Comprehensive Evaluation on Exploitation and Utilization of Water Resources Based on Improved Fuzzy Pattern Recognition Model

Through identifying the exploitation and utilization of water resources system, this paper establishes an improved fuzzy pattern recognition model by combining fuzzy matter-element model with the improved entropy evaluation method and sets up the comprehensive evaluation index system which includes 3 layers and 10 indicators from two aspects: water utilization efficiency and water ecological environment. The proposed model and evaluation index system are applied to evaluate the comprehensive exploitation-utilization grade in Shandong Province. Results show that the exploitation-utilization of water resources and water ecological environment are not balanced in Shandong province, this indicates that the growth of ecological benefits and the protection of water ecological environment are ignored in the process of water resources exploitation-utilization.
