Analysis of Natural Regeneration Characteristics in Burned Areas of Broadleaf Korean Pine Forest
This study explores the natural regeneration characteristics of broadleaf mixed forests in burned areas from four aspects:stand density,species composition,diameter class structure,and growth patterns of major tree species,providing a theoretical basis for vegetation restoration and natural forest protection in burned areas.The results show that 80 years after a fire,the main species in naturally regenerated stands are elm(Ulmus pumila)and birch(Betula platyphylla),with a hectare stock volume that is not low but has low economic value and lacks coniferous species.To accelerate the succession process of the forest stand,measures such as artificial stimulation of natural regeneration or the introduction of native Korean pine are needed to restore the burned areas to climax communities.
