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
