| 摘 要： | 从生物多样性保护的原则出发 ,对乳源木莲天然林群落生物多样性进行测定 ,结果表明 :群落的物种比较丰富 ,乔木层、灌木层和乔木层 +灌木层的物种——多度符合 Weibull分布 ;相对于其它各层 ,乔木层的多样性指数、丰富度和优势度指数均较大 ,均匀度较小 ;在考虑样地面积对多样性指数影响和精确反映群落物种的多样性方面 ,Shannon- wiener指数要优于Mclntoch指数 |
| 关 键 词： | 乳源木莲 生物多样性 群落 Weibull分布 |

| Abstract: | Based on the principle of the protection of biological diversity,the biological diversity in a natural forest of Manglietia yuyuanensis community was measured.The results shows that the species in community are considerably rich,the species abundance of the tree layer,shrub layer and the stratum+shrub layer correspond with Weibull distribution;Compared with other layers,the species diversity index,species richness index and dominant index of the stratum layer are higher,but the evenness is lower.When considering the effect of plots area on the species diversity and the accuracy of measuring the species diversity in community,the Shannon wiener index is better than Mclntoch index. |
| Keywords: | Manglietia yuyuanensis species diversity community Weibull distribution |
