- Abstract
In order to deepen the recognition of the trend of synergistic evolution of water resources, energy, food and ecosystem in China, a water-energy-food-ecology multi-dimensional system index system was constructed, and the coupling coordination degree model was applied to evaluate the coupling coordination degree of water resources-energy-food-ecology from 2005 to 2020 in China, and the driving force analysis was conducted by using multi-factor attribution analysis. The results show that the coupling degree of water resources-energy-food-ecosystems in China has increased from 0.55 in 2005 to 0.84 in 2020, and the coupling degree of each region has transitioned from a barely coordinated development level to an intermediate coordinated development level, and the driving force for the increase of the coupling degree of the each subsystem has gone through the process of being dominated by food subsystem, ecological subsystem and the water resources subsystem; although the contribution of the energy subsystem is relatively smaller, it may be a breakthrough for the regions to improve the coordinated development level of the multidimensional system of water resources-energy-food-ecosystem in the future.
