摘要
利用宿迁市船行灌区实测数据率定衰减指数平滑模型的参数,研究了衰减指数平滑模型在蔬菜大棚墒情预报中的适用性。结果表明,与霍尔特双参数模型相比,衰减指数平滑模型改善了预报效果,用于蔬菜大棚墒情预报具有较高的精度。
The applicability of attenuation index smoothing model for predicting soil moisture in vegetable greenhouses was investigated.The attenution index smoothing model was calibrated and validated by the measured soil moisture values of vegetable greenhouses in Chuanhang irrigation district,Suqian city.The results showed that compared with the Holt double parameters model,the attenuation index smoothing model provided better predictions and had higher accuracy for predicting soil moisture of vegetable greenhouse.
