- 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 coordination 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 development of the basin, the interaction of subsystems should be considered comprehensively.
