| 摘 要： | 以“空间代替时间”的方法，以种群径级结构代替年龄结构，采用静态生命表和生存分析的方法，探讨了天柱山国家森林公园黄山松种群结构和动态规律。结果表明，随海拔升高，黄山松种群密度增大，径级分布范围减小，种群存活曲线由Deevey-Ⅱ型之间过渡到Deevey—Ⅰ型，种群由稳定型过渡为增长型。表明由低海拔向高海拔，黄山松种群处于不同的演替和发展阶段。

| Abstract: | By the method of spatial sere substituting for time sere, size structure in place of age structure,life stable and survival analysis, the structure and dynamics of Pinus taiwanersis population at different elevation on the Tianzhu mountain national forest park were studied. The result showed that, with the altitude increasing, the population density increased, distribution range of size class decreased, survival curves changed from Deevey Ⅱ type to Deevey Ⅰ type. It indicated that P. taiwanensis population at different elevations developed at different stages. |
