外来植物入侵机制初探

Studies on the Mechanism of Alien Plant Invasions

指出了外来植物入侵已成为破坏生态平衡,危及人类健康、妨碍社会发展的重大隐患,因此全面了解植物入侵的发生原因,掌握其发生机制是控制和预防植物入侵的重要前提。从三个方面阐述了植物入侵机制:(1)外来植物的侵染性功能性状;(2)新栖息地的可侵入性;(3)植物入侵的外部驱动力。深入剖析了植物入侵的外因和内因,并总结了植物入侵对生态系统、人类社会带来的主要危害,提出了防控措施和相关的建议。

Invasions of alien plants have become a major threat that destroys the ecological balance,endangers human health and hinders social development,thus to have a comprehensive understanding of the causes of plant invasion and its mechanism is an important prerequisite in control and prevention of invasive plants.In this paper,the mechanism of invasive plant was reviewed with respect to these three aspects：（1）Functional traits of alien plants contributing to successful plant invasions;（2）Invasiveness of new habitat;（3）External driving force of plant invasion.The paper dived deep into their internal and external causes,and reviewed the major hazard plant invasions do to the Eco-system and human society,proposing suggestions about prevention and control measures.
