Studies on relationships of epiphytic bryophytes and environmental factors in forest ecosystems in Changbai Mountain forests
长白山森林生态系统树附生苔藓植物分布与环境关系研究

Detrended canonical correspondence analysis (DDCA)and detrended correspondence analysis(DCA) were applied to study the relationships of the main epiphytic bryophytes and the environmental factors in 36 sites in the forest ecosystems in Changbai Mountains The results showed that host species, place on trunks, canopy density, altitude, inclination angle and the direction of the host trunks are the five important factors influencing the distribution of epiphytic bryophytes
