摘要：合理的水价体系在水资源优化配置中扮演着至关重要的角色。本文提出了城市水资源模糊定价模型，此模型由多标准模糊评估模型和水资源价格（WRP）计算模型构成。其中，多标准模糊评估模型对影响WRP的各因素进行了多层次、多目标的综合评估，WRP计算模型根据可承受水价指数的定义，构建了水资源价格向量并计算了水资源价格。由于模型使用者自身知识的差异，本模型加入了迭代权重并考虑了使用者对权重估计的主观偏好，以此确定的权重更合理、评估结果更符合实际。特别地，研究过程中考虑了分质供水。不同水质的水区别定价符合水资源价值规律（WRV）。最后，提出了优质地下水价格计算模型以满足水资源优化配置及提高生活水平的需求。该模型的有效性已在济南市得到了验证。文中所用方法也为水资源价格研究提供了新的途径。

Abstract: A rational water price system plays a crucial role in the optimal allocation of water resources. In this paper, a fuzzy pricing model for urban water resources is presented, which consists of a multi-criteria fuzzy evaluation model and a water resources price (WRP) computation model. Various factors affecting WRP are comprehensively evaluated with multiple levels and objectives in the multi-criteria fuzzy evaluation model, while the price vectors of water resources are constructed in the WRP computation model according to the definition of the bearing water price index, and then WRP is calculated. With the incorporation of an operator's knowledge, it considers iterative weights and subjective preference of operators for weight-assessment. The weights determined are more rational and the evaluation results are more realistic. Particularly, dual water supply is considered in the study. Different prices being fixed for water resources with different qualities conforms to the law of water resources value (WRV) itself. A high-quality groundwater price computation model is also proposed to provide optimal water allocation and to meet higher living standards. The developed model is applied in Jinan for evaluating its validity. The method presented in this paper offers some new directions in the research of WRP.
