运用植物地理学方法，结合科学考察等野外实地调查及相关文献资料，对大黑山国家级自然保护区植物区系组成和地理成分进行统计分析。结果表明：保护区野生维管束植物中占绝对优势的是被子植物，其次是蕨类植物，裸子植物所占比例最小。在属、种水平上，较大科和大型科的区域优势明显，且科内属、种的分化强度较高，其次是6～20种的中型科具有较大种群而且具有一定的优势性，再次为寡种科，单种科对区域植物区系的影响程度最弱。植物区系的地理成分主要以北温带植物区系成分为主，植物区系中热带性质成分占一定比例。本区有中国特有分布属6属，也映了该地区独特的植物资源保护价值。

This paper studies the composition and geographic elements of flora in Daheishan National Na-ture Reserve of Liaoning Province,northeastern China by applying the methods of phytogeography,and based on field plant investigation and the relevant literatures.The results showed that among the wild vas-cular plant species,the the angiosperms is dominant,followed by ferns and gymnosperms which accounts for the smallest proportion.At the level of genus and species,the regional advantage is more obvious than the families and large families and genera,higher strength for differentiation is presented,followed by 6 to 20,the medium has a larger population and has certain advantages,again for the oligotypic families,single species effects on regional flora degree is weakest.The floristic composition is mainly in plant area of north temperate component and has some proportion of the flora of tropical nature.The region has 6 genera en-demic to China,and reflectes the protection valure of the uniqure plant resources in the area.
