摘　　要：于2012～2013年对河北大海陀自然保护区进行了3次全面踏查,并根据植物群落类型及其分布设置样地进行植物区系组成的详细调查,在此基础上分析了大海陀保护区维管束植物的区系组成与分布类型,并将其与周边相邻4个保护区的植物区系组成进行了比较,以明确大海陀自然保护区植物区系及其特点,为该地区的植物多样性保护提供依据。结果表明:(1)大海陀自然保护区共有野生维管束植物900种,隶属于108科,429属。其中蕨类植物14科19属28种,裸子植物2科3属3种,被子植物92科407属869种。(2)保护区内区域单种属数达到249个,占总属数的58.0%,反映了该区植物区系组成的复杂性。保护区内维管束植物属可划分为15个分布区类型,且温带性质的属是构成该区植物区系的主要组成部分,保护区内种子植物温带分布类型(8～14型)共281属,占总属数的78.3%。(3)对大海陀自然保护区与周边相邻的4个保护区植物区系组成比例进行比较发现,大海陀自然保护区与纬度相似的河北小五台山自然保护区、河北雾灵山自然保护区植物区系组成比例最为相似,同时也说明大海陀自然保护区内植物区系组成比例与所处地理区域应有的植物区系组成比例一致。The floristic compositions of vascular plants in Dahaituo Nature Reserve are investigated based on the typical plant community plots and 3 times comprehensive line transect surveys in 2012～2013.We analyzed the floristic compositions of vascular plants and its distribution type,and compared 4 nature reserves around it,so as to make clear the flora and characteristics of plants in Dahaituo Nature Reserve,and to provide a basis for plants diversity conservation in this areas.The results show that：（1）In Dahaituo Nature Reserve,a total of 900 wild vascular plant species are recorded,belonging to 108 families and 429 genera,among which,28 species are of pteridophyte,belonging to 14 families and 19 genera,3 species are of gymnosperm,belonging to 2 families and 3 genera,and 869 species are of angiosperms,belonging to 92 families and 407 genera.（2）There are 249 genera each of which only one species belong to,which reflect the abundance and complex of flora compositions.The genera of vascular plants in the Nature Reserve can be divided into 15 distribution types,and the temperate zone characteristics is prominent,for there are 281 genera belonging to temperate distribution types（8-14 types）,accounting for 78.3 percent of the total.（3）According to the compare of floristic compositions among Dahaituo Nature reserve and its 4 surrounding Nature Reserves,the floristic compositions in Dahaituo Nature Reserve is similar to the Nature Reserves with similar latitude,such as Xiaowutai Mountain Nature Reserve and Wuling Mountain Nature Reserve,and it shows that the floristic compositions in Dahaituo Nature Reserve are in accordance with them in the region.
