摘要:

以内蒙古大兴安岭兴安落叶松林轻度火烧迹地为研究对象,采用分层取样的方法对群落中植被进行了调查,分析比较了不同恢复年份后兴安落叶松林群落各层物种组成及多样性的差异。结果表明:不同恢复年份后群落各层α多样性指数总表现为草本层﹥灌木层﹥乔木层的趋势。群落物种总数随着恢复时间的推移呈逐渐增多的趋势。这种变化趋势主要出现在草灌层内,而在乔木层内并不明显。群落草本层物种数除1996L以外,其它3个恢复年份均小于对照样地,而群落灌木层物种数除1996L与对照样地相当,其它3个恢复年份均大于对照样地。总体来看,轻度火干扰有利于植被的更新与演替。

Abstract:

In this study,mild burned larixgmelinii forest areas were studies in different regeneration years.The natural regeneration conditions,community structure characteristics,species composition,community biodiversity were observed and researched in 2015.The results showed that the alpha diversity index of community each layer in different regeneration years showed a ranking of herb layer > shrub layer > tree layer.The total number of species went up with the passage of time to recover a trend of increase gradually.This trend mainly appears in the herb to shrub layer,but in the tree layer is not obvious.The number of species in the herbaceous layer was lower than that of the control plot except 1996L,while the number of species in the shrub layer was equal to that in the control plot.The other three restoration years were larger than the control plots.In general,mild fire interference is conducive to vegetation regeneration and succession.

Key words: Larixgmelini forest, burned area, species composition, diversity of species
