摘　　要：[目的]通过实地调查历山国家级自然保护区地衣资源,探究其种类组成和多样性特征,为补充该地区地衣研究的基础资料提供依据。[方法]从物种多样性、生境、区系成分等多方面对保护区内地衣进行研究。[结果]该地区共有地衣15科22属39种,其中2属5种为山西省新记录。区内地衣生境共分4种:树皮或树枝生地衣群落、藓丛生群落、草地生群落、石生群落,其中树皮或树枝生群落占比最高。区内地衣区系成分多样共分4种:世界广布成分、环北极成分(9.1%)、环北方成分(68.2%)和东亚成分(22.7%)。[结论]历山国家级自然保护区地衣区系与我国北方地区植物区系成分特征相似,生境以树生为主。该研究补充了历山国家级自然保护区地衣研究的基础资料。[Objective]In this study,lichen resources in Lishan National Nature Reserve were studied through field investigation to explore its species composition and diversity characteristics,and to provide a basis for supplementing the basic data of lichen research in this area.[Methods]The lichen in Lishan National Nature Reserve was investigated for species diversity,habitat and floristic elements.[Results]The study found 39 lichen species belonging to 15 families and 22 genera in this area.To the best of our knowledge,two genera and five species were reported for the first time in Shanxi.Four habitat types were categorized as Mossy-land,bark and branches,grassland,and rocks,and bark and branches lichens were accounted for the highest proportion.The lichen flora in the region was divided into four types:Cosmopolitan element,circumpolar element(9.1%),circumpolar boreal element(68.2%),and East Asian element(22.7%).[Conclusion]The lichen flora of Lishan National Nature Reserve is similar to the flora of circumpolar boreal,and the habitat is mainly distributed in the bark and wood areas.The current research supplements the basic data of lichen in Lishan National Nature Reserve.
