黄山松空间分布格局的研究

A STUDY ON THE SPATIAL DISTRIBUTION PATTERN OF PINUS TAIWANENSIS HAYATA

以样地调查数据为基础，应用离散分布的理论拟合、聚集强度指数的测定和格局纹理的分析方法，对不同群落中黄山松种群空间分布格局进行拟合分析。结果表明：黄山松幼年期趋于聚集分布，以后逐渐过渡到随机分布。主要由于种内、种间竞争及光照等因子的作用。而不同林型空间分布格局形成也与土壤、光照、海拨等因子影响有关。

Based on the data of sample field investigation and the theory of discrete distribution and the aggregation indensity, thes artcle provides an analysis of the spatial distribution pattern of Pinus taiwanensis Hayata. The result shows that the population tends to distribute clumpingly at its juvenile period and then comes to distribrte randomly. The distribution pattern results mainly from the competition of population, soil, sunshine, elevation and their like.
