通过对华南地区阔叶次生林和桉树人工林的林下植物多样性进行调查对比分析，发现次生林林下植物123种，分属52科；桉树人工林林下植物102种，分属49科，两者数量上相差不大，相同的有64种。2个生境物种构成不同，次生林的丰富度指数、均匀度指数、多样性指数均略高于桉树人工林，方差分析显示两者各样方林下植物分布差异显著。2种生境中重要值前10的物种只有3个相同，两者林下植物重要值都集中在前10个物种中，均约占一半。总体上桉树人工林林下植物多样性与次生林的相近。

This study investigated the diversity of undergrowth plants growing under secondary broadleaf forest and under Eucalyptus plantations in southern China. Under secondary forest 123 undergrowth species were found and these represented 52 families whilst in Eucalyptus plantations 102 undergrowth species were found these represented 49 families. There were 64 undergrowth species in common between the secondary forest and Eucalyptus plantations, indicating that species structure was different between these two forest types. Measures of diversity for the understory species including richness index, evenness index and diversity index for secondary forest were slightly higher than those for Eucalyptus plantations. Analyses of variance revealed significant differences between the understory plants of these two habitats. There were only three species in common between the top 10 species ranked by Importance Value in each of the two habitats. Even so, the diversity of undergrowth plants of Eucalyptus plantations was similar to secondary forest.
