澳门的外来入侵植物

Preliminarily Study on Invasive Alien Species in Macao

通过实地调查发现澳门有84种外来入侵植物。对外来植物的生长型、生境和原产地进行分析,结果表明:外来种对人为干扰的生态系统或群落结构简单的灌丛、荒草地等影响较大,而对复杂的自然生态系统影响较小;来源于热带美洲的外来种占绝大多数,这与两区区系的相似性、相似的生态环境和日益增长的经贸往来和生态旅游密切相关。

A survey of distribution and composition of invasive alien plant species in Macao was undertaken to provide a basis for management. And also the growth form, habitat, and origin area of exotic plants in Macao are discussed. The results show that: Most invasive aliens were associated with human activities, roadways and other disturbed ground. Close ecological and floristic relationship, similar climate, increased trade and eco_tourism are responsible for so many species introducing unintentionally or intentionally from tropical America.
