| 摘 要： | 对凹叶厚朴林分周边的马尾松、杉木、毛竹 3种不同林分类型的林冠下天然更新的凹叶厚朴幼树特性研究表明 :不同林分林冠下的凹叶厚朴幼树个体数量差异显著 ,以马尾松林分中数量最多 ,达 738株·hm-2 ,而对照厚朴林分下仅 2株·hm-2 幼树 ;凹叶厚朴个体空间分布格局经频次分布法测定 ,杉木、马尾松林内属奈曼分布和负二项分布 ,毛竹林内个体符合负二项分布 ;经扩散型指数测定 ,在马尾松、杉木、毛竹 3种林分类型内均属于聚集分布 |

| Abstract: | The study indicates that the individual amount difference of Magnolia officinalis under canopies of different stands is significant,the amount in Pinus massoniana stand is largest and 738 plants·hm -2 ,the amount under stand of control M.officinalis is only 2 plants·hm -2 ;the M.officinal individual spatial distribution pattern is determined with the frequency distribution method,the distributions in Canninghamia lanceolata and P.massoniana forests belong to Neyman distribution and negative binomial distribution,the individual in Phyllostachys pubescens forest accords with negative binomial distribution;through the diffusion index determination,the distributions in 3 stand types of P.massoniana,C.lanceolata and P.pubescens are all crowding distribution. |
