摘　　要：为进一步查明托木尔峰国家级自然保护区微型地衣物种多样性,有效保护地衣资源提供依据,通过实地样地调查和查阅文献相结合的方法,整理了分布在该保护区的微型地衣共计69种,隶属于10目17科40属,其中茶渍目、黄枝衣目和鸡皮衣目占优势,共有10科23属39种,分别占该保护区微型地衣区系科、属和种总数的58.82%、57.50%和56.52%。优势科共有7个,优势科所含的属和种分别占该保护区微型地衣属和种总数的67.50%和68.12%。微型地衣区系地理成分被划分为9个地理成分和11个分布型。9个地理成分分别为世界广布成分、环北极成分、泛热带成分、温带成分、中亚成分、中亚—西亚成分、北欧—喜马拉雅—北美成分、东欧—北亚成分和中国特有成分。托木尔峰国家级自然保护区微型地衣多样性不高,南坡的种类数量多于北坡。微型地衣的区系成分以温带成分为主,其次是中国特有成分和环北极成分。This study aims to further identify the diversity of microlichen species in the Tuomuer Peak National Nature Reserve,the microlichen species diversity was analyzed on the basis of existing literature and field investigations.As the results show that,there are 69 microlichen species,belonging to 40 genera of 17 families.Among them Leconorales,Teloschistales and Pertusariales are dominated and have 39 species belonging 10 families and 23 genera,occupy 58.82%,57.50%and 56.52%of the total families,genus and species number of microlichens of this area.There are seven dominant families that have 47 species,occupy 67.50%of genera and 68.12%of total number of microlichen species respectively.The microlichen flora of this nature reserve is divided into following 9 geographical distribution types and 11 distribution types.And 9 geographical distribution types were Cosmopolitan element,Circumpolar element,Pantropical element,Temperate element,Middle Asian element,Middle Asian and west Asia element,Scandinovia-Hymalaya-North American species,East Europe-North Asian species and Endemic to China.The flora of the microlichen species is mainly composed of temperate elements,followed by Chinese endemic elements and Circumpolar element.
