摘　　要：在群落样方调查的基础上,对浙江大盘山和华顶山的华顶杜鹃群落的种类组成、群落垂直结构和生活型组成进行了分析.结果表明:华顶杜鹃群落中植物组成丰富,共有64科、102属、138种,对科属的区系分析表明群落处亚热带北缘,海拔较高;群落分层现象较明显,乔木层、灌木层和草本层物种种类丰富,层间植物种类也较丰富;生活型组成中,高位芽植物占优势,地上芽植物、地面芽植物和一年生植物很少,地下芽植物也占较高比例,叶型以单叶种类占优势,叶级以小型叶和中型叶占优势,反映出群落所处的生境温热多湿,但因处于较高海拔而明显受到温度的影响.Based on community investigation, the paper analyzed the species components, community vertical structure and life forms of Rhododendron huadingense in Dapan Mountain and Huading Mountain in Zhejing province. The results show the species richness in the community of R. huadingense, and there are 138 species, which belong to 102 genera of 64 families. The floristic analysis of families and genera shows that the communities locate in the northern edge of subtropics with high altitudes. The communities are composed by obvious layers, with rich species of trees, shrubs, herbs and interlayer plants. For the components of the life forms, the phanerophytes is dominant, with low percentage of the chamaephytes, hemicryptophytes and therophytes, and the geophytes occupied high percentage. For the aspect of the leaf types, species with simplex leaves are dominant, and microphyll and mesophyll types show the dominance of the leaf forms. The communities of R. huadingense is in the climate of warm and moist conditions, and also is affected by the temperature because of considerable high altitudes.
