Abstract:: In this paper, we studied the influence of disturbance patterns (thinning and thinning+replanting) on the species diversity of understory plants in Cupressus funebris plantations in the Yangtze River Forest Farm in Yunyang County, Three Gorges Reservoir area. Investigations were conducted by establishing 325 sample plots in the different experimental sites. Diversity of different patterns (T0, T1, T2, T3, T4, T5 and T6) was surveyed by sample plot method in summer in 2008.Based on the calculations of α-diversity such as Simpson index, Shannon index and Pielou index, we analyzed the species diversity of different models in C. funebris plantations. The results showed that anthropogenic disturbances had altered the light conditions of understory, improved the growth of vegetation, and impacted obviously the species diversity of higher vascular plants. There were 2～3 times species in all of the models plantations more than those of in the control plantations. According to control plantations, the diversity of shrub layer was different with different models, but the diversity of plant species of herbaceous layer was significantly higher in C. funebris plantations with different models than those in the control plantations.
