Abstract: In order to find out epiphytic lichens species composition and discuss the relationship between environmental factors and epiphytic lichens community distribution pattern,we use the Detrended Correspondence Analysis(DCA) for grouping the sampling points according to the lichens coverage;Canonical Correspondence Analysis(CCA) is used to analyze environmental correlation of species distribution of epiphytic lichens.The result showed that there were 49 epiphytic lichens belonging to15 families,30 genus .Based on the numerical analysis result the 20 sampling points could be identified as three groups.Group 1 includes 22 lichen species and total coverage of 2.639%,species diversity index is 1.603;Group 2 has 27 species and total coverage of 3.717%,the species diversity index is 1.972;Group 3 has 12 species and the smallest total coverage of 1.036%.The result of CCA analysis showed that altitude,air humidity,forest canopy coverage,light intensity are the four major environmental factors influencing the distribution patterns of the epiphytic lichens in the study area.

Key words: epiphytic lichens, numerical analysis, species distribution pattern, Altay two river source nature reserve
