摘　　要：为了解黑龙江小北湖国家级自然保护区种子植物分布,并为其保护提供科学依据,对保护区的种子植物区系进行野外调查和分析。结果表明:小北湖国家级自然保护区有野生种子植物87科296属559种,其中裸子植物1科4属6种,被子植物86科292属553种;小北湖国家级自然保护区种子植物具有多种地理分布,属、种的热带性质、亚寒带-寒带性质占比少,温带成分占绝对优势,温带分布属222个,占总属数的89.16%,其中北温带分布占温带分布属的61.26%;温带分布种440个,占总种数的81.78%,其中中国-日本分布和东北分布占温带分布总种数的48.41%,且具有多种森林的建群种及优势种,在区系构成中作用突出。In order to understand the distribution of seed plants in Xiaobeihu National Nature Reserve in Heilongjiang and provide scientific basis for its protection,field investigation and analysis of the seed plant flora in the reserve were carried out.Results:There are 559 wild spermatophyte species belonging to 87 families,296 genera including 6 gymnosperm(1 family,4 genera)and 553 angiosperm(86 families,292 genera)in Xiaobeihu National Nature Reserve.This area consists many geographical elements.The proportion of genera and species belonging to tropical and subfrigid zone-cold zone elements was little.The temperate element was absolutely dominant.There were 222 genera(89.16%of all the genera)belonging to temperate genera of which 61.26%were north temperate genera.There were 440 species(81.78%of all the species)belonging to temperate species of which species spread in China-Japan and the northeast of China occupied 48.41%.Meanwhile,many dominant species and constructive species of forest belonged to temperate species which play important role in the floristic composition.
