摘要: Reference evapotranspiration (ETo) data are the great important information for the irrigation scheduling design and regional water resources planning. This study evaluated the potential of a newly proposed artificial intelligence (i.e., DeepFM) and three newly developed gradient boosting models (i.e., CatBoost, LightGBM, and XGBoost) for estimating daily ETo using limited meteorological parameters in contrasting climates of China. The three commonly used tree-based models (i.e., GBDT, RF, and ET) and one kernel-based model (i.e., SVM-RBF) were also assessed for comparison. Eight various input combinations of meteorological parameters (temperature, humidity, wind speed, and sunshine duration) from twelve stations during 1961-2016 in contrasting climates of China were employed for model training and testing. The results showed that all models (except ET) could obtain satisfactory prediction accuracy (R2 >= 0.9906, RMSE <= 0.1773 mm d-1, and MAE <= 0.1226 mm d-1) for ETo estimation in contrasting climates of China when complete meteorological parameters were input. Moreover, all models can be sorted from the best to the poorest as follows based on the model accuracy: CatBoost > LightGBM > XGboost > GBDT > SVM-RBF > DeepFM > RF > ET; regarding their stability, the eight algorithms can be ranked from the best to the poorest as follows: ET > SVM-RBF > DeepFM > CatBoost > XGboost > GBDT > LightGBM > RF. Therefore, considering the prediction accuracy and model stability comprehensively, the CatBoost and LightGBM models were highly recommended for predicting daily ETo in this study. The XGBoost and GBDT models were promising alternative models for estimating daily ETo. The DeepFM model also had the potential to estimating daily ETo under single variable combinations. The sunshine duration played a more important role than temperature, humidity, and wind speed in estimating ETo, and it was a promising alternative parameter under the circumstances of lacking global radiation observation.
