  • 摘要: 为了探究连续海拔梯度上亚高山-高山草甸群落多样性、碳氮磷化学计量特征及其环境适应策略,以五台山南坡自然分布的亚高山-高山草甸群落为研究对象,沿海拔梯度(2 201~3 011 m)设置9个样地,采用相关性分析、偏冗余分析(pRDA)的方法,分析亚高山-高山草甸群落多样性和碳氮磷化学计量特征及其与环境因子的关系. 结果表明:在五台山南坡2 201~3 011 m海拔范围内,亚高山-高山草甸群落的Patrick指数、Shannon-Wiener指数、Simpson指数、Pielou指数平均值分别为11、2.15、0.87、0.93. 随着海拔的升高,Patrick指数、Shannon-Wiener指数、Simpson指数均呈显著下降趋势,而Pielou指数变化不显著. 群落TC、TN、TP含量平均值分别为461.19、23.32、1.96 mg/g,C∶N、C∶P和N∶P平均值分别为19.99、242.17、12.10. 与全球尺度和草地生态系统区域尺度的研究相比,该区域草甸群落具有相对稳定的TC含量,以及TN、TP含量高和N∶P低的特点,群落水平下相对较低的N∶P(<14)说明草甸群落植物生长更倾向于受氮元素的限制. 随着海拔升高,群落TC含量、C∶N、C∶P沿海拔梯度均呈显著上升趋势,而群落TN、TP含量均呈显著下降趋势,群落N∶P变化不显著. 在海拔梯度上,群落碳氮磷化学计量特征存在差异性,在一定程度上说明了草甸群落对海拔生境的不同适应策略. 偏冗余分析结果表明,环境因子(海拔和土壤因子)分别解释了亚高山-高山草甸群落多样性和碳氮磷化学计量特征总变化的70.8%和67.8%,海拔因子的解释贡献率大于土壤因子. 研究显示,海拔和土壤因子对五台山亚高山-高山草甸群落多样性和碳氮磷化学计量变化特征存在显著影响,其中海拔因子的影响尤为突出.
