摘　　要：为促进水资源的节约、保护和优化配置,选取完全成本法作为区域水权交易基础价格的核算方法,对水权交易基础价格的各要素核算模型进行完善。该核算方法增加了生态补偿水价模型,基于生态系统服务功能价值来测算生态补偿水价,引入补偿系数确定应予补偿的生态系统服务价值;充分考虑了资源性稀缺和水质性稀缺,对资源水价进行修正;将单位水资源排污费加上污水处理设备投入费用作为单位水权的环境水价测算方法;基于交易期限与节、输水工程使用寿命的长短比较,分别讨论工程水价。以巴彦淖尔市与乌海市区域水权交易为例,测算出巴彦淖尔与乌海之间的区域水权交易基础价格为1.20元/m^(3),高于当前交易价格,反映出目前水权交易确定基础价格时对生态补偿考虑欠缺。In order to promote the conservation,protection and optimal allocation of water resources,the full-cost method is selected as the accounting method for the basic price of regional water right transaction.The accounting model for various elements in the basic price of water right transaction is improved.The model for ecological compensation water price,which is calculated based on the value of ecosystem service function,is added,and the compensation coefficient is introduced to determine the value of ecosystem services to be compensated.The resource scarcity and the water quality scarcity are fully considered to correct the water price of resources.The cost of sewage disposal per unit of water resources and the cost of sewage treatment equipment are taken as the measuring method for the environmental water price per unit of water rights.Based on the comparison of the transaction time and the service life of water transfer projects,the water price is discussed.Finally,for the case studies of the regional water right transaction of Bayannur City and Wuhai City,the basic price of the regional water right transaction between Bayannur City and Wuhai City is calculated to be 1.20 yuan/m 3,higher than the current transaction price,reflecting the lack of consideration of the ecological compensation in determining the basic price of the current water right transaction.
