通过设置临时标准地对大丰山长苞铁杉群落的区系成份，群落外貌和结构特征进行了调查与研究．结果表明该群落有维管植物96种，隶属于37科和65属．生活型谱以高位芽植物占绝对优势，占80．2％．该群落结构分明，乔木层、灌木层和草本层层次清晰．乔木层以长苞铁杉、黄山松、甜槠等占优势，但其多样性指数低于灌木层．
By setting temporary standards, the fauna composition, community appearance and structure of the Dwarf Tsuga longibracteata community in Dafeng Mountain were investigated and studied. The results showed that there are 96 species of vascular plants belonging to 37 families and 65 genera in this community. Life spectrum with high bud plants accounted for the absolute advantage, accounting for 80.2%. The community structure is clear, the tree layer, shrub layer and herb layer level clear. The arbor layer is dominated by T. longibracteata, Pinus taiwanensis and S. chinensis, but its diversity index is lower than shrub layer.
