This study examined the relationship between environmental factors and composition and richness of the understory species in three typical low-function forests( Pinus tabuliformis,Robinia pseudoacacia and Platycladus orientalis) in Beijing low mountain areas,to explore the response of species to the environmental factors in shrub and herb layers and confirm the primary factors determining the species richness. A total of 34 plots were established for investigation. Canonical correspondence analysis( CCA) wa...

北京市教育委员会共建项目(2009GJKY01)资助。理解驱动植物分布变异的环境因子是生态学研究的一个重要内容,其研究对象涉及森林、草甸、湿地等多类生态系统。在全球或区域尺度上,气候是决定物种组成最重要的因素(Hong et al.,2015);在局地尺度上,植被格局取决于非地带性的环境?
