摘　　要：为了满足邢台市平原区农业合理利用水资源的需求,基于宁晋县艾辛庄站的2003—2020年的土壤墒情监测数据,采用消退系数法模型建立适合于该区域的含水量预测模型,而且通过实测数据验证模型的准确度。结果表明,该模型预测的土壤含水量与实测土壤含水量误差仅为1.3%,具有良好的预测效果。该模型能够为此区域合理调节土壤湿度提供一定的理论参考。In order to meet the new demand of agricultural rational utilization of water resources in the plain area of Xingtai City,based on the monitoring data of soil moisture at Aixinzhuang Station in Ningjin County from 2003 to 2020,a water content prediction model suitable for this area was established by using the regression coefficient method model,and the accuracy of the model was verified by the measured data.The results show that the error between the predicted soil water content and the measured soil water content is only 1.3%,which has a good prediction effect.The model can provide a theoretical reference for the rational regulation of soil moisture in this region.
