水资源价值是指水资源使用者为了获得水资源使用权需要支付给水资源所有者的货币额，它与水价是不同的概念，合理的水价应包括水资源价值。目前可以用来求算水资源价值的模型不同程度地存在各种问题，必须加以完善和发展。影子价格模型只反映水资源的稀缺程度和水资源与总体经济效益之间的关系，其结果不能代替水资源价值；边际机会成本模型存在着应用困难较大、替代选择多样性、结论缺乏可比性、忽略了水质等问题；供求价格模型仅仅通过水资源量决定水资源价值是不科学的；模糊数学模型是潜力较大的最新模型，其缺点是影响水资源的各项因素的模糊评价较复杂，权重的确定是多样的。
The value of water resources refers to the amount of money that water users need to pay water resource owners in order to obtain water use rights. It is different from water price. Reasonable water prices should include the value of water resources. At present, the models that can be used to calculate the value of water resources have various problems to various degrees and must be perfected and developed. The shadow price model reflects only the scarcity of water resources and the relationship between water resources and the overall economic benefits. The results can not replace the value of water resources. The marginal opportunity cost model has many problems, such as large application difficulties, , Ignoring water quality and other issues; supply and demand price model is only unscientific decision by the amount of water resources; fuzzy mathematical model is the latest model with great potential, the disadvantage is that the fuzzy evaluation of the various factors affecting water resources more complex The weight determination is varied.
