 Twentynine quadrats belonging to various habitats were sampled in Yaoluoping National Nature Reserve, lichen species in each quadrat were identified and the lichen coverage of each quadrat was measured, combined with several environmental indices, with the purpose of understanding the lichen distributing pattern and community quantitative characteristics. Factor analysis was used to appraise relationships among ecological factors, cluster analysis and Spearman rank correlation coefficient test were employed for ordination and Fisher’s exact test was applied to evaluate interspecific correlation. Factor analysis showed that the number of species decreased as the altitude increased, and there was significant positive correlation between dominant species quantity and coverage (P=0.034), very significant positive correlation between humidity and habitat type (P=0.001). Based on cluster analysis data, twentynine quadrats were divided into 5 types of association. Fisher’s exact test indicates 10 species pairs were very significant positive association and four species pairs significant positive, but no species pair was negative significant association. Fisher’s exact test demonstrated that the competition between the species was low.
