Abstract
应用双向指示种分类法(TWINSPAN)和典范对应分析法(CCA),对干旱区艾里克湖湿地植物群落特征指数与土壤环境因子的关系进行研究。结果表明,研究区的29种主要植物,隶属12科27属,分为4个种类组,大多数物种丰富度较低,其中胡杨、毛柽柳、芦苇和西伯利亚泡泡刺是最常见的种类。TWINSPAN分析表明,该区25个样地分为3个主要类型组,组1包括6个样地,组2包括18个样地,组3包括1个样地,分别代表不同土壤有机质、全氮、全磷含量的3种生境。CCA排序结果同TWINSPAN分类结果基本一致,反映出植物群落分布格局随土壤因子变化的趋势,确定了影响该区植物群落盖度的土壤因子为有机质、全氮、全磷
