摘要:
运用混合线性模型、主成分分析和零模型方法,以乌拉特荒漠草原草本群落为研究对象,研究了短期养分添加(NPKμ,各10 g·m-2)和干扰对植物群落物种多样性、功能性状、土壤理化性质和群落构建过程的影响。结果表明:(1) 干扰和交互处理显著降低物种丰富度和β多样性,短期养分添加显著降低土壤pH,增加土壤电导率。(2) 干扰和养分添加处理下,优势物种沙生针茅(Stipa glareosa)、骆驼蓬(Peganum harmala)、猪毛菜(Salsola collina)和蒙古虫实(Corispermum mongolicum)的6个性状以及群落功能性状加权均值(Community-weighted mean, CWM)发生显著变化,揭示了干扰和养分添加促使群落优势种从保守型策略向获取型策略转变。(3) 两种零模型结果表明,对照下的草本群落构建趋向于随机性过程,干扰和交互处理下的群落构建趋向于确定性过程,养分添加处理下的群落构建趋向于较弱的确定性过程。荒漠草原草本植物群落通过优势物种和关键功能性状的改变来响应和适应养分添加与干扰。
