摘　　要：通过样地调查法对中泰南五味子伴生群落的植物组成进行调查,在此基础上对中泰南五味子伴生群落的种子植物区系组成及其特征进行分析,结果表明:中泰南五味子伴生群落共出现维管束植物40科61属71种,其中蕨类植物3科3属3种,种子植物37科58属68种,种子植物中具有3个种以上的优势科有9个,单种科和单种属所占比例较大;植物区系地理成分在科的组成上有5个分布区类型和3个变型,以泛热带分布为主,所占比例高达94.59%;属的组成中有7个分布区类型和5个变型,热带成分类型及其变型占绝对优势,共计56属,占种子植物总属数的96.55%,表现出较强的热带性质;中泰南五味子伴生群落区系起源古老。The seed plants floral composition and characteristics in concomitant community of Kadsura ananosma were analyzed,based on the investigation of plants in concomitant community of Kadsura ananosma by sample plot investigation method.The result showed that there were 40 families of vascular plants including 61 genera and 71 species in concomitant community of Kadsura ananosma,in which pteridophytes comprised 3families,3genera and 3species,seed plants 37 families,58genera and 68 species.There were 9dominant families with more than 3species,The single species family and single species genera had a high proportion in total species.About the floristic elements,there were 5distribution area types and 3subtypes at the family level,and mainly elements was pantropic which proportion was 94.59%;and for genus level,the floristic elements was mainly tropical elements,there were 7distribution area types and 5sub-types,in which the tropical distribution area types and sub-types including 56 genus was the biggest and the proportion was 96.55%.The floristic origin of concomitant community of Kadsura ananosma was ancient.
