摘要(Abstract)：

采用典型群落样地调查法,对瓦屋山常绿阔叶次生林乔木层物种多样性特征进行了研究。结果表明:(1)瓦屋山常绿阔叶次生林乔木物种共计17种,隶属10科16属;(2)瓦屋山常绿阔叶次生林乔木层的优势种为扁刺栲(Castanopsis platyacantha)和中华木荷(Schima sinensis),主要伴生树种为硬壳柯、细梗吴茱萸五加、野桐、小叶青冈等阔叶树种;(3)瓦屋山常绿阔叶次生林乔木层物种多样性(Shannon-wiener)指数在1.25~2.68之间,生态优势度在0.17~0.45之间,均匀度指数在0.26~0.47之间;(4)瓦屋山常绿阔叶次生林在演替进化中,正由双优群落朝着多优群落的格局演替变化。
By the method of typical community survey plots,studies were made of tree layer species diversity characteristics in the Wawu Mountain of the secondary evergreen broad-leaved forest. The results showed that(1) 17 species belonging to 16 genera and 10 families constituted species of the secondary evergreen broad-leaved forest tree layer in the Wawu Mountain.(2) Dominant species were Castanopsis platyacantha and Schima castanopsis,mainly associated with broad-leaved tree species of Lithocarpus hancei,Acanthopanax evodiaefolius,Mallotus japonicus,Cyclobalanopsis myrsinifolia etc.(3) Species diversity index was between 1. 25 ~ 2. 68,ecological dominance was between 0. 17 ~ 0. 45,and evenness index was between 0. 26 ~ 0. 47.(4) The secondary evergreen broad-leaved forest succession evolved from double excellent community towards diverse excellent community patterns in the Wawu Mountain.
