摘要
对新疆天山大峡谷地衣进行调查研究,查阅相关资料,初步对该地区地衣进行分类和整理。结果表明: 该区地衣有81种,隶属5目,15科,26属,其中地卷属,石蕊属和蜈蚣衣属种类最多,分别占14. 81% ,12. 35% 和 9. 87% 。我们将新疆天山大峡谷地理区系划分为世界广布区、环北极广布区、欧亚-北美分布区、环北极-高山分布区、环北方分布区、欧亚-北非分布区、地中海-西亚和中亚分布区、北温带分布区和中国特有等 9 种类型。研究还发现该地区岩树枝及树皮生地衣与朽木生地衣占主导地位。
The lichens flora of Tianshan Daxiagu, Xinjiang were preliminarily studied according to field investigation and literature. We used the Color test （ CT）, Microcrystal test （MCT） and Thin layer chromatography （ TLC ） method to classificated the lichens species. Eighty-one lichen species in 26 genera and 15 families from Tianshan Daxiagu were reported here. There are three major genera have more than 8 species, about 14.81% , 12.35% and 9.87% species respectively. The result shows that lichens flora in this region includs following nine types： Wide-spread species, Widespread continental regions of North Hemisphere species, Euro-Asian north American species, Circumpolar arctic-alpine species, Circumpolar boreal species, Euro-Asian north African species, Mediterranean-West Asian and Central Asian, Temperate zone species and Endemic to China. The local lichens were divided into 8 different ecological types according to the lichens substrate and environmental condition.
