摘　　要：采用样方法调查了崖柏群落的植物组成,分析了维管束植物的生活型组成、叶子性状及层次层片结构.结果表明:崖柏群落的植物生活型组成以高位芽植物为优势,占73.2%,地面芽植物占18%,地下芽植物占6%,地上芽和一年生植物各占2%和0.8%.叶质以纸质和革质为主,分别占48.8%和36.4%;叶级以小叶为主,占60.8%;叶缘以非全缘叶为主,占56.8%;叶型以单叶为主,占86%.崖柏群落可分为乔木层、灌木层和草本层,层间植物较少,各层次分别由常绿针叶、阔叶及落叶阔叶高位芽植物层片、常绿和落叶矮高位芽植物层片、地面芽和地下芽以及一年生植物层片构成.Based on the investigation of the plants in Thuja sutchuenensis community, the life form spectra, leaf character, and hierarchical-synusia structure in the community were analyzed. The life form spectra of the plants in the community were 73.2% of phanemphyte, 18% Of hemicryptophyte, 6% of geophyte, 2% of chamaephyte, and 0. 8% of annual plants. The leaf quality was mainly of papery and conaceous, which occupied 48.8% and 36.4%, respectively. The dominant leaf size was microphy （60. 8% ）, dominant leaf margin was un-entire （56.8%）, and dominant leaf form was simple （86%）. The T. sutchuenensis community had three sub-layers, i.e. tree layer, shrub layer, and herb layer, with lesser interlayer plants. Each layer was respectively composed by phanemphyte evergreen coniferophyte, broadleaf and deciduous broad-leaf plants, nanophanerophyte evergreen and deciduous broad-leaf plants, as well as hemicryptophyte, geophyte, and annual plants.
