摘　　要：依据对2012年麻地壕灌区的实际调研,通过选取典型渠道和典型田块,并对其进行渠道水利用系数和田间水利用系数的测算,采用综合测定法对灌溉水利用系数进行测定,所选典型渠道测试法测得的结果0.472与根据首尾测算法校核的结果0.478相近,故能得出此法在该灌区具有较高的实践价值。Based on the 2012 actual research of Madihao irrigation, the typical channels and typical fields are selected and channel wa- ter utilization coefficient and field water utilization are estimated. Then the comprehensive measurement method is used to calculate the irrigation water use coefficient. According to the outcomes, we can see the result of selecting typical channel is 0. 472. It is close to the head-end measurement method whose result is 0. 478. So it has a high practical value for irrigation.
