The distribution characteristics of Paphiopedons scabra in southeastern Yunnan and the composition of plant communities were investigated and the flora was analyzed. The results showed that the Paphiopedons were distributed in stable shady secondary shrubs and evergreen deciduous broad-leaved forest From the upper part to the top of the mountain, the elevations are higher and the slope of the distribution area is larger with a distribution of distribution. The flora of the hardy Paphiopedicus community is complex with the tropical components in the flora accounting for 57.75% of the total genera, mainly in the tropic And the tropical Asia, the temperate component accounts for 42.25% of the total genera, with the north temperate and east Asian distribution components as the main, indicating that its habitat has the characteristics of subtropical to temperate transition, there are many residual components, with the characteristics of the ancient fauna. Often with the genus Cyclobalanopsis, Ficus, genus, Aberdeen, Sophora, the genus Sumatrathus, Spiraea, arrow bamboo genus, genus Orchid, stone peach genus, mother of the genus, madder, rabbit ears Wind is a stable plant associated.
