文摘内容 Simultaneous flowering caused a gregarious dieback of umbrella bamboo (Fargesia murielae) all over the world in 1993-2000. Mountain Shennongjia in Central China's Hubei Province is the only native home of umbrella bamboo, where it dominates the understorey of the farges fir (Abiesfargesii) forest between 2 400 and 3 100 m, covering the ground for more than one century before a periodically flowering death. Data from 20 quadrats along a vegetation sequence revealed that the density, coverage,and height of umbrella bamboo negatively affected the species richness, diversity, and evenness of vascular plants in the forest. Local climax community of fir-bamboo was the poorest in species diversity, while the bamboo-free communities (i.e. shrubs and meadows)were bearing a higher species diversity. The simultaneous dieback of umbrella bamboo is an ecological relcase, which can pcriodically promote the plant diversity in the fir forest。
