摘　　要：在对甘肃省洮惠渠灌区和典型地块进行引退水监测试验的基础上,采用引排差法开展不同尺度耗水系数率定工作。结果显示,灌区和典型地块2016年耗水系数分别为0.721和0.571。灌区和典型地块耗水系数表现出一定的尺度效应,灌区尺度上耗水系数明显高于典型地块尺度。Based on the monitoring experiment on the water diversion and return in Taohuiqu irrigation area and typical plots in Gansu Province, the water consumption coefficient at different scales was calculated by diversion and discharge difference method. The results showed that the water consumption coefficients of irrigation area and typical plots in 2016 were 0.721 and 0.571 respectively. The water consumption coefficients of irrigation area and typical plots showed a certain scale effect, and the water consumption coefficient in irrigation area was obviously higher than that of typical plots.
