山东省2011年～2020年水-能耦合协调特征分析OA

Water and energy are closely related.The continuous development of society greatly increases the demand for these resources,which leads to certain resource supply and demand problems in the process of economic development in Shandong.In order to better promote the harmonious development of the two resources,a comprehensive evaluation index system is established,and the coupling coordination degree model is used to analyze the coupling relationship between water and energy in Shandong from 2011 to 2020.The results show that the comprehensive evaluation index of water-energy system shows an increasing trend,and the fluctuation of water resources system is greater than that of energy system.The coupling degree is mostly in the running-in stage,and the coupling coordination degree shows a transitional trend,which is in the dynamic change of mild dissonance,barely coordination and primary coordination.
