中文摘要：
采用连续样方法调查了梅花山保护区拟赤杨种群密度，以此为基础，计算了拟赤杨种群分布的偏离系数，并进行了种群的格局规模和格局纹理分析。结果表明：拟赤杨呈明显的集群分布；平均密度与偏离系数呈正相关；拟赤杨种群存在一个直径在15～50m的斑块（包括间隙）。
英文摘要：
The densities of Alniphyllum fortunei populations in different sites in Meihuashan Nature Re- serve were surveyed by the successive sampling method. The deviation coefficients were calculated and the pattern scale and pattern grain were analyzed. The results showed that the populations of A. fortunei were obviously clumpy distributed. Positive correlation existed between the population density and devia- tion coefficient. All the surveyed populations were found with a patch of 15-50 m in diameter including patch gap.
