摘  要：
采用典型抽样方法,对绵竹白云山光皮桦人工林群落的植物种类组成及重要值和α多样性进行了初步研究。结果表明:(1)组成绵竹白云山各类光皮桦林的种子植物和蕨类植物共计170种,分属58科121属,其中乔木以光皮桦占绝对主导,灌木以蔷薇科、豆科为主,草本以菊科、禾本科、荨麻科、毛茛科为主,林下植被丰富。(2)重要值中乔、灌层分别以光皮桦、悬钩子属占绝对优势,草本层以水竹叶、龙牙草、节节草、车前、艾蒿等占主导。(3)丰富度指数:草本层>灌木层>乔木层;优势度指数:草本层>灌木层>乔木层;均匀度指数:灌木层>草本层>乔木层。总体上绵竹白云山光皮桦人工林群落的物种多样性偏低。

摘  要：
Using the typical sampling method,this paper studied the plant species composition and its important value and α diversity of Baiyun Mountain Betula luminifera plantation community in Mianzhu City. The results showed that:( 1)there are 170 species belonging to 58 families 121 genera of the seed plants and ferns in the Baiyun Mountain Betula luminifera plantation. Tree is mainly Betula luminifera,shrubs are based on Rosaceae and Leguminosae,herbaceous plants are mainly Compositae,Gramineae,Urticaceae,Ranunculaceae.( 2) The importance value of tree and shrub layer is Betula luminifera and Rubus respectively. The herb layer is mainly Murdannia triquetra,Agrimonia pilosa,Equisetumramosissimum,Plantago depressa,Artemisia argyi.( 3) Richness index: herb layer > shrub layer> tree layer; dominance index: herb layer > shrub layer > tree layer; evenness index: shrub layer > herb layer > tree layer. Altogether,the species diversity of Betula luminifera plantation community of Baiyun Mountain in Mianzhu City is low.
