摘　　要：广东是物种跨国界、跨洲界迁移最为密集的省份之一。南美蟛蜞菊是广东地区主要的外来入侵植物,对本土植物的生存及生态环境的稳定性造成严重威胁。广东地区南美蟛蜞菊的入侵可分为3个历史阶段:引进利用与逸生建群时期、大规模暴发与危害时期、防治与利用共存时期。南美蟛蜞菊在广东快速扩散蔓延主要因为盲目绿化种植,化感作用则是其造成危害的主要手段。Guangdong is a province with most alien species. Wedelia triloba L., which is the major invasive alien plant in the area of Guangdong, poses a serious threat to the native plants and ecosystem. Its invasion event in Guangdong can be divided into three periods： selective harboring and colonization during the introduction and utilization; large-scale outbreak resulted in serious environmental damages; the control and rational utilization. The rapid diffusion of wedelia in Guangdong is mainly due to blindly planting, causing harm primarily by allelopathy.
