摘要: 根据对缙云山针阔混交林群落更新层的样带调查数据,采用Margalef物种丰富度指数(R)、Simpson多样性指数(D)、Shannon-Wiener指数(H)、Pielou均匀度指数(J)及Alatolo均匀度指数(E)来研究更新层物种多样性的林隙梯度变化。结果表明:从非林隙到林隙中心,更新层物种多样性逐渐升高,即非林隙<林隙边缘<林隙近中心<林隙中心;物种丰富度变化与其一致,而均匀度变化则表现为两端高中间低的现象;更新层物种多样性林隙梯度变化程度受林隙发育阶段的影响较大,随着林隙的发育,变化程度为早期林隙>中期林隙>晚期林隙

AbstractTo research the species diversity change of the regeneration layer in gap gradients, we computed the Margalef index, Simpson diversity index, Shannon-Wiener index, Pielou evenness index and Alatolo index with the data from transects through the regeneration layer in a coniferous-broadleaved forest in Jinyun Mountain. Species diversity of the regeneration layer gradually increased from non-gap to the gap central area, such that: Non-gap Middle phase gap > Late phase gap.
