Evaluation of Human-Water Harmony Based on Coupled Coordination Model
In order to evaluate the relationship between human and water quantitatively,taking Xi'an City as an example,the evaluation in-dex system of human and water harmony was built on the basis of the concept of human and water harmony.The weights of each index were calculated by improving G1 weighting method.Based on the comprehensive development level of water system and human system,the cou-pling coordination model was used to calculate the coordination degree of human water system,and the obstacle factors were identified by the obstacle degree model.The evaluation method of single index quantification,multi-index synthesis and multi-criteria integration was adopted to calculate the health degree of effluent system and the development degree of human system,and then integrate with the coordination degree of human water system,and finally got the evaluation result of human water harmony in Xi'an City from 2012 to 2021.The results show that the man-water coordination degree of Xi'an City is gradually improved,and the obstacle degree of each index to the coordinated development of man-water system in each year is clearly visible,and the harmony of man-water is also improved from less harmonious to harmonious level.The evaluation results of this method are consistent with the actual results and have good applicability.The identification of obstacle factors is instructive to further improve the harmony between human and water.
