Diversity and Fungal Features of Lichen Species in Xinjiang of China
保护生物多样性是当今世界环境保护的热点问题,也是环境可持续发展以及生态文明建设的重要内容,是全球面临的紧迫任务.以实地调查为基础,同时参考前人研究资料,全面分析了新疆地衣物种资源多样性及其特征.结果显示:已报道的分布在新疆地区的18目41科160属的594种地衣中,包含10个种以上的优势科有梅衣科Parmeliaceae、黄枝衣科Teloschistaceae、蜈蚣衣科Physciaceae等15科,共计208种,占总种数的35.02％.含有5个种以上的优势属有石蕊属Cladonia P.Browne、微孢衣属Acarospora A.Massal.、地卷属Peltigera Willd.、平茶渍属Aspicilia A.Massal.等30属,共包含385种,占总种数的64.81％.单种科有13科,占总科数的31.70％;单种属有81属,占总属数的50.63％.地衣区系中大型地衣共有301种,隶属于71属,19科,占总种数的50.67％.微型地衣共有293种,隶属于32科89属,占该地区总种数的49.33％.新疆地区已发现的蓝藻型地衣共有62种,隶属于3目8科21属,分别占科、属、种总数的19.51％、13.1％、10.44％.新疆独特的地理位置孕育了特殊和丰富的地衣多样性,具有重要的研究与保护利用价值.
Protection of biodiversity is a hot and urgent issue for today's environmental conservation.It is also a content of great importance for our environmentally sustainable development and global ecological civilization as well.Through conducting the field investigation together with referring to the information obtained from the publicly reported researches,characterization of lichen species in Xinjiang was carried out comprehensively.A total number of 594 lichen species have been reported to distribute in Xinjiang area,which belonged to 18 orders,41 families and 160 genera.There were 15 dominant families containing more than 10 lichen species such as Parmeliaceae,Teloschistaceae and Physciaceae,accounting for 35.02％(208 species)of the total number of species.There existed 30 dominant genera,on the other side,including more than five species such as Cladonia P.Browne,Acarospora A.Massal.,Peltigera Willd.and Aspicilia A.Massal.,accounting for 64.81％(385 species)of the total number of species.There were 13 families with only a single species,accounting for 31.70％of the total number of families.There were 81 genera with only one species,accounting for 50.63％of the total number of genera.Classification of the growth forms demonstrated an existence of 301 macrolichens which belonged to 71 genera and 19 families,accounting for 50.67％of the total number of species.The remaining(293 species)was confirmed as the microlichens which belonged to 89 genera and 32 families,accounting for 49.33％of the total number of species in this area.Results obtained from the classification of photobionts,moreover,indicated the existence of 62 cyanobacterial lichens in Xinjiang which belonged to three orders,8 families and 21 genera,accounting for 19.51％,13.13％and 10.44％of the total number of family,genus and species,respectively.It thus can be concluded that the unique geographical location of Xinjiang should have created a specific and rich diversity in lichens,which has a great value of research,protection and utilization as well.
