| 摘 要： | 对紫茎泽兰（Eupatorium adenophorum）和飞机草（Eupatorium odoratum）在广西入侵生境的植物多样性进行了研究。结果表明：在紫茎泽兰、飞机草发生危害的生境,Simpson指数、Shannon-Wiener指数、Pielou均匀度指数均比没有紫茎泽兰、飞机草危害的生境低。在紫茎泽兰样方中,有紫茎泽兰入侵的生境其上述各指数分别比没有紫茎泽兰入侵的低43.65%、55.13%、55.68%。而在飞机草样方中,有飞机草入侵的生境其上述各指数分别比没有飞机草入侵的低33.55%、37.78%、17.98%。说明紫茎泽兰和飞机草对入侵生境的植物多样性影响较大。

| Abstract: | Species diversity of plant communities of Eupatorium adenophorum and Eupatorium odoratum inhabit was measured by using the indices of species Simpson index,Shannon-Wiener index,Pielou index.The results showed that the relevant indices in Eupatorium adenophorum inhabit were lower than that in inhabit without the species by 43.65%、55.13%、55.68%.The indices in Eupatorium odoratum in inhabit were lower than that in habit without the species by 33.55%、37.78%、17.98%.It illustrate that the species diversity of plant communities of Eupatorium adenophorum and Eupatorium odoratum inhabit were comparatively reduced. |
