Abstract

With the progress of society and economic development, the exchanges between countries are becoming more frequent and closer, and the spread and diffusion of species are becoming more and more common, which promotes the exchange and utilization of biological resources, but also inevitably causes the problem of invasion of alien species. The invasion of alien species poses a great threat to biodiversity, human health and economic development, so the identification of alien species invasion and the construction of risk prevention system are particularly important. Therefore, based on the definition of “biological invasion”, this study analyzes the harm of invasive alien species, and provides a method to identify whether it is an invasive species through the construction of analytic hierarchy process model and the analysis of actual cases, and then puts forward suggestions for constructing and improving the risk prevention system of species invasion.
