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 collected from the plots, the spatial distribution pattern of Pinus tawnensis population in different communities was fitted by using the theory of discrete distribution, the determination of aggregation intensity index and the pattern texture analysis. The results showed that: the Pinus taiwanensis juvenile tended to aggregate distribution, and then gradually transition to a random distribution. Mainly due to intraspecific, interspecific competition and light and other factors. The formation of spatial distribution pattern of different forest types is also related to soil, light, altitude and other factors.
