title: [Life form spectra, leaf character, and hierarchical-synusia structure of vascular plants in Thuja sutchuehensis community].
abstract: 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.
