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
