A Preliminary Study on Community Characteristics of Corticolous Lichen in Forest Ecosystem in Eastern Altay Mts .

In this paper, the authors used cluster analysis method to study the corticolous lichen community structure in forest ecosystem of eastern AltayMts of Xinjiang according to the on the spot investigation results in many year. The results show that in this Mts the lichen species which can be divided into four communities: (1 ) Calicium abietinum Pers + Tephromela atra (Hundson) community; (2) Leptogium saturninum (Dicks. ) + Lecidea elabens Fr. community; (3) Parmelia sulcata Tayl. apud Mack + Ramalina farnacea (L. ) Ach community; (4) Caloplaca flavorubescens + Phaeophyscia nigricans (Flk. ) community. We also were compared the species diversity, similarity and evenness index of differentcommunities.
