在水文资料中，特别是在灌排规划资料中，需要对蒸发速率进行估算。粮农组织推荐的估算蒸散速率的方法是Penman - Monteith方法，但除了该方法之外，如果实地获得的数据不同，还可以使用几种方法。对估算蒸散发速率的方法进行评价，可以帮助在获得不同数据时选择正确的方法，因此通过评价，我们可以看到方法的准确性。与Penman - Monteith方法最接近的方法是Hargreaves， Makkink, Turc， Blaney-Cridlle和Penman。如果按照评价结果的排序，最接近Penman - Monteith方法的是Hargreaves方法，因为在所有评价变量中，Hargreaves具有最好的评价价值。而基于最佳R2值的最接近的模型是Jensen-Haise模型，但该模型的误差值非常高。
Estimation of evaporation rate is needed in hydrological data, especially in irrigation and drainage planning data. The method for estimating the evapotranspiration rate recommended by FAO is the Penman - Monteith method, however apart from this method there are still several methods that can be used if the data obtained in the field are different. Evaluation of the method of estimating the rate of evapotranspration is expected to help in choosing the right method when different data is obtained, so with this evaluation, we can see the accuracy of the methods. The methods that are closest to accuracy with the Penman - Monteith method are Hargreaves, Makkink, Turc, Blaney-Cridlle and Penman. If ordered based on the ranking of the evaluation results, the method that is closest to the Penman - Monteith method is Hargreaves, because of all the evaluation variabels Hargreaves has the best evaluation value. While the closest model based on the best R2 value is the Jensen-Haise model, but the error value of this model is very high.
