摘要： 采用植物群落学方法对崂山三桠乌药群落组成和结构进行分析。结果表明崂山三桠乌药群落共有木本植物31科54属88种，个体数最多的前10个树种占总个体数的52.45%；群落中物种Raunkiaer频率等级分布为A＞B＞C＞D=E，说明三桠乌药群落树种分布较均匀。重要值位于前7位的树种有三桠乌药、赤松、小米空木、日本落叶松、盐肤木、日本花柏、胡枝子其重要值分别为8.82%、8.53%、8.19%、6.31%、5.96%、5.44%、5.37%。群落的垂直结构层次明显，可分为乔木层、灌木层、草本层以及层间植物。群落建群种为赤松，日本落叶松为第二建群种。乔木层优势种为盐肤木、日本花柏、刺楸、辽东桤木。灌木层优势种为三桠乌药、小米空木、胡枝子、垂丝卫矛。层间植物以菝葜、华东菝葜为主。

Abstract: The community composition and structure of Lindera obtusiloba in Laoshan is analysised using means of phytocoenology. The result showed that 88 species, belonging to 54 genera, 31 families were identified in this community,the individuals of top 10 species made up 52.45% in total;The distribution of Raunkiaer frequency was A>B>C>D=E, indicated that the species are well-distributed. Lindera obtusiloba, Pinus densiflora, Stephanandra incise, Larix gmelinii, Rhus chinensis, Chamaecyparis pisifera and Lespedeza bicolor were top 7 species with importance value 8.82%, 8.53%, 7.13%, 6.31%, 5.96%, 5.44% and 5.37%. The vertical structure could be divided into arbor layer, shrub layer, herb layer and interstratum plants. The constructive and second constructive species were Pinus densiflora and Larix kaempferi. Rhus chinensis, Chamaecyparis pisifera, Kalopanax septemlobu and Alnus sibirica were primary species in arbor layer while the shrub layer was dominated by Lindera obtusiloba, Stephanandra incise, Lespedeza bicolor and Euonymus oxyphyllus and the dominate species in interstratum plants were Smilax china and Smilax sieboldii .
