[Aim] With the development of international trade of agricultural products, exotic weed invasions has become more and more serious in China. We Investigated and monitored the alien weeds in imported grain shipments at Huizhou, in order to portpropose recommendations of control and management measures against alien weed in Huizhou port.[Method] Based on field surveys, monitoring and literature review, this paper summarises the composition, distribution, life forms, regions of origin, invasion routes and damage of alien invasive weed species intercepted at Huizhou port.[Result] We found 28 species from 12 families of alien invasive plant species, including 4 quarantine species, in and around the import grain storehouse areas of Huizhou port. Species in the Compositae family had the highest percentage of invasive weeds species, most of which originated from the Americas and were introduced unintentionally by humans; annual herbs were the dominant life form. There were 7 species with great potential threat to the local ecological environment.[Conclusion] This study is the first comprehensive survey, and produced a list of invasive weeds in imported grain storage areas.
