| 摘 要： | 以各个植被样地为对象，采用物种丰富度、Simpson指数、Shannon-wiener指数及Pielou指数，研究了青城前山森林植被的物种多样性。结果表明：（1）在对青城山森林植被样地的物处多样性进行测度时，上述4种指标表现出相同的变化趋势。（2）不同层次的物种多样性的大小依次是：灌木层、乔木层和草本层。（3）不同植被类型物种多样性的大小是常绿阔叶林大于暖性针叶林。（4）人为因子的干扰对青城山森林植被的物种多样性有较大的影响。 |

| Abstract: | Based on data of plots, it was discussed about species richness, Simpson index, Shannon wiener index and Pielou index of the forest communities in Qingcheng mountain of Sichuan province. The results were similar when the four indices were used to measure species diversity of forest communities. The indices were compared for different vegetation types. Generally, the species diversity indices order was that shrub layer ,tree layer ,herb layer. The indices order was evergreen broadleaved forests and warm conifer forests. Human being affected the species diversity of forest communities. |
