九峰国家森林公园维管束植物区系研究

Study on the Flora of Vascular Plants in Jiufeng National Forest Park

摘要:

通过对九峰国家森林公园的调查分析得知：①九峰国家森林公园共有维管束植物 139 科，356 属，484 种，其中木本植物 215 种，草本植物 269 种，草本植物略占优势；②野生植物有 95 科，238 属，314 种；人工栽培植物 77 科，134 属，170 种，以野生植物占优势；③在科的组成上以小型科为主，物种数最多的科为禾本科，有 31 属 38 种；属的组成上以单种属和寡种属为优势，是本地区植物成分的重要组成类群；④植物区系成分复杂，在科级水平上，表现出了明显的热带性质，在属级水平上则表现出热带?温带成分并重的趋势，说明本植物区系具有明显的热带向温带过渡性质。

Abstract:

Plant species were investigated in the Jiufeng National forest park.This result showed that:①A total of 484 species of vascular plant belonging to356 genera,and139 families are maintained in the Jiufeng National forest park,including215species of woody plants and269 species of herbaceous plants,the herbs were dominant.②Wild plants were dominant,there were 314 species in238 genera of 95 families of wild plants found in the area,and the cultivated plants there were 170 species in 134genera of 77 familie.③Gramineae was the most species,including38species belonging to31 genera,Based on the family the small families were the main components.The genera with only one or a few species were abundant in the flora for genera level, which was constitute an important group of plant in the area.④The flora was complicated in composition,the result clearly showed a tropical nature for family level and showed the trend of paying equal attention to both tropical and temperate components for genus level.So that this flora has obvious tropical to temperate transitional nature.
