浙江天台山石梁常绿阔叶林研究

Study on evergreen broad-leaved forest of Shiliang in Tiantai mountain of Zhejiang province

石梁常绿阔叶林中，常见的种子植物有１３１种，隶属４４科，８５属，其中属于热带类型的有３６属，温带类型的有４６属。据１４个样地统计，该常绿阔叶林的第一优势种或建群种为甜槠，次优种或共建种为木荷。按Ｒａｕｎｋｉａｅｒ生活型统计，该群落的生活型高位芽植物种类最多，地面芽植物次之，地下芽植物较少。该群落叶的性质以小型叶、单叶、草质、非全缘为主。而在乔木层中却以中型叶、单叶、革质、非全缘为多。群落的层次分明，垂直结构可分为乔木层、灌木层、草本层和地被层。

The floristic composition and community characters of evergreen broad-leaved forest atShiliang in Tiantai Mountain, Zhejiang province had been studied. The result shows that there are131 seed plants, belonging to 85 genera of 44 families, of which 36 genera are of tropical form, 46genera of temperate zone form. According to a survey of 14 sample plots, the first dominant speciesor edificato of the evergreen broad-leaved forest is Catanopsis evrey, and the second dominant species or coedificato is Schima superba. By the method of Raunkiaer's life-form statistics,phaenerophytes are the first in species number of the community life form, hemicrptophytes the second and geocrytophytes the third. The characters of leaf are mainly microphyll. simple, herbaceousand unentire,And the characters of the leaf in tree layer are mostly mesophyll, simple, coriaceousand unentire There is a clear distinction between layers, and the vertical structure can be divided into tree layer, shrub layer, herbaceous layer and ground layer.
