Abstract:
We examined the response of woody plants to internal forest disturbance during subalpine succession and its underlying driving mechanism by comparing changes of woody plant diversity of Abies-Tsuga forests in arrow bamboo (Bashania faberi) after flowering and die-back. We calculated species diversity indices (a-diversity and β-diversity) for survey data from six fixed plots at the “Wuyi Peng” area in Wolong Nature Reserve, Sichuan Province in 1984 and 2013 to understand changes in species flora and species diversity over time (including the prophase and post-phase of bamboo regeneration and restoration). The results showed that the species composition and diversity index of trees in Abies-Tsuga forests did not change significantly before and after regeneration and restoration of arrow bamboo but maintained at a relatively stable state (P > 0.05). In contrast, species diversity, and importance values of shrubs changed significantly between the prophase and post-phase regenerative and restorative periods, and the species composition and diversity index of Abies-Tsuga forests increased slightly ( P < 0.05). Variation was seen in tree diversity patterns, as changes in the tree species in the sample plots below 3000 m above sea level was small, but there was a significant change seen in the sample plots above 3000 m above sea level. In contrast, the diversity of shrubs was significantly different in all plots, showing a slight increasing trend. At the same time, there were no significant differences in tree species diversity of Abies-Tsuga forests between different sites before and after regeneration and restoration of arrow bamboo. Shrubs were significantly correlated with each other in the early stage; only several plots and several indexes were significantly altered in the later stage, and the rest had no significant statistical effects. In a word, this result reflects the stability of species composition in climax communities, the variability of species diversity of Abies-Tsuga forests during the process of bamboo regeneration and restoration, and the adaptation of diverse types of plants (tree species, shrubs) to environmental changes,and this provides a basis for developing strategies of the biodiversity conservation and the ecological restoration of wild giant panda habitats.
