The intensity of disturbance is an important factor influencing functional diversity of mountain meadow communities. The change pattern of functional diversity of mountain meadow communities along a tourism disturbance gradient in the Donglingshan Reserve was studied. Sixty plots of 2 m × 2 m of meadow communities were established, and species composition, traits and environmental variables were measured and recorded in each plot. Five functional diversity indices based on functional distances, such as FAD, MFAD, FDp, FDc and Rao indices, were used to calculate functional diversity. The results showed that functional diversity in meadow communities varied greatly. Functional diversity showed a linear decrease pattern with increase of disturbance intensity. Functional diversity was significantly correlated with disturbance intensity, elevation and slope. Functional diversity was quadratically increased with species richness and also correlated with species diversity and evenness. Environmental filtering was important to functional diversity pattern. The five indices were all effective in the analysis of functional diversity of mountain meadow communities. And functional diversity can be used as indicator of disturbance and degradation of mountain meadows.
