异不显著外,其他海拔梯度上种间叶片δ13C值均差异显著;各海拔不同叶龄叶片的δ13C值差异不显著。在海拔A1~A9上,随海拔升高灵石山米槠林优势树种叶片δ13C值逐渐升高,平均变化量为3.2‰·km-1。随海拔变化,主要优势树种叶片δ13C值变化规律不同,说明优势树种对环境因子变化的敏感性不同,其适应策略也不同。本研究结果为米槠林优势树种对环境变化响应策略的研究提供了理论依据。
To explore variation of un-enven aged foliar δ13C value of dominant species in Castanopsis carlesii forests along elevation gradients in Lingshishan National Forest Park,foliar δ13C characteristics and changes along elevation gradients were analyzed. The difference of δ13C value in species and un-enven aged leaves of dominant species was analyzed respectively with one-way ANOVA,respectively. And the changes along elevation gradients of δ13C value was analyzed with regression analysis. Significant difference of foliar δ13C value among different species were observed at each elevation gradient except from 632 to 662 and 762 meters,while no significant difference of foliar δ13C value was found among the uneven-aged leaves. With increase of elevation gradients,foliar δ13C value significantly increased,with an increment of 3. 2‰ per 1 000 meters altitude. The responses of principal dominant species foliar δ13C to elevation were different. Elevation affected the growth strategy of dominant species in C. carlessi forests in Lingshishan. Changes of foliar δ13C value along elevation gradients were different for dominant species,indicating the different sensitivity to enviorenment and adaptive strategy. This paper provides theoretical basis for study on response strategy to environment change.
