雷公山自然保护区雷公山玉山竹群落植物区系分析

Flora Analysis of Yushania leigongshanensis Community in Leigongshan Nature Reserve

开展雷公山玉山竹群落植物区系分析,旨在研究该竹种的植物区系性质,为其保护和利用提供科学依据。本文采用样线法和样方法相结合的研究方法调查了雷公山自然保护区内雷公山玉山竹群落维管束植物,发现共有维管束植物53科90属132种,以单种属和寡种属为主,植物成分较为复杂。53科可划分为8个分布区类型和3个变型、90属可划分为11个分布区类型和3个变型,科、属植物区系除去世界分布类型,均表现出热带分布和温带分布占比较高的特点,表明雷公山玉山竹群落植物区系具有热带与温带的双重性质,以热带为主。

A flora analysis was conducted on the Yushania leigongshanensis community of Leigongshan Nature Reserve.The flora properties of this bamboo species were determined for its protection and utilization.Sampling and Line transects were combined to investigate the vascular plants.It was found that there were 132 species of vascular plants in 53 families,and 90 genera,particularly for the single species and oligospecies with the complex plant components.53 families were divided into 8 types of distribution zone and 3 forms,while 90 genera were divided into 11 types of distribution zone and 3 forms.Except for the world distribution types,the flora of families and genera shared a relatively high proportion of tropical and temperate distribution,indicating the dual nature of dominating tropical and temperate.The finding can also provide the scientific basis in the flora of the Yushania leigongshanensis community in Leigongshan Nature Reserve.
