Abstract: Exotic plant invasion is an urgent global issue that threatens the sustainable development of ecosystem health. Its prevention is more effectual than treatment, and thus, the study of its ecological risk assessment could help us to prevent and reduce the invasion risk more effectively. Based on the theory of ecological risk assessment, and through the analyses of the characteristics and processes of exotic plant invasion, this paper discussed the methodologies of the ecological risk assessment of exotic plant invasion. The assessment procedure was consisted of risk source analysis, receptor analysis, exposure and hazard assessment, integral assessment, and working out of management measures. The indicator system of risk source assessment as well as the indices and formulas applied to measure the ecological loss and risk were established, and the method for comprehensively assessing the ecological risk of exotic plant invasion was worked out.
