| 摘 要： | 分别运用Shannon—Wiener指数和物种均匀性指数探讨了濒危植物长柄双花木群落的物种多样性。研究结果表明,长柄双花木群落物种多样性水平随海拔高度下降而呈上升趋势。乔木层物种多样性与群落稳定性有关,随群落稳定性增加多样性指数升高;而草、灌层物种多样性则以乔木层盖度高及群落生境优越者高。

| Abstract: | The species diversity of endangered plant-Disanthus Cercidifolius Maxim. Var. longipes H.T. Chang is studied with Shannon-Wiener index and even index. The studied results show that, the species diversity of Disanthus Cercidifolius Maxim. Var. Longipes H.T. Chang is increasing with the elevation decreasing. The species diversity of tree strata relates to the community stability, and with the stability the diversity index going up. But the species diversity of bush strata and herb strata with more cover of tree strata and well community habitats is high. |
