Abstract:
The evaluation index system of water security was developed using the Analytic Hierarchy Process (AHP) method. On the basis, a water security model was established using the projection pursuit method, and applied to perform the comprehensive evaluation of water security in the Lower Liao River Plain on the regional scale. The results showed that water security is safe in Fushun and Li 2 aoyang, relatively safe in Shenyang and Anshan, andunsafe in Jinzhou, Yingkou, Tieling, and Panjin. The water security evaluation mod2 el based on projection pursuit method is applicable and can be applied to assess regional water security.
