摘　　要：选取陕西省洛惠渠洛东自流灌区,东雷高抽引黄河水灌区进行监测分析地表水耗水系数,结论是:洛东灌区明渠耗水系数为0.825,东雷抽黄一期塬上接近1,东雷二期为0.91,东雷灌区一、二期耗水系数为0.927;按灌溉面积加权推算,陕西省黄河流域灌区有效面积计算的综合耗水系数为0.862,实灌面积计算的综合耗水系数为0.868;结合通过地下水回归河道,则洛东灌区耗水系数为0.769,陕西省黄河流域灌区有效面积计算的综合地表水耗水系数为0.825,实灌面积计算的综合地表水耗水系数为0.834。The surface water consumption coefficient of Luodong River irrigation area and Donglei High-pumping Yellow River irrigation area in Luohui canal in Shaanxi province were monitored and analyzed.The conclusions are as follows:the water consumption coefficient of Luodong irrigation area is 0.825,the one-stage plateau of Donglei drainage area is close to 1,the second stage of Donglei irrigation is 0.91,and the first and second stage of Donglei irrigation area is 0.927.According to the weighted calculation of irrigation area,the comprehensive water consumption coefficient of the effective area of the Yellow River Basin in Shaanxi province is 0.862,and the comprehensive water consumption coefficient of the actual area is 0.868.Combined with groundwater regression to the river course,the water consumption coefficient of Luodong irrigated area is0.769,the comprehensive surface water consumption coefficient calculated by the effective area of the Yellow River Basin in Shaanxi province is 0.825,and the comprehensive surface water consumption coefficient calculated by the actual irrigated area is 0.834.
