摘要
以黄河干流宁蒙大型自流引黄灌区为研究对象,采用分项法以及两种计算顺序对宁蒙引黄灌区田间节水潜力进行了计算,分析了不同计算顺序对田间节水潜力计算结果的影响,并采用综合法对分项法计算结果进行了验证,表明计算方法可靠。
Taking the large-scale gravity irrigation districts in main stream of Yellow River in Ningxia and Neimenggu as study object, this paper applied subentry method and two kinds of calculation orders to calculate the field water-saving potential in irrigation districts of Yellow River in Ningxia and NeiMengGu, analyzed the influence of different calculation order on the calculation result of field waterr-saving potential. Also, the author applied synthesis method to validate the reliability of calculation result of subentry method.
