摘要:
为研究不同干扰模式（间伐，间伐+补植）对三峡库区云阳县长江防护林带植物多样性的影响，根据云阳县柏木人工林区高等维管植物调查数据，采用Simpson指数、Shannon指数和Pielou均匀度指数等进行α多样性测度分析。结果表明：不同间伐和补植等干扰模式均改变了柏木林生境，对柏木林林下高等维管植物多样性产生了较大影响，植物种类和数量均发生了变化，植物种类平均高出对照2～3倍；与对照相比，随着干扰模式的变化，灌木层多样性指数发生了不规则变化，草木层多样性指数呈明显增加趋势。
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.
