摘　　要：对重庆涪陵区磨盘沟桫椤群落进行调查研究.其结果如下:该群落种类组成丰富,种群生活型谱以高位芽植物占优势,植物的区系组成反映了明显的亚热带植被的地理分布特点,群落垂直结构分层明显,水平结构差异较大.因此,应建立桫椤自然保护区,开展就地保护和科学研究.Alsophila spinulosa community was investigated at Mopan Ditch in Fuling District, Chongqing City. The results showed that the species composition was abundance,and the dominant life type is phaenerophyte. The floral composition is of obvious subtropic characteristics of the vegetational distribution. The vertical layering is obvious, and the horzonal difference is great. So, its necessary to establish the nature reserve of Alsophila spinulosa, and develop the local protection and scientific study.
