| 摘 要： | 在了解入侵种紫茎泽兰个体发育规律等生活史特征的基础上对比其与当地植物种类在物候学上的差异,发现紫茎泽兰的入侵主要是由于个体发育过程中与大多数本土植物存在明显的时间差。提出在防控其入侵蔓延的实践中,除了保护生态系统的健全与完整以外,应该优先选择与之物候学特征相近的本土植物进行替代治理与预防,实现有效控制紫茎泽兰的入侵危害。 |

| Abstract: | This characteristics of ontogenesis and phenology of Crofton weed(Eupatorium adenophorum) and the local plants were compared and it was found that the main cause of the invasion is the temporal differences between the weed and the local plants,i.e.,during the period when the local plants shed their leaves or died off in the dry season,the weed kept growing;thus the seedlings of Crofton weed took the temporal differences to develop continually,and when the rain season came,the seedlings have established and ... |
