摘要
油松栎林群落是具有沈阳地域特色的地带性植物群落,城市园林在构建植物配置时,要遵循地带性植物群落结构的规律。因此,研究油松栎林群落的结构对城市园林建设有一定的指导意义。采用典型样地调查法对油松栎林群落的结构进行研究,得出对其产生影响的相关指标。沈阳天柱山油松栎林群落有种子植物122种,分属38科74属,通过对重要值大小的分析比较,得出乔木层的主要优势种为油松、蒙古栎、辽东栎和花曲柳,灌木层的主要优势种为胡枝子、榛子、花木兰和接骨木;对油松栎林群落生活型进行分析,可知地面芽植物所占比例最多(38.12%),其余依次为高位芽植物(27.64%)、隐芽植物(22.87%)、1年生植物(8.1%)和地上芽植物(3.27%);油松栎林群落分为乔木、灌木和草本3个基本层,其中灌木层的优势较差;油松栎林群落水平结构的特点是同类植物成片状均匀分布,各物种间混交性差,其中乔木层的平均郁闭度为0.75,灌木层的平均盖度为0.27,草本层的平均盖度为0.46。
Pinus tabulaeformis and Quercus mongolica mixed forests were regional characteristic zonal plant community in Shenyang,people should follow the species composition and structure law of zonal plant community when the plants were built in urban landscape.Therefore,the research on species composition and community structure of Pinus tabulaeformis and Quercus mongolica mixed forests was the guiding significance to urban landscape construction in Shenyang.Applying the releve method to species composition and community structure could reach the conclusions of relevant indicators.In tianzhushan of shenyang,Pinus tabulaeformis and Quercus mongolica mixed forests had 122 species of seed plants,belonging to 38 families and 72 subjections.Through analysis and comparison of significant value,the main dominant species in arbor layer were Pinus tabulaeformis 、 Quercus mongolica 、 Quercus liaotungensis Koidz and Fraxinus rhynchophylla Hance.The dominant species in shrub layer were Lespedeza bicolor Turcz,Corylus heterophylla Fisch,Indigofera kirilowii Maxim.ex Palib.and Sambucus williamsii Hance.The micryptophytes were accounted for 38.12%,phanerophytes for 27.64%,cryptophytes for 22.87%,therophytes for 8.1% and chamaephytes for 3.27% by analysing the life forms.Vertical structure of Pinus tabulaeformis and Quercus mongolica mixed forests were divided into arbor,shrub and herb,the shrub layer had less advantage than the arbor and herb.The characteristics of the horizontal structure was that the similar plants were a uniform sheet,while the various plants were mixed among the species in a poor condition.The
