Comprehensive Evaluation and Analysis on Water Resources Carrying Capacity Based on Entropy and Principal Components in Shanxi Province

Take Shanxi Province as an example, the index system for evaluation of water resources carrying capacity is suggested. On this basis, the comprehensive principal analysis method for assessing the water resources carrying capacity and a multivariate linear regression model for corresponding driving factors of water resources carrying capacity are established. The analysis on sampling shows that it obeys the law of normal distribution. The corresponding standards for assessment are deduced accordingly. The application shows that the proposed method can comprehensively reflect the water resources carrying capacity.
