2000-2020年黄河流域水—能源—粮食系统耦合协调时空演变特征
SpatioTemporal Characteristics of Water-Energy-Food Coupling Coordination in the Yellow River Basin in the Period from 2000 to 2020
摘要
Abstract
[Objective]The aims of this study are to explore the coordinated spatiotemporal evolution of water-energy-food system in the Yellow River Basin,and to provide scientific basis for quantitative evaluation of high quality development and regional sustainable development.[Methods]Through the coupling coordina-tion degree model,the comprehensive development level and coupling coordination characteristics of water-energy-food system were analyzed.And the grey correlation degree was used to sort the internal indicators of each subsystem,and then the influence degree on the coupling coordination degree of water-energy-food system was judged.[Results](1)The integrated development index of the water-energy-food system in the Yellow River Basin showed an increasing trend,and the fluctuationof water resources subsystem was the largest.(2)The coupling coordination degree of water-energy-foodsysteminthe Yellow River Basin developed from primary coordination to good coordination stage during 2000-2020.From the perspective of space,the development level of coupling coordination degree between different provinces and regions was significantly different,which could be shown as the upstream region>the middle and downstream region.(3)The ranking of the influence degree of the coupling coordination degree of each subsystem and system could be expressed as water resources subsystem>food subsystem>energy subsystem.The correlation degree between the internal factors of the water resources system and the coupling coordination degree of the system was above 85%.The strict management of the water resources system was particularly important compared with other subsystems.[Conclusion]The coupling and coordinated development level of water-energy-food system needs to be improved.In order to promote the coordinated development of the system and the high-quality develop-ment of the basin,the interaction of subsystems should be considered comprehensively.关键词
