摘　　要：水价与农业节水和农民利益紧密联系,合理的农业水价能够减少水资源量使用、提高用水效率,达到节水目的。以博爱县为研究区,利用水足迹理论,计算P=75%水文年作物生产水足迹,在避免浪费和浇灌不彻底条件下,核算作物灌溉用水量。计算结果显示,小麦的产品水足迹是0.632 m3/kg,玉米的产品水足迹是0.622 m3/kg,将蓝水足迹折算为基础水价,得到基础水价为0.23元/m3;为便于水费收取和管理,将其折算为抽水电费,得到终端水价,即基础电费1.33元/k Wh。同时可结合用户节水情况,实施阶梯水价。该研究为农业水资源管理和水价综合改革提供参考。Water prices are closely linked to agricultural water saving and farmers’ interests. Reasonable agricultural water prices can reduce the use of water resources,and improve the efficiency of water use and achieve the purpose of saving water. Based on the water footprint theory,the water footprint of crop production is calculated in 75% hydrological year in Boai Country. Under the condition of avoiding waste and incomplete irrigation,the irrigation water consumption of crops is calculated.The results show that the water footprint of wheat products is0.632 m3/kg,and that the maize products is 0.622 m3/kg. The blue water footprint is converted into basic water price,and the basic water price is 0.23 Yuan/m3,namely basic electricity charge 1.33 Yuan/k Wh. At the same time,it can be combined with farmers’ water-saving situation. The implementation of ladder water pricescan be put into practice. This study provides a reference for the comprehensive reform of agricultural water resources management and water price.
