摘要
为综合考虑经济效益、虚拟水消耗量、人均用水公平性差异以及营养学因素在地区农畜产品生产规划中的作用,研究了基于虚拟水及营养学的水资源优化配置问题。建立了经济效益最大化、虚拟水消耗量最少、人均用水公平性差异最小并满足营养学约束的多目标优化模型。用可变模糊决策理论求解模型,得到最佳的各类农畜产品生产方案。以石羊河地区各数据为例对模型进行仿真,结果表明所得到的方案是综合性能最优的方案。
In order to consider the importance of the economic benefit, virtual water consumption, fairness difference of water use per person, and nutrition factors in the regional planning of production of agricultural and livestock products, the optimized allocation problem of water resources based on the virtual water and nutrition was studied. A multi-objective optimization model with the maximum economic benefit, the minimum fairness difference of water use per person, and the minimum virtual water consumption, meeting the constraints of nutrition factors, was established. The model was solved using the variable fuzzy decision-making theory and an optimal scheme for production of each kind of agricultural and livestock product was obtained. The model was run based on data from the Shiyang River Basin, and the results show that the scheme obtained from the model is the optimal scheme.
