| 摘 要： | 采用灌溉水利用系数、灌溉效率和水分生产率3种指标,结合石津灌区2004~2005年冬小麦生育期内的耗水量和产量,从灌区管理与水资源利用的角度,评价了该灌区农业水资源的利用状况。同时运用地下水位观测资料分析计算了田间渗漏水量和垂向回归水量,定量分析了垂向回归水补给量对灌溉效率的影响。经计算,灌溉水利用系数为0.476、灌溉效率平均为0.667、灌溉水分生产率不同尺度分别为1.214、1.350、1.490、1.751 kg/m3。回归水的再利用使得灌溉效率值平均提高了18.8%。

| Abstract: | In order to evaluate the agricultural water use efficiency in Shijin Irrigation District,water management data and wheat yield data in 2004~2005 were used to calculate conveyance efficiency,irrigation efficiency and water productivity.Groundwater observation data were used to determine the amount of reused percolated water and its effect on irrigation efficiency.The results show that the conveyance efficiency is 0.476,the average irrigation efficiency is 0.667,and water productivity in different scales are ... |
