Abstract
The characteristics of natural regeneration seedlings of Pinus sylvestris var.mongolica have been investigated in the chosen sample area with seed trees at different density,single seed tree and burned area.The results show: because of the different density of seed trees,there is obvious difference at the quantity and age structure of natural regeneration seedlings.The age structure of natural regeneration seedling of Pinus sylvestris var.mongolica can′t be continuous at the time.The density of natural regeneration seedling is different with the different types of forest stand,which is related with site condition,tree age and spatial distribution.
