Based on the fuzzy mathematics theory, the fuzzy comprehensive evaluation principle, the civil airport construction perimeter prevention system fuzzy comprehensive evaluation model. Perimeter prevention system of subsystems of fuzzy evaluation, in order to test the safety of each subsystem stability objective, comprehensive value will be divided into several respectively, and the corresponding to the organization of the airport four state, namely: crisis state [1,0.75], low state of crisis [0.75, 0.5], the basic normal [0.5, 25] and normal management state [0.25, 0]. When the calculated the comprehensive evaluation value in the above a certain range interval, can be directly shows the airport the perimeter security specific state.
