| 摘 要： | 针对降雨、蒸发蒸腾量的随机性,在制定作物灌溉计划时,将降雨、蒸发蒸腾量进行随机化处理,采用基于时间序列的随机水文学方法对降雨和蒸发过程进行了模拟,将随机模拟出的降水、蒸发蒸腾结果代入水量平衡方程,从而确定灌溉时间和灌水量。经过和实测序列进行对比,模拟值和实际值拟合较好,最大误差仅为4.74%,可为科学制定作物灌溉计划提供参考。

| Abstract: | Aiming at the randomicity of precipitation and evapotranspiration in the formulation of crop irrigation schemes,the precipitation and evapotranspiration were randomly treated,and simulated using random hydrology methods based on time-series.The simulated values were used into the water balance equation to determine the irrigation time and amount,and compared with the measured sequence.The result indicates that the simulated values and actual values fit well,the maximum error was only 4.74%.It can provide a ... |
