在对安徽宁国板桥自然保护区次生甜槠林进行群落调查的基础上，应用单木竞争模型及数量分析方法和计算机模拟技术，对甜槠种内及甜槠与其他种群之间的竞争关系进行了分析。研究结果表明，甜槠种内竞争比其与其他树种的种间竞争激烈，甜槠在种间竞争中占有较大优势，将长期保持稳定。竞争强度随着对象木的径级增加而减小，竞争木对对象木的竞争强度与对象木的径级之间的数量关系均可用反函数模型来拟合，且拟合效果很好。

Resorting to single tree competition index model, quantitative analysis and computer simulation technology, the paper analyzes the intra and inter specific competition of Castanopsis eyrel in Banqiao Natural Reserve in Anhui province on the basis of community investigation. The results show that intra specific competition is more intensive than inter specific competition of C. eyrel. C. eyrei takes up a large advantage in interspecies competition and will keep its stability in a long time. The intra specific competition intensity in C. eyrei decreases gradually with the increase of diameter class of object trees. The relationship of competition intensity be- tween competitive trees and object trees and the diameter class of object trees can be fitted to inverse function model.
