摘要
目的:全面掌握黑茶山国家级自然保护区地衣资源现状,为该保护区的生物多样性保护及研究提供科学依据。方法:通过实地调查、标本采集,在实验室进行物种鉴定,从多样性、生境类型、区系成分和物种相似性等方面进行研究。结果:保护区内共有地衣15科23属36种,其中1科2属5种为山西省新记录。生境主要有树生、石生、藓丛生、草地生、土生地衣和多生境等类型,其中以石生为主。保护区内地衣区系成分主要有世界广布成分、泛热带成分、东亚及北美间断、泛北极成分。该保护区与驼梁山保护区物种相似性最高。结论:黑茶山国家级自然保护区地衣以茶渍科(Lecanoraceae)为优势科,石蕊属(Cladonia Wigg.)为优势属;泛热带成分为主,与泛北极成分有一定联系。
Objective:To comprehensively grasp the current status of lichen resources in the Heicha Mountain National Nature Reserve,and provide basis for protecting lichen species diversity.Methods:Based on field investigation and specimen collection,the specimens were studied in terms of diversity,habitat,floristic composition and species similarity.Results:A total of 15 families,23 genera and 36 species were identified in this area.Among them,1 family,2 genera and 5 species were reported for the first time in Shanxi Province.In the forest area there were 6 types of lichen communities which were distributed on the trees,rocks,mosses,grassland,soil and multi-habitats respectively.The lichen community distributed on rocks was the dominant type.The floristic composition of lichen was diverse,with four floristic elements identified,including cosmopolitan element,pantropical element,East asian-North America element and cricumpolar element.It had the highest species similarity with Tuoliang Mountain Reserve.Conclusions:Among the lichens in the nature reserve,Lecanoraceae was the dominant family,and Cladonia.was the dominant genus.Pantropical elements were predominant and that were associated with circumarctic elements.
