摘　　要：外来植物入侵是物种灭绝和生态系统退化的重要驱动因素之一,通常来说,成功入侵的植物通常比不成功入侵的植物具有更强的适应能力、繁殖能力和波动性。繁殖生物学特性的研究将有助于揭示生物的入侵机制,控制入侵物种的扩张。外来入侵植物的表型可塑性和遗传分化两大策略,有助于其适应异质性生境,利用化感作用加上高效的资源利用性竞争使其更具入侵性。Invasive plants are one of the most important drivers of species extinction and ecosystem degradation.It is generally accepted that successful invasive plants are generally more adaptable,reproductive,and volatile than unsuccessful invasive plants.The study of reproductive biology will help to reveal invasion mechanisms and control invasive species.Phenotypic plasticity and genetic differentiation are two major strategies for invasive alien plants,which help them adapt to heterogeneous habitats and make them more invasive by using allelopathic interaction and efficient competition for resource utilization.
