摘要： 为了计算张掖市水资源价格，对张掖市水资源数量、水价制度及经济状况进行了实地调查。通过建立张掖市水资源价值模糊评价模型，采用升（降）半梯形函数确定了模糊评价的一元线性隶属关系，选取了水质、人均水资源量、人口密度、人均国民生产总值作为评价指标，综合评价了张掖市的水资源价值。结果表明：张掖市的资源水价为1.97元/m3，相应的居民自来水价应为2.347元/m3，是现行居民用水价（0.85元/m3）的2.76倍。且根据现行水价，每人每年需支出水费126.74元，占人均居民可支配收入（14395元）的0.88%，远低于模型中的控制指数0.015。因此，政府相关部门应加快水价制度改革，重新制定水费收取标准，从而实现水资源的优化配置。

Abstract: In order to calculate the water resource price of Zhangye City, the author carried out a field investigation about the quantity of water resources, water price system and the economic situation of Zhangye City. By establishing the fuzzy evaluation model of water resource value in Zhangye City, the author used rise (drop) half trapezoid function to determine the value of water resources for the evaluation of fuzzy linear subordinate relations, selected the water quality, per capita water resources, population density, per capita gross national product (GNP) as evaluation indexes, and conducted the comprehensive evaluation of water resource value of Zhangye City. The results showed that the water resource price was 1.97 yuan/m3 in Zhangye City, the corresponding tap water price for residents should be 2.347 yuan/m3, which was 2.76 times of the current residents’ water price (0.85 yuan/m3). And according to the current water price, annual expenditure on water was 126.74 yuan per person, accounting for 0.88% of per capita disposable income (14395 yuan), far lower than the control index in the model 0.015. Therefore, relevant government departments should accelerate the reform of water price system and re-enact fee collection standards, so as to realize the optimal allocation of water resources.
