| 摘 要： | 庞泉沟自然保护区共有种子植物89科359属809种,其中裸子植物2科6属7种,被子植物87科353属802种。含5属以上的科15科,单、寡种属共330属,这些科、属在植物区系组成中具有重要作用。种子植物科、属、种的区系地理成分复杂多样。科的分布区类型中,世界分布型40科,北温带分布型24科,分别占总科数的44.94%和26.97%。属的分布区类型中,温带成分256属,占总属数的82.05%,反映出该区植物区系的温带性质。种的分布区类型中,中国特有分布种居首位,尤以华北成分占优势,其中华北落叶松、黄刺玫、油松等为该区植被建群种或优势种。科、属、种的特有现象不平衡,没有中国特有科,中国特有属、特有种分别为7属、325种。

| Abstract: | In Pangquangou Nature Reserve,it was known that there were 809 species of seed plants in the region,which belonged to 359 genera and 89 families.Among them there were about 2 families 6 genera 7 species in Gymnospermae,and 87 families 353 genera 802 species in Angiospermae.15 families were more than 5 genera and 330 genera were not more than 5 species.These families and genera played(important) roles in seed plants flora.Analysis based on families,genera and species shown that the floristic elements in the region were diversity.Families: Cosmopolitan type was dominant in the families.It had 40 families.North Temperate type(24 families) was on the second place.Genera: Temperate floristic(elements) were significant in genera flora.256 genera belonged to temperate type,which accounted for(82.05%) in total genera.Moreover,Species endemic to China were the largest type of species elements.North of China elements were especially predominant.Some species such as Larix principis-rupprecht,(Rosa) xanthina and Pinus tabulaeformis were constructive or dominant species of the region vegetation.It was different in endemic of families,genera and species.There was no family,but 7 genera and 325 species were endemic to China. |
