Abstract:Alien Species Spartina alterniflora occupy the living space of native animals and plants, and lead to the reduction of biodiversity in the intertidal zone and wetland ecological service functions. Therefore, it is urgent to curb the rapid expansion of S. alterniflora in China’s coastal areas. This paper introduced the invasion situation and main ecological hazards of S. alterniflora in China, as well as put forward the concept of S. alterniflora control of “hazard assessment – zoning control – monitoring and early warning”. We summarized the control technologies of S. alterniflora at home and abroad and the current situation of S. alterniflora management in China. Different control technologies have their own advantages and disadvantages, and the integrated control technology combined with different technologies can usually achieve better control effect. As of early June 2023, China has implemented 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 for the control of S. alterniflora; (2) optimize integrated control technologies, and strengthen the research and development of professional machinery and equipment; and (3) strengthen the evaluation of the control efficacy of the control project and its impact on the environment and biodiversity.
