| 摘 要： | 对思茅松工业人工林的不同混交配置模式的植物多样性及其与思茅松主要害虫的发生程度之间的关系进行了研究.思茅松与红木荷、西南桦或高阿丁枫的混交林以及栽松留阔的思茅松人工林的Shannon指数显著高于思茅松纯林.思茅松工业人工林乔木层的植物多样性越大,则思茅松的主要害虫思茅松松毛虫、微红梢斑螟、松实小卷蛾等的危害程度越低.在思茅清水河各种配置的思茅松混交林中,其乔木层的Shannon指数与思茅松毛虫及微红梢斑螟的危害率呈良好的线性关系.

| Abstract: | Plant diversity of different deposition model of industrial plantation of Pinus kesiya and the relationship between the plant diversity and insect pest occurence degrees was studied.Shannon index of mixed stands of P.kesiya with Schima wallichii,or Betula alnoides,or Altingia chinensis and stands of models of planting pine with keeping broadleaf trees were higher than those of pure P.kesiya stands.Higher plant diversity in the tree layer resulted lower occurrence degrees of the main pest of P.kesiya such as... |
