| 摘 要： | 为探讨丹霞地貌区常绿阔叶林群落物种多样性,通过对物种丰富度指数、物种相对多度模型、物种多样性指数和物种均匀度指数的测度,对区域内16个常绿阔叶林群落进行分析,并与中亚热带典型地区森林群落物种多样性比较。结果表明,万佛山常绿阔叶林群落具有较高的物种丰富度,物种多样性在层次中的变化趋势为灌层〉乔层〉草层;万佛山常绿阔叶林生物多样性在中亚热带常绿阔叶林生态系统中具有普遍的意义。 |
| 关 键 词： | 丹霞地貌 常绿阔叶林 物种 相对多度 多样性指数 中亚热带 |

| Abstract: | The species diversity of 16 evergreen broad-leaved forest flora in Wanfo Mountain Danxia physiognomy area were analyzed by measuring the species richness index,diversity index,uniformity index and species abundance model,compared with species diversity of forest flora in mid-subtropical typical zone.The results showed that,evergreen broad-leaved forest flora in Wanfo Mountain had higher species richness.The changing trend of species diversity in the different layers was shrub synusia〉arbor synusia〉herbage synusia.The biological diversity of Wanfo Mountain evergreen broad-leaved forest had universal representative in the mid-subtropical evergreen broad-leaved forest ecosystems. |
| Keywords: | Danxia physiognomy evergreen broad-leaved forest species relative abundance diversity index mid-subtropical |
