摘　　要：综合分析空心莲子草(Alternanthera philoxeroides)的入侵机制并探讨其防治方法,指出空心莲子草的成功入侵与其自身的生物学特性,如无性繁殖、较强的表观可塑性、广泛的适应性、强大的抗逆性等密切相关,其次与生境的可入侵性、人为干扰等外在因素也息息相关。应将人工防除与化学、生物防除手段相结合,加强区域间管理,适时适地采取最佳防除措施。需加强入侵种空心莲子草与本地种的竞争关系研究,运用本地种防止其入侵。Mechanism and control of the invasion of alligator weeds （Alternanthera philoxeroides） was discussed. It was concluded that the successful invasion of alligator weeds is not only associated with its specific biological characteristics, such as vegetative propagation, high phenotypie plasticity, extensive adaptability, strong stress resistance and so on, but also related to invasibility of the habitat it invaded, intensive human disturbance, lack of natural enemies and global cli- mate change. It is essential to integrate physical, chemical and biological means into its control strategy, intensify inter-re- gional management and adopt time- and site-specific optimal measures for the control. Specially, more attention should be paid to the research on competition relationship between the invasive alligator weeds and native species, for better use of the latter to control invasion of the former.
