| 摘 要： | 应用α多样性和β多样性指数对东灵山地区辽东栎林在不同样地环境梯度的物种多样性进行了初步研究。结果表明:不同样地梯度的辽东栎林乔灌木物种α多样性逐步降低,但变化幅度较小,群落物种组成趋于简单。不同样地梯度内辽东栎林乔木物种的β多样性的二元属性测度与数量数据测度结果反映出乔木物种和灌木物种对整个辽东栎林多样性的影响是不同的。数量数据β多样性测度综合地考虑了物种数与物种数量对β多样性变化的影响,适于对单优群落物种多样性进行分析。在中海拔样地梯度,辽东栎林乔灌木物种各样地对之间的β多样性数值较小,表明辽东栎林内物种替代速率较低,物种组成相对稳定,总体上是比较稳定的林型。 |

| Abstract: | Based on environment gradient of different sample sites, the species diversity of Q. liaotungensis forest in Do ngling Mountain was studied primarily by α-diversity indexes and β-diversity indexes. The results showed that species α-diversity of arbors and shrubs species in Q. liaotungensis forest declined gradually along environment gradient of different quadrats but its changing range was less. Species constitute of forest inclined to simpleness. Based on environment gradient of different quadrats, different effects on β-diversity of overall Q. liaotungensis forest were revealed by arbor and shrub species diversity analysis with α-diversity indexes and β-diversity indexes. The species number and species quantity was adopted synthetically by β-diversity measure of quantitative data and this method was suited to analyze species diversity of dominant species community. During middle altitude gradient of quadrats, species β-diversity values were little between quadrat pairs of arbor and shrub species in Q. liaotungensis forest, which displayed that the species turnover rate of Q. liaotungensis forest was low and species constitute was stabilization to a certain degree. As a whole, Q. liaotungensis forest was stable forestry. |
