This paper mainly deals with those lichens species
which are key contributors for the formation of soil crust in southern fringe of Gurbantunggut Desert
Xinjiang Uyghur Autonoumous Region
China.Thirteen lichens species
namely Diploschistes muscorum(Schreb.)Norm.
Fulgensia bracteata(Hoffm.)Raws.
Xanthoria elegans(Link)Th.Fr
Caloplaca songoricum A.Abbas
Psora decipiens(Ehrh.)Hoffm.
Collema tenex var.corallinum(Massal.)Degel.
Collema tenex(Sw.)Ach.em.Degel
Candeleriella aurlla(Hoffm.)Zahlbr
Lecanora argopholis(Ach.)Ach
Dimelaena oreina
Lecidea sp.
Acarospora strigata
Catapyrenium sp.were isolated and identified from the desert soil crust.Also we found that there is closely relationship between the lichens species and solar radiation
