[Objectives] The paper was to investigate and assess the species, distribution and hazard status of invasive alien plants on the campus of Tongren University. [ Methods] A survey was conducted using line survey method, and the risk assessment index system of invasive alien plants was established by analytic hierarchy process (AHP). [Results] There were 11 species of invasive alien plants on the campus of Tongren University, belonging to 8 genera and 5 families. There were 6 species of invasive alien plants belonging to Asteraceae, accounting for 54.55% of the total. In terms of the origin of invasive plants, most of them were native to North America and Europe, accounting for 27.27% of the total. In terms of harmful level, there were no high-risk invasive plants on the campus of Tongren University, but Altemanthera philoxe-roides had the highest score and was the most harmful. [Conclusions] The present situation of alien plant invasion on the campus of Tongren University is closely related to the ecological environment of the campus. It is suggested to strengthen the management of campus plants, focus on the prevention and control of A. philoxeroides, and carry out regular investigation of invasive alien plants on campus to ensure the ecological safety of the campus.
