摘要
根据黄山松种群的静态生命表、存活曲线、大小结构图对黄山松种群数量特征的研究结果表明，黄山松种群的死亡高峰期主要出现在１级苗木向２级苗木的过渡期。黄山松种群在立地条件较好的低海拔地带从属于常绿阔叶林，其演替结果将被常绿阔叶树种所取代；而在立地条件较差，海拔较高的山顶、山脊、陡坡等地段能自然更新，形成较稳定的地形顶级群落。
Five plots are selected from different elevations and community types.Quantitative characteristics of Pinus hwangshanensis population is discussed according to the static life table, survivorship curve and size-structure are figured out as the result of plot investigation.When population of Pinus hwangshanensis occurs at a little lower elevation even fine environment, it is always substituted by hardwoods, but at the higher elevation, especially at the summits, ridges or steep slops, though the environment is poor, the population can regenerate themselves, maintaining a stable or even increasing population.The peak period of mortality occurs during the seedling grows from grade Ⅰ to grade Ⅱ.
