| 摘 要： | 朝鲜崖柏为国家二级重点保护植物,是长白山区特有的濒危树种,具有重要的经济价值和观赏价值.在对朝鲜崖柏主要分布区野生资源进行调查基础上,首次利用个体基径和年龄数据建立不同群落朝鲜崖柏种群的龄级结构、静态生命表和生存函数,用动态指数和时间序列分析预测其种群发展趋势.结果表明: 朝鲜崖柏种群的龄级结构呈“∩”型,属衰退型;分布于暗针叶林下的朝鲜崖柏种群存活曲线趋向于Deevey-Ⅲ型,纯林群落种群趋向于Deevey-Ⅱ型;种群生存分析显示,暗针叶林下朝鲜崖柏种群的生存函数呈现不规则的波动状态,种群分布表现为早期锐减、中期稳定、后期衰退的动态特征,纯林群落中,种群分布表现为早期稳定、中期增长、后期缓慢衰退的特点;动态指数和时间序列分析显示,暗针叶林下朝鲜崖柏种群的衰退速度略高于纯林群落.综合分析表明,朝鲜崖柏种群具有一定的恢复能力,应适当采取人工抚育,促进其种群正常更新.

| Abstract: | Thuja koraiensis, a second-class nationally protected plant species, is a unique endangered tree species in Changbai Mountain, with important economic and ornamental value. In this study, the age structure, static life table, and survival function of T. koraiensis were established by using individual root diameter and age data based on investigation of wild resources in the main distribution areas of T. koraiensis. The population development trend was predicted by dynamic index and time series analysis. The results showed that the age-class structure of T. koraiensis population was in the shape of “∩”, which was a decline type. The survival curve of T. koraiensis population under the dark coniferous forest was the Deevey-Ⅲ type, and was Deevey-Ⅱ type in pure forest community. Population survival analysis showed that the survival function of T. koraiensis appeared irregular fluctuation under the dark coniferous forest. The population distribution showed dynamic features of sharp drop in early age period, stable in middle age period, and decline in old age pe-riod. In the pure forest community, the dynamic pattern was characterized by the stability in early age period, growth in middle age period, and recession in old age period. Dynamic index and time series analysis showed that the decline rate of dark coniferous forest community was slightly higher than that of pure forest community. Our results showed that T. koraiensis had some recovery ability and that artificial tending should be used to promote its normal regeneration. |
