Research on the collaborative model and resource allocation of the water-energy-food system in the Yangtze River Delta:Based on the core position of water
Through multi-objective planning,the collaborative analysis framework of the water-energy-food system was established.Based on the dimension of Yangtze River Delta urban agglomeration,the cooperative model of the water-energy-food system was con-structed,and the deviation degree and economic benefit of the optimized composite system were calculated.The results showed that the comprehensive deviation degree of the water-energy-food system from 2001 to 2020 remained at a low level below 0.135,with large volatility and poor stability.From 2001 to 2020,both food output and energy exploitation maintained an upward trend,and food output was larger.In the early stage,energy exploitation was greater than the food output.After 2005,the food output increased rapidly,far exceeding the energy exploitation.The comprehensive benefit continued to rise,and the economic benefit of the synergistic model was relatively ideal.Accordingly,some suggestions of enhancing the linkage and symbiosis of the water-energy-food system,scientifically planning the integrated resource allocation project of water resources allocation,energy exploitation and food production,improving the overall input-output level of resources,and broadening the cross-regional flow path of resources were put forward.
