摘要: 在次生林改造过程中,对林内形成的大小不等的林隙运用班块状造林技术,取得好的效果。运用该项技术不仅使林隙内的目的树种-红松生长发育迅速,并促进了周围次生林木的生长,而且也使草本植物在种类、密度和盖度等方面有了明显的变化。本文就这一问题进行研究,认为光是影响草本植物生长和分布的一个关键因子,林隙对促进草本植物发育,提高物种多样性具有重要意义。

Abstract: In the course of restoration of the secondary broad-leaved forest, the gaps which existing in the forest with different areas had been reformed by the gap technique and had yielded good results.It not only made the aim species growing up well in the gaps and promoted the growth of broad-leaved trees which surrounding the gaps, but also changed herbs in many respects such as species, density and cover degree.
In this paper, we reseach on herbs which in gaps and under the broad-leaved trees.The results showed that light is a key factor to the herb's growth and distribution.It is of great immediate significance that the gaps will promote the herb's growth and enhance the species diversity.
