尧山自然保护区野生木本植物调查与分析

摘要

为掌握尧山自然保护区内种质资源现状,对尧山自然保护区野生木本植物进行了实地调查,共调查植物65科,165属,535种,11变种.其中,蔷薇科Rosaceae、豆科Leguminosae等6个科是含有20种以上的大科,另有较大科12个,中型科32个,单种科15个;优势科有忍冬科Caprifoliaceae、槭树科Aceraceae等12个,共343种;较大属10个,中型属26个,寡种属61个,单种属68个;165个属分成13个分布类型,7个变型,其中较多的为北温带分布(24.85%)、东亚和北美洲间断分布(12.73%)以及泛热带分布(12.12%),尧山野生木本植物区系以温带成分为主,又有亚热带和热带成分,过渡特征明显.保护区内植物生活型丰富,以落叶树种为主.%In order to grasp the present situation of germplasm resources in Yaoshan Nature Reserve,field investigation was conducted on wild woody plants in Yaoshan Nature Reserve.A total of 65 families,165 genera,535 species and 11 varietas of plants were investigated.We found Rosaceae,Leguminosae and other 6 families were more than 20 species of large families,the other 12 larger families,32 middle-sized families and 15 families with only one species. Twelve families such as Caprifoliaceae and Aceraceae were dominant families and a total of 343 species.There were 10 bigger genus,26 middle genus,61 little genus and 68 genus with only one species. 165 genera could be classified into 13 distribution types and 7 subtypes of north temperate(24.85%)mainly,East Asian and North America disjuncted (12.73%)and pantropic(12.12%)distribution type. The flora of wild woody plants in Yaoshan had the higher percentage of temp distribution elements and the subtropical and tropical elements which showed the obvious character transition.The life type of the plants in the reserve was rich which were mainly deciduous tree species.
