摘　　要：在再生水全成本价格模型中,需要计算再生水的资源成本。资源成本是一个模糊系统,其影响因素主要包括水质、水量、人均国内生产总值、人口密度等。选择COD、SS、氮、磷4项进行定量评价,建立隶属函数;水量、人均国内生产总值、人口密度是依据从全国大中城市中选择30个左右城市的数据,构建隶属函数。再计算出污水水资源价值的综合评价向量,转换为污水资源价格,即再生水的资源成本。It is necessary to calculate the resource cost in the all-cost price model structure of reclaimed water. Resource cost is a fuzzy system, and its impacting factors include water quality, water quantity, per capita GDP, population density, etc. Subject functions of water quantity, per capita GDP and population density may be set up according to the 30 cities data across the country. Then the synthetical vector and price of wastewater resource were calculated. The price of wastewater resource is the resource cost of reclaimed water.

关 键 词：再生水 资源成本 水质 水量
