摘　　要：入侵杂草肿柄菊对我国热带和亚热带地区的生物多样性和生态系统功能产生严重影响,且其入侵呈现快速扩张态势。为提高对肿柄菊入侵危害的认识水平,加强对肿柄菊的监测预警及防控,本文通过搜集、整理和分析相关文献资料,总结肿柄菊在世界各国不同地区的入侵情况及其影响,分析肿柄菊在我国入侵的历史、分布现状及其入侵对遗传多样性、物种多样性和生态系统多样性的影响。结合肿柄菊生态入侵防控研究与应用实践,指出肿柄菊入侵防控存在的主要问题和面临的挑战,并针对肿柄菊监测和高效防控技术体系提出高度重视肿柄菊入侵危害影响的分类风险评价、多元化开展肿柄菊入侵扩张的基础科学研究、建立早监测早预防的预警机制和构建针对肿柄菊入侵防控的综合技术体系等防控对策。The invasive weed,Tithonia diversifolia A.Gray poses a considerable threat to biodiversity and ecosystem function in the tropical and subtropical regions of China,due to its rapid expansion.To improve awareness of the impact caused by T.diversifolia,it is imperative to enhance monitoring,early warning,and control measures.This study is a thorough review of a range of literature.We present a comprehensive analysis of the impacts of T.diversifolia invasion and expansion across various countries and regions.The historical background and distribution and its impact on genetic,species,and ecosystem diversity are described.Combined with scientific research and application practices of the ecological invasion prevention and control technology of T.diversifolia,the main problems and challenges of the ecological invasion prevention and control technology of T.diversifolia are presented.To effectively monitor and prevent the ecological invasion of T.diversifolia,a multi-level risk assessment should be conducted.Diversified scientific research should be conducted on the expansion of the invasion.Early monitoring,prevention,and warning mechanisms should be established;and a comprehensive technical system for prevention and control should be constructed.
