摘　　要：为了对新疆东部中型灌区田间水利用系数进行测算,首先进行田间水利用系数进行测算,然后对田间测定结果汇总计算得出中型灌区田间水利用系数。结果表明:田间水利用系数随时间变化呈"反S型"趋势,在7月上旬至7月下旬时间段内有明显降低;土壤质地、灌溉方式的不同会造成田间水利用系数的差异;对田间测定结果汇总计算得出新疆东部中型灌区田间水利用系数为0.852。为灌区田间水利用系数的测算提供了较好的方法,同时也为灌区农业高效节水提供了技术依据。In order to calculate the medium irrigation district field water utilization coefficient of Eastern Xinjiang,the coefficient of field water utilization is first calculated,and then the field water utilization coefficient of the medium-scale irrigation district is calculated. The results show that the field water utilization coefficient shows a trend of＂anti-s-s-type＂over time and decreases significantly in the period from early July to late July. The difference between soil texture and irrigation method can result in the difference between water utilization coefficient in the field. The field water use coefficient of medium-sized irrigated district in eastern Xinjiang is 0.852. This paper provides a good method for calculating the coefficient of field water utilization in irrigation districts,and also provides technical basis for the efficient water-saving agriculture in irrigation districts.
