    On Water Resource Carrying Capacity Evaluation of Kaifeng City Based on PCA(Principal Component Analysis) and Entropy Weight Method

      Graphical Abstract
      • Abstract
    • In order to scientifically allocate and utilize the water resource of Kaifeng city, the evaluation index system of water resources carrying capacity of Kaifeng city was established based on PSR model.Four principal components affecting the carrying capacity of water resources of Kaifeng city were extracted by PCA (Principal Component Analysis).The Entropy Weight Method was used to calculate the weight of the principal components,then to build a comprehensive evaluation model of the water resource carrying capacity of Kaifeng city.This model obtained the main factors of affecting water resource carrying capacity.
