Epiphyte is an important structural component of the forest ecosystems and is of great significance for maintaining forest ecosystem species diversity and ecosystem functions. In this paper, the diversity of epiphytic vascular plants and their relationship with the microhabitats are analyzed by investigating the epiphytic vascular plants in monsoon evergreen broad-leaved forests in different microhabitats. The results showed that a total of 12,302 epiphytic vascular plants of 97 species were recorded in the monsoon evergreen broad-leaved forest, belonging to 16 families and 45 genera. The species-abundance curve shows that Belvisia henryi, Vittaria linearifolia, and Humata platylepis have obvious advantages. Epiphytic vascular plants in mountain ridge habitats have higher species diversity and individual abundance, while those in gentle slope and valley habitats have lower individual abundance of epiphytic vascular plants. There are significant differences in the abundance of epiphytic vascular plants between different diameter classes and different heights (P<0.05). The species are mainly distributed in the middle and small diameter hosts and the middle and lower parts of the tree trunks. The main environmental variables that affect the species richness and individual abundance of epiphytic vascular plants are altitude, light intensity, and temperature. The relationship between epiphytic vascular plant species richness and altitude and light intensity can be determined by the regression equation y=0.05x1 -0.007x2-59.842 (R2=0.391, P=0.000) means that the relationship between abundance, altitude and light intensity can be described by the regression equation y=0.793x1-0.057x2-1056.27 (R2=0.204, P=0.000).
