Type and dynamics of age structure of Keteleeria davidiana var. chien-peii population and its relationship to community succession and environment were analyzed. The results showed that the age structures were classified into four types:growing, stable, initial and middle sensecent types. The survival curves had concave, convex, disconnected and dotted shapes. Along with development and succession of community, the age structure changes from growing, stabilized, senescent to residual type. The important factors causing change to the age structure were biological features of Keteleeria davidiana var. chien-peii, development of broad-leaved tree species, geographic isolation, and human disturbance.
分析了百山祖冷杉种群年龄结构的类型、动态及其与群落演替和环境的关系。结果表明，年龄结构分为增长型、稳定型、初始型和中度衰退型四种类型。存活曲线具有凹型、凸型、不连续型和点状型。随着群落的发育和演替，年龄结构从增长型、稳定型、衰退型转变为残留型。导致年龄结构变化的重要因素有百山祖冷杉的生物学特性、阔叶树种的发展、地理隔离和人为干扰。
