摘要
The regeneration, tree growth, and community structure and dynamics were studied in old-growth Korean pine (Pinus koraiensis) forest.The results showed that the formation of tree form and growth character have been obviously related with the gap-phase regeneration.The ecological effects of the gap suppress the tree growth in diameter,and control that young tree stem fork in early stage.The heterogeneity of tree growth in time and space is the results of high quality in tree height and diameter.The hardwood species mixth Korean pine have different ecological effect on regeneration and tree growth of Korean pine in the early stage of gap reconstructing. Community dynamics depends on tree gaps oceurs,in which a 'cyclic sucession'between Korean pine and hard wood species may occurs.The process would take about 200 yers.
