The results show that there are more than 70 species of non-native plants in the Three Gorges Dam area, of which about 60% are invasive species. The invasive plants mainly distribute in water edges and areas with frequent human activities, which occupy the local ecological resources and do harm to the local ecological environment. Meanwhile, due to the decreasing water level of the reservoir and the activities of afforestation and gardening by local residents, more non-native plants will be introduced. Therefore, related measures should be taken to strengthen the monitoring and control of non-native plants and protect the local ecological environment.Keywords: Three Gorges Dam, non-native plants, invasive risk, ecological environment
