摘 要: 研究了多竹种混交、竹桉混交和竹橡胶混交对林木生长及林分土壤条件的影响。 结果显示:不同竹种
混交以及竹树混交其林木生长状况及土壤条件均优于纯林;竹子纯林、多竹种混交林、竹树混交林3 种不同类
型的林分其土壤含水量和有机质含量排序为:多竹种混交林竹子纯林竹树混交林乔木纯林。 研究结果
表明,在桉树林和橡胶林中适当套种竹子可以改善桉树林和橡胶林的生长环境,增强生态系统的稳定性,对于
维护生态平衡、提高林地生产力、维持土壤肥力具有显著作用。 研究结果可为桉树和橡胶树纯林的改造提供理
论支持。

Abstract:This paper studied the effect of mixed forest of various bamboo species,mixed bamboo-eucalyptus forest
and mixed bamboo-rubber forest,on the growth of forest tree and stand soil condition. The results showed that the
forest trees in mixed forest of various bamboo species and mixed bamboo-arbor forest grow better than those in pure
forest with better soil condition;the moisture content and organic matter content in the soil of pure bamboo forest,
mixed forest of various bamboo species and mixed bamboo -arbor forest could be ordered as mixed forest of various
bamboo species pure bamboo forest mixed bamboo-arborforest pure arborforest. The research showed that
the inter-cropping of bamboo in eucalyptus and rubber forest could improve the growth environment of these forests,
enhance the stability of these ecosystems,and play a significant role in maintaining eco -balance,improving forest
