摘要：

通过实地调查对飞龙峡森林公园公路改建工程影响区域维管束植物的种类、生活型、植被类型进行了初步研究.调查结果显示:1)区域内有维管植物62科124属146种,其中,蕨类植物9种,隶属5科5属;裸子植物8种,隶属5科7属;被子植物129种,隶属52科112属.2)在调查区域内蕨类植物多数科属只含一个物种,表明仅有少量种类的蕨类植物物种能够在此环境中生存.3)被子植物在科、属、种层次上被子植物所占比例分别为83.38%、90.32%、88.36%,占绝对优势.4)蕨类植物以世界分布占绝对优势,泛热带分布和北温带分布较少,其他分布类型均缺乏;种子植物在科的区系组成中呈现出较高的热带性质,在属的区系组成中呈现出温带性质和热带性质.建议飞龙峡森林公园内公路改建工程施工期间以及工程后期应当采取相应的移栽育苗、迁地保护和植被恢复等措施,减小对森林公园植物和生态环境的破坏.

With field investigation, a preliminary study was conducted on the species, life forms, and vegetation types of vascularl plants in the area affected by the road reconstruction project of Feilongxia Forest Park. 1） This area contains 146 vascular plant species, which belong to 52 families and 119 genera, in which 9 species of pteridophyte belonging to 5 genera and 5 families, and 8 species belonging to 7 genera and 5 families of gymnosperm, 129 species belonging to 112 genera and 52 families of angiosperm. 2） Most of the ferns in the survey area contain only one species, indicating that only a few species of fern species can survive in this environment of the Feilongxia Forest Park. 3） The angiosperms are occupied at the family, genera, and species level. The proportions were respectively 83.38%, 90.32% and 88.36%, accounting for an absolute advantage. 4） The dominant species in ferns is widespread. The pan-tropical distribution and the north temperate distribution account for a relatively small percentage. The other distribution types are all scarce; the seed plants in the family composition of the family show a higher tropical nature. It shows a temperate and tropical nature in its floristic composition. Among the vascular plants in the investigation area, most of the plants are herbaceous, many are common farmland weeds. It is suggested that in the late and during the period of road reconstruction in Feilongxia Forest Park, we should take some measures, such as transplanting seedlings, ex-situconservation and vegetation restoration to mitigate the damage to the plants and the ecological environment of forest park.
