Based on the improved TOPSIS model, water resources carrying capacity research is carried out. On the basis of constructing a water resources evaluation index system, the weights are introduced from the traditionally constructed index matrix into the Euclidean distance of the TOPSIS model through subjective and objective weighting. When the ideal solution distance is the same, the larger weighted index corresponds to the greater water resources carrying capacity. The improved TOPSIS model is used to evaluate the water resources carrying. Taking Jinzhou as an example, we determine the advantages of water resources carrying capacity and the influencing factors of the short board in this area. The proposed method has certain theoretical and practical significance.
Résumé
Une recherche sur la capacité de recharge des ressources en eau est menée à l'aide du modèle TOPSIS amélioré. Sur la base d'un système d'indice d'évaluation des ressources en eau, les pondérations sont introduites à partir de la matrice d'indice traditionnellement construite dans la distance euclidienne du modèle TOPSIS par une pondération subjective et objective. L'indice pondéré le plus élevé correspond à la plus grande capacité de recharge. Une application de la méthode est donnée sur la région de Jinzhou.
