【摘要】 为给丰宁云雾山森林公园植物资源保护、合理利用提供理论和科学依据,以河北省丰宁县云雾山森林公园种子植物为研究对象,运用实地调查、标本采集、形态学鉴定和室内统计等方法,对该地区植物区系特征进行研究。结果表明:森林公园有野生种子植物92科338属671种(含种下分类单位,下同),其中裸子植物3科5属7种,被子植物89科333属664种;对种子植物属划分的15个分布类型进行统计得出:北温带分布成分有132属,占该区总属数(世界分布除外)的44.6%,反映出该植物区系具有明显的北温带性质;此外,该区分布着很多古老的类群和白垩纪及第三纪的孑遗植物,且单种属和寡种属共205属,占该区总属数的60.7%,说明植物起源比较古老;该区中国特有分布共7属,说明特有现象存在,但不明显。更多还原

【Abstract】 In order to provide theoretical and scientific basis for the protection and rational use of plant resources in Yunwu Mountain Forest Park,the seed plants in Yunwu Mountain Forest Park in Fengning county of Hebei province were studied.The characteristics of flora in this area were investigated through field survey,specimen collection,morphological identification and indoor analysis.The results showed that there were 92 families,338 genera,and 671 species(including subspecies taxa,the same below)of wild seed plants in the forest park.Among them,three families,five genera,seven species belong to gymnosperms,and89 families,333 genera,664 species belong to angiosperm.The analysis of the 15 distribution types of the seed plant genus showed that 132 genera are the North Temperate type,accounting for 44.6%of the total number of genera(Cosmopolitan Type not included).It was reflected that the flora of this area was obvious north temperate dominated.In addition,there were many ancient taxa,such as the Cretaceous and Tertiary relict plants,distributed in the region.And there were 205 genera of monotypic or minor genera,accounting for60.7% of the total number of genera in the region,indicating that the flora origin was relatively old.There were seven Chinese endemic genera in this area,indicating that unique phenomena exist but were not obvious.更多还原
