The revised Hargraves formula has the best result compared with Penman-Monteith formula, the average relative error is 6%, moreover, Hargaves method requiring the least data in calculating ETo, so this method has the high actual application value; The following are Radiation method and Blaney-Criddle method ; The worst is the Pan method, even after revised, the highest and average relative error is 36% and 10%, respectively. So, in this study, Penman-Monteith method, Radiation method, Blaney-Criddle method and Hargraves method are used except Pan method.
在这四种方法中,修正后的Hargraves方法与彭曼—蒙特斯方法的计算结果符合最好,其平均相对误差为6%,而Hargraves方法需要的气象数据只有计算时段的最高、最低温度,该方法具有较高的实际应用价值;辐射方法和布兰尼—克里德尔方法次之;蒸发皿方法最差,即使在修正后,E601型蒸发皿的最大误差也高达36%,平均为10%,所以在预报系统的研究设计中采用了除蒸发皿方法之外的四种方法。
