| 摘 要： | 在样地调查的基础上研究了井冈山不同经营类型毛竹种群胸径概率分布规律。结果表明:纯林毛竹径级分布服从正态分布和威布尔分布,密度函数曲线呈对称钟形,略有左偏;混交毛竹径级分布服从正态分布,密度函数曲线呈对称钟形,略向右偏;且混交林平均胸径大于纯林平均胸径。这对研究毛竹林分结构规律以及对毛竹林进行科学经营具有一定的理论和实际意义。 |
| 关 键 词： | 毛竹种群 径级分布 井冈山自然保护区 |

| Abstract: | Based on quadrats investigation,the diameter structure of Phyllostachys edulis in Jinggangshan National Nature Reserve was studied in this paper.The result showed that diameter probability density function of DBH of Phyllostachys edulis in pure forest was modeled by a normal distribution and a weibull distribution,a bell-shape curve and left-direction-deflection,and that mixed fores was normal distrbution,showing right-direction-deflection.And the mean DBH in mixed forest was larger than that in pure forest.These would be certain theoretical and practical signficance for scientific management. |
| Keywords: | Phyllostachys edulis DBH distribution Jinggangshan National Nature Reserve |
