摘要:
为了阐明冷箭竹(Bashania faberi)开花枯死后的自然更新恢复过程中,冷杉-铁杉林内木本植物多样性的变化特征,洞悉亚高山森林植被在群落内部扰动影响下木本植物的响应,以四川卧龙自然保护区“五一棚”区域内的森林固定样地为研究对象,采用常规群落学调查方法,分析了冷杉-铁杉林内冷箭竹更新恢复前期与后期的木本植物多样性特征。结果表明,木本植物中乔木树种的种类组成、多样性指数在冷箭竹更新恢复前后期之间没有显著变化(P > 0.05);灌木植物的种类和同种植物的重要值、以及多样性指数在前后期之间都有明显的变化,种类和多样性指数都略有增加(P < 0.05)。且不同样地在更新恢复前后期之间,木本植物的多样性表现出不同的变化规律,海拔3000 m以下的样地乔木树种的变化较小,海拔3000 m以上样地有显著性变化;而灌木植物多样性在所有样地中都具有明显的差异,呈略微增长趋势;同时,不同样地之间在冷箭竹更新恢复前后期的乔木树种多样性,两两之间相差不明显,灌木植物在前期彼此相关较大,后期仅个别样地、个别指数有显著性差异,其余都无明显的统计学意义。本文研究结果体现出演替顶级群落物种组成的稳定性,物种多样性在竹子更新恢复过程中的波动性,以及不同生活型植物(乔木树种、灌木植物)对环境变化适应的差异性,这为制定生物多样性保护与野生大熊猫栖息地生态恢复的策略提供了依据。(图3 表4 参54)
Abstract:
We examined the response of woody plants to internal forest disturbance during subalpine succession and its underlying driving mechanism by comparing changes of woody plant diversity of Abies-Tsuga forests in arrow bamboo (Bashania faberi) after flowering and die-back. We calculated species diversity indices (a-diversity and β-diversity) for survey data from six fixed plots at the “Wuyi Peng” area in Wolong Nature Reserve, Sichuan Province in 1984 and 2013 to understand changes in species flora and species diversity over time (including the prophase and post-phase of bamboo regeneration and restoration). The results showed that the species composition and diversity index of trees in Abies-Tsuga forests did not change significantly before and after regeneration and restoration of arrow bamboo but maintained at a relatively stable state (P > 0.05). In contrast, species diversity, and importance values of shrubs changed significantly between the prophase and post-phase regenerative and restorative periods, and the species composition and diversity index of Abies-Tsuga forests increased slightly ( P < 0.05). Variation was seen in tree diversity patterns, as changes in the tree species in the sample plots below 3000 m above sea level was small, but there was a significant change seen in the sample plots above 3000 m above sea level. In contrast, the diversity of shrubs was significantly different in all plots, showing a slight increasing trend. At the same time, there were no significant differences in tree species diversity of Abies-Tsuga forests between different sites before and after regeneration and restoration of arrow bamboo. Shrubs were significantly correlated with each other in the early stage; only several plots and several indexes were significantly altered in the later stage, and the rest had no significant statistical effects. In a word, this result reflects the stability of species composition in climax communities, the variability of species diversity of Abies-Tsuga forests during the process of bamboo regeneration and restoration, and the adaptation of diverse types of plants (tree species, shrubs) to environmental changes,and this provides a basis for developing strategies of the biodiversity conservation and the ecological restoration of wild giant panda habitats.
