| 摘 要： | 植物功能性状反映了植物对生长环境的响应和适应,是连接植物与环境的桥梁,研究植物功能性状特征及其随坡向梯度的变化规律,对认识不同微气候生境下植物群落空间格局形成及适应机制具有重要意义。以桂林岩溶石山灌丛植物为研究对象,分析了灌木群落水平上植物叶功能性状与环境因子关系随阴坡-阳坡梯度的变化规律。结果表明:比叶面积为阴坡大于阳坡,叶干物质含量和叶片厚度为阳坡大于阴坡;土壤含水量、有机质含量、总有机碳含量和有效氮含量为阴坡大于阳坡,土壤温度和土壤全氮含量为阳坡大于阴坡;多元逐步回归分析表明,影响群落水平植物叶功能性状的主要环境因子随阴坡-阳坡梯度而发生显著的变化。在阴坡上,对比叶面积影响显著的是土壤有效氮含量,对叶干物质含量影响显著的是土壤温度和土壤总有机碳含量。而在阳坡上,对比叶面积影响显著的环境因子是土壤含水量和土壤pH值,对叶干物质含量影响显著的环境因子是土壤全氮含量,对叶片厚度影响显著的环境因子是土壤温度、土壤全氮含量和土壤全磷含量。同一叶功能性状在阴坡-阳坡梯度上受到不同环境因子的控制,同时各叶功能性状又能够对阴坡-阳坡所处特殊生境产生一定的适应性。
