根据杭州市实际情况,从用水效率、经济发展角度选取20个指标构建了评价杭州市用水效率与经济耦合协调发展的指标体系,采用熵权法对选取的评价指标进行权重计算,根据耦合协调模型分析了杭州市的用水效率与经济耦合协调发展情况。结果表明,杭州市处于粗放型用水阶段,用水效率与经济发展水平的相对发展度波动较大,主要与用水效率波动较大有关;耦合度在0.48~0.50之间,处于拮抗阶段,接近磨合阶段;耦合协调度处于0.40~0.50之间,并且越来越接近0.5,处于中度协调耦合阶段,并向高度协调耦合阶段过渡,用水效率与经济发展的协调发展趋势更加明显。
According to the actual situation in Hangzhou, from the perspective of water use efficiency and economic development, 20 indicators are selected to construct an index system for evaluating the coordinated development of water use efficiency and economic coupling in Hangzhou. The entropy weight method is adopted to calculate the weights of selected evaluation indexes. According to the coupled coordination model This paper analyzes the coordinated development of water efficiency and economic coupling in Hangzhou. The results show that the relative development degree of water use efficiency and economic development level fluctuates largely in Hangzhou, which is mainly related to the large fluctuation of water use efficiency. The coupling degree is between 0.48 and 0.50, which is in the antagonistic stage and close to the run-in stage ; The coupling coordination degree is between 0.40 ~ 0.50 and closer to 0.5, which is in the stage of moderately coordinated coupling and transition to the highly coordinated coupling stage, and the coordinated development trend of water use efficiency and economic development is more obvious.
