摘  要:
随着大面积规模化的种植,桉树人工林结构过于简单,林下植物多样性低的问题不容忽视。通过对普洱地区桉树人工林与同等条件下的天然林植物种类进行比较,桉树人工林群落物种数量流失,多样性下降和外来物种的入侵,说明一旦种植桉树以后,原有的生态系统都完全改变了,单一栽培桉树树种通常都造成了物种多样性的减少。

摘  要:
We can not ignore the problem on simple structure and poor diversity of understorey vegetation with the large-scale cultivation of eucalyptus plantation.By comparing the plant diversity situation of eucalyptus plantation in Puer region with other biomes that the same condition,we find out that the number of eucalyptus plantation community species are losing,the plant diversity are declining and invasive species are appearing.It tells us that once we plant eucalyptus,the ecosystem there will totally be changed.The monoculture of eucalyptus will usually lead to species diversity decreasing.
