Abstract: With the rapid development of urbanization, many cities are facing some problems related to water resources, such as, a serious shortage in freshwater, worse water environment, etc., it is an important approach for avoiding water resources crisis to improve water price system to promote water saving. Water resources value (WRV) is a very crucial factor involved in water price system. Many WRV models, such as the shadow price model, the marginal opportunity cost model, the supply-demand price model, and the fuzzy comprehensive judge model, have been proposed in the literature. The WRV system is a complex one with randomicity, fuzziness and is composed of three interactive subsystems of society, economy and environment. In this paper, aiming at the fuzzy characteristics of WRV, a fuzzy pricing model for urban water resources is proposed, which consists of a multi-criterion fuzzy evaluation model (I) and computation model (II) of WRV. In part I, various factors affecting WRV are comprehensively evaluated with multiple level and objective; in part II, the price vectors of water resources are constructed according to the definition of the endurance index of water price, then WRV is calculated. Finally, Jinan is taken as a case study to further testify the validness of the proposed model. The outcomes of this research indicate that the fuzzy pricing model for urban water resources is scientific, reasonable and practical.
