Abstract: Risk assessment of alien invasive species is the most effective and economically feasible way of preventing alien species. This paper sorts nine index factors including intentionally introducing, unintentionally introducing, environmental adaptation, environmental resistance, speed of growth, reproduction, proliferation, ecological environment and economic construction that have great influence on risk assessment, and analyzes the major risk factors in the assessment by using AHP analysis software Yaahp based on the external biological invasion, adaptability, proliferation, and harm.

Key words: alien invasive species, risk assessment, Yaahp software, AHP
