区域外调水水权分配模型及应用

Study and application of water rights allocation model for regional transferred water

提出外调水水权分配的5项原则,以此建立外调水水权分配的多目标优化模型。该模型综合考虑了城镇生活、生产、生态用水,并且体现了水权分配的公平性、高效性、可持续发展等原则。通过确定各目标函数权重,将该多目标模型转化为单目标优化模型进行求解。目标函数权重的确定采用综合赋权法,应用熵权法确定各目标函数的数学权重,再结合决策者意向得出经验权重,最后通过线性加权得出综合决策的权重。该权重确定方法既尊重了客观实际又考虑了决策者的意向,使得模型应用更加灵活。最后,将该模型应用到大连市外调水水权分配中,结果显示该模型具有较好的实用价值,可以用来指导区域调水工程规划及水资源优化配置。

Five allocation principles for water rights allocation of transferred water are proposed. On this basis, the multi-object optimal allocation model is established for regional transferred water rights. The domestic water, process water and ecological water are comprehensively considered in the model, and it fully addresses fairness, effectiveness, and sustainable development of water rights allocation. In order to solve the model, the multi-object optimization model is transformed into a single-object one with a weighted method by the determination of the weights of objective functions. The weights of objective functions are determined by the comprehensive weight method. The objective weights axe obtained using the entropy weight method, and the subjective weights are obtained by analyzing the intention of decision-makers. The weights of the comprehensive decision are obtained by the linear weighting method. The model not only considers the real situation but also the intentions of the decision-makers, which makes it more flexible. Finally, the model is applied to water rights allocation in Dalian. The result shows that the model is valuable in practice, and it can be used to guide the planning of regional water transfer engineering and the optimal allocation of water resources.
