入侵植物互花米草防治：理念、技术与实践

lien Species Spartina alterniflora occupy the living space of native animals and plants, and lead to the reduction ofbiodiversity in the intertidal zone and wetland ecological service functions. Therefore, it is urgent to curb the rapid expansion of S.alterniflora in Chinas coastal areas. This paper introduced the invasion situation and main ecological hazards of S. alterniflora inChina, as well as put forward the concept of S. alterniflora control of hazard assessment zoning control monitoring and earlywarning. We summarized the control technologies of S. alterniflora at home and abroad and the current situation of S. alternifloramanagement in China. Different control technologies have their own advantages and disadvantages, and the integrated controltechnology combined with different technologies can usually achieve better control effect. As of early June 2023, China hasimplemented nearly 200 projects for controlling S. alterniflora, with most of the control costs being less than 60000 yuan per hectare.Finally, suggestions were put forward for future research: (1) combine prevention and control, and establish a long-term mechanism forthe control of S. alterniflora; (2) optimize integrated control technologies, and strengthen the research and development of professionalmachinery and equipment; and (3) strengthen the evaluation of the control efficacy of the control project and its impact on theenvironment and biodiversity.
