[Aim] The range expansion of alien species causing ecological problems in newly invaded regions is of great concern for managers. The South-to-North Water Division project can provide new channels leading to the spread of invasive species.[Method] The study analyzed the potential of invasion of plants found in the shortlist of alien invasive species under national key management. An index was developed for comprehensive risk assessment of invasive alien species. The systematic risk assessment of 24 invasive plants spreading northward along the South-to-North Water transfer channel in the Beijing-Tianjin-Hebei region was carried out.[Result] Except for Ageratina adenophora and Spartina alterniflora with relatively low value of risk (R<0.6), the risk values of the remaining 22 invasive plants are all high (R>0.6), among which three invasive aquatic plants, Alternanthera philoxeroides, Eichhornia crassipes and Pistia stratiotes, have the highest risk levels (R>0.8).[Conclusion] The project may promote the spread of invasive plants to the north and eventually invade the Beijing-Tianjin-Hebei water receiving area. It is recommended that early monitoring and warning measures should be taken to prevent and control the spread of invasive species along with the project.
