摘要: 通过对带状间伐后当年和第2年巴山木竹林更新竹笋和成竹的数量、平均基径、高度的差异性分析和统计比较,表明带状间伐复壮更新方法可以改变巴山木竹竹林内部结构,竹林的发笋数和成竹数首先表现出复壮更新的优势,随着时间的推移,这种优势会逐渐减少,而对更新后竹林基径、高度促进作用在间伐第2年表现出来。可见,带状间伐在一定程度上可以使竹林老龄化和竹林质量恶化趋势有所缓解,达到复壮更新目的。

Abstract: Based on the difference analysis and statistical comparison with number,basal diameter and height of Bashania bamboo shoots and bamboo stems between the 1st and 2nd year(s) after strip thinning in Bashania Fargesi forest, it is shown that strip thinning can change the internal structure of B. Fargesi forest and increase the number of bamboo shoots and stems,and make bamboo regeneration occurr first. The effects of strip thinning will decrease with time. The effects on the basal diameter and height of both bamboo shoots and stems occurr in the second year after strip thinning. It is obvious,to some extend,that strip thinning can ease bamboo aging and quality deterioration,and finally attain rejuvenation.

Key words: Bashan bamboo forest, strip thinning, regeneration, Foping Nature Reserve
