摘要
天台山的七子花林，常见的种子植物有１２５种，隶属５１科，１０２属。其中热带类型３６属，温带类型５２属。按Ｒａｕｎｋｉａｅｒ生活型统计，高位芽植物占７０．８％，地面芽植物占２２．３％，地下芽植物占４．６％，一年生植物占２．３％，高位芽植物的比例与本省常绿落叶阔叶混交林的生活型谱近似。叶级以小型叶为主，占５３．１％。叶型以单叶比例最大，占７８．５％。群落结构可分为乔木层、灌木层、草本层和地被层。
There are totally 125 species belonging to 102 genera of 51 families in the Heptacodium miconioides forests in the Tiantai Mountains of Zhejiang Province.In this paper, the Heptacodium miconioides community are analyzed on the basis of the floristic composition,the dominant species,and the physiognomy and structure of the community.According to Raunkiaer,the life form statistics are as follows:phaenerophytes(70.8%),hemicryptophytes(22.3%),geophytes(4.6%)and therophytes(2.3%).The life form spectrum of the evergreen and deciduous broad-leaf mixed forest of Zhejiang Province is the high percentage of phaenerophyta.The leaf size class of the vegetation is mainly microphylla(53.1%),and 75.8 percent of the leaf pattern is simple leaf.The community can be structurally divided into arboreous layer,shrub layer,herbaceous layer and ground layer.
