| 摘 要： | 种群是构成群落的基本单位,种群结构不仅对群落结构有直接影响,而且能表征群落的发展和演变趋势1].种群结构包括径级结构、高度结构、年龄结构等2].年龄结构是种群的重要特征,但由于年龄的数据在许多情况下非常难于得到,因此许多学者在进行种群结构的研究过程中,都采用了大小结构分析法3-5].无论是基于年龄结构还是大小结构的种群结构分析,都经常被用来重建森林发展的历史,提供有关潜在种群长期稳定性的信息,并且预测其演替趋势6-10].森林植物种群结构在一定程度上是由自然干扰历史决定的. |

| Abstract: | In this study, Picea schrenkiana var. tianshanica forests in five different longitudinal sites (Zhaosu, Gongliu, Wusu, Urumqi and Hami) in Tianshan Mountains were investigated by using vertical transects. The percentage of trees in different sizes, the diameter classes distribution, and the fitted equations for accumulated stem percentage of P. schrenkiana var.tianshanica were analyzed in order to study the population diameter classes structure. The results showed that the decreasing order for percentage of seedling,sapling and the small trees is Hami, Urumqi, Gongliu, Zhaosu and Wusu.The distribution of stem abundance along the diameter classes in Zhaosu, Gongliu, Wusu, Urumqi and Hami all had an inversed "J" shape. The best fitted equation in Zhaosu and Urumqi for accumulated stem percentage of P. schrenkiana var.tianshanica was exponential,while the best one for another three sites was logarithmic.Gongliu preserves the best natural populations of P. schrenkiana var. tianshanica in terms of various size class analysis indexes. |
