摘　　要：为了探讨不同栽培模式橡胶林的物种多样性,运用植物群落生态学方法,对云南省西双版纳州传统橡胶园、 改造型橡胶园和雨林橡胶园3种栽培模式橡胶人工林的结构、 种类组成和物种多样性进行了研究.结果表明,群落垂直结构复杂程度改造型橡胶园>雨林橡胶园>传统橡胶园;雨林橡胶园物种组成最为丰富,有维管束植物30科46属51种,改造型橡胶园有维管束植物25科34属34种,传统橡胶园植物组成最简单,有维管束植物14科16属19种,乔木层仅单一树种组成;乔木层橡胶树的重要值雨林橡胶园<改造型橡胶园<传统橡胶园;乔木层、 灌木层、 草本层的物种多样性指数在3种模式中都表现为雨林橡胶园>改造型橡胶园>传统橡胶园,改造型橡胶园和雨林橡胶园模式能显著增加乔木层的多样性指数.To explore the species diversity of Hevea brasiliensis plantation under different cultivation modes,community structure,species composition and diversity among traditional rubber plantation,modified rubber plantation and rain-forest rubber plantation were studied in Xishuangbanna of Yunnan province by using the method of plant community ecology.The results showed that the complexity of vertical structure of community was that modified rubber>rain-forest rubber>traditional rubber;the species composition of rain-forest rubber was the richest,there were 51 species of vascular plants belonging to 46 genera and 30 families;the modified rubber had 34 species of vascular plants belonging to 34 genera and 25 families,the species composition of traditional rubber was the lowest,there were 19 species of vascular plants belonging to 16 genera and 14 families,and only one species in the tree layer.The important value of tree layer in plantation was that rain-forest rubber<modified rubber<traditional rubber.The species diversity indexes of tree layer,shrub layer and herb layer in three models were that rain-forest rubber>modi-fied rubber>traditional rubber,modified rubber plantation and rain-forest rubber plantation could significantly increase the diversity index of tree layer.
