摘要:

以内蒙古大兴安岭兴安落叶松林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,分析比较了不同火烧木管理方式下兴安落叶松林林下群落恢复过程中物种组成、多样性指数及地上生物量的差异。结果表明:火烧木择伐方式下火烧迹地与未火烧对照样地林下群落相似性最大。不同火烧木管理方式下,火烧迹地林下群落多个α多样性指数均表现为草本层>灌木层的趋势。不同火烧木管理样地草本层Simpson和Shannon-Wiener指数均小于对照样地,而在灌木层都大于对照样地。3种不同类型火烧木管理方式火烧迹地恢复13年后,林下草本层生物量均小于对照样地,而灌木层生物量较对照样地相比都有不同程度的增加。

Abstract:

In this study,Larix gmelinii forest burned areas were observed under different firewood management modes.The natural regeneration conditions,species composition,aboveground biomass,community biodiversity were researched in 2016.The results showed that the similarity of understory community under the burntwood selective cutting mode compared with unburned area showed the highest.The alpha diversity index of community at each layer under different burntwood management modes showed a ranking of herb layer > shrub layer.The simpson and shannon-wiener indexes in herb shrub layers were increased compared with unburned area,while the two indices are larger than the unburned area in the shrub layer.After thirteen years,the understory herb layer biomass was less than that of the control plot,while the shrub layer biomass increased to varying degrees compared to the control plot.

Key words: Larix gmelini forest, burned area, burntwood management, diversity of species, aboveground biomass
