Summary: | Study of relations between medicinal plant species and the environment is important in plant ecology and for conservation of medicinal plants. The generalised linear model and generalised additive model were used to describe the species response to environmental gradients exhibited by a community of Phellodendron amurense (an endangered medicinal plant species) in the Xiaolongmen Forest Park, Beijing, China. Data of species abundance and environmental variables were obtained from 25 plots measuring 10 m × 10 m. The results showed that both the generalised linear model and the generalised additive model were effective in describing species-environment relations. The Gaussian model was more suitable in modelling the species response to environmental gradients. Phellodendron amurense was absolutely the most dominant tree species in the community. All dominant species in it showed a harmonious relationship. The distribution and abundance of Ph. amurense were significantly correlated with the elevation, slope position, aspect, litter thickness, etc. These must be considered for conservation of the studied species and community. |
