Abstract:

The invasion of alien animal has caused serious impacts to biodiversity,economy,and human health in China.Assessing correctly the spreading risk of invasive animals is significant for controlling them.On the basis of the analytic hierarchy process,this article set up a risk evaluation index system of the invasive animals proliferates among various provinces in China,and some typical animals,like 〖WTBX〗Pygocentrus nattereri〖WTBZ〗 and 〖WTBX〗Bactrocera dorsalis〖WTBZ〗 etc,were assessed and established a spread risk calculation model to calculate the spread risk，through setting up threshold to classify the spread risk of different animals into four degrees:Extremely high risk,High risk,Moderate risk,and Low risk.In the end,corresponding policy suggestions to each rank,in order to improve management efficiency for government were raised
