| 摘要: |
| 该文分析了127种广州外来植物的种类及其生长型、原产地、现状、生境和季节变化。结果表明:具有较强繁殖能力的草本、灌木和藤本植物以及一些世界广布或热带性科属的植物和原产美洲、非洲的一些植物具有较强的入侵能力; 受人为干扰较强的路边、荒地、池塘、果园、菜园和人工林容易为外来植物入侵,而人为干扰较少的自然生境则不易为外来植物入侵。此外,文章对物种的入侵性和生境的入侵性问题进行了讨论,认为这实际上是一个问题的两个方面,物种的入侵性总是与被入侵的生境联系在一起并相互影响的。 |

| Abstract: |
| One hundred and twenty seven alien plant species of Guangzhou were reported in this paper,their growth forms,origin areas,status,habitats and changes in different seasons were analyzed. The results showed that alien plant species with strong reproductive ability such as herbs,shrubs,climbers were more invasive,especially those from America and Africa. Areas that were easier to be invaded always were those heavily interrupted or destroyed ecosystems,such as roadsides,pools and gardens. Further discussions suggested that the invasive species and easy-invaded areas were actually the two different sides of the same coin. Invasive species and invaded areas are related and interplayed. |
