初步整理了分布在天山一号冰川的地衣种类,共5目12科24属51种。地衣区系上包括世界广布种、环极北极高山种、环极低北极及北方种、环北方种、两极和大西洋种、温带种、东亚种、东亚—北美西部、北欧—巴基斯坦—北美种、中亚分布种、北半球大陆广布种、两半球广布种、中国特有种等。同时结合地衣的生长环境特征将该地区的地衣分藓丛生、土生、草地生、地面生、石浮土生、岩面生、荒漠风滚、树皮或树枝生、朽木生地衣种等9种生态类型。

A total of 51 lichen species belong to 5 orders, 12 families and 24 genera were recorded according to the investigation data and research materials of flora and ecological distribution types of lichens species at the No. 1 glacier in Tianshan Mountains. The lichen floras include 13 types, namely cosmopolitan species, circumpolar arctic alpine species, circumpolar low arctic and boreal species, circumpolar boreal species, bipolar and Atlantic species, temperate zone species, east Asia species, east Asia-North America species, Scandinavia-Pakistan-North American species, Middle Asia species, widespread species in the northern hemisphere, widespread species in both hemispherical species, and endemic species in China. Moreover, lichens were divided into nine ecological types according to the lichen distribution and substratum types.
