摘要
从群落学角度研究了卧龙自然保护区的四川红杉林群落．资料表明，该群落中共有种子植物３４科６３属９６种；属种分布以温带分布区类型占绝对优势；以单叶、非全缘、草质和小型叶为主的落叶高位芽植物决定群落的外貌特征，但间杂有少量的针叶常绿大高位芽植物；群落具过渡性；其群落结构明显分为乔木层、灌木层和草本层，并有层外植物４种．
In this paper,the features of the Larix mastersiana communities in Wolong Nature Reserve are studied on the basis of the floristic geographical composition,the dominant species and the physiognomy and the structure of the community. The data show that there are 34 families,63 genera and 96 species in the community,and the genera and species which belong to the type of the temperate distribution region are dominant,and the physiognomy of the community is characterized by highleveled deciduous plants with single leaf,unentire leaf,microphyll and herbaceous leaf,but there are a few evergreen highlevel coniferous trees. The community possesses the nature of evident transition. Its community structure divides into tree stratum,shrub layer and herb layer,and it includes 4 species of interstratum plants.
