摘　　要：依据新版《国家重点保护野生植物名录》,通过查阅对比文献和馆藏标本,梳理分析甘肃省国家重点保护野生植物多样性。结果表明,甘肃省国家重点保护野生植物有6大类52科83属125种2亚种8变种。一级保护植物4种2变种,二级保护121种2亚种6变种。其中,物种数量最多的科属分别为兰科28种、杓兰属16种。中国特有属8个,特有物种66种及种下阶元。地理分布统计的结果表明,甘肃省国家重点保护野生植物绝大多数分布在陇南市、甘南州和天水市的森林植被带中,与甘肃省植物多样性的分布规律基本一致。According to the New List of National Key Protected Wild Plants,diversity of national key protected wild plants in the Gansu province have been analyzed by consulting and comparing literature,and Herbaria specimens’ information.Data analysis shows that the Gansu province is diverse with 125 species,2 subspecies,8 varieties,83 genera,52 families and 6 categories of key protected wild plants.First-level key protected wild plants consist of 4 species,2 varieties,second-level key protected wild plants consist of 121 species,2 subspecies,6 varieties.The top family is Orchidaceae (28 species),followed by Cypripedium (16 species).There are 8 genera,66 species (including subspecies and varieties) endemic to China.The results of geographical distribution statistics indicate that most of the national key wild protected plants in Gansu province are distributed in the forest vegetation belt of Longnan city,Gannan Tibetan Autonomous Prefecture and Tianshui city,and the distribution pattern are consistent with the distribution pattern of plant diversity in Gansu province.
