| 中文摘要: |
| 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。 |

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. |
