摘要
针对土壤水分含量的非平稳随机特性 ,建立了预报丘陵旱坡地土壤水分动态的季节性时序模型。用该模型对 0～ 30cm和 2 0～ 30cm土层的水分含量长期预报进行了探讨 ,结果表明 。
Taking into consideration the non-stationary and stochastic nature of soil water content, a seasonal time series model was developed for predicting the dynamics of soil water content on dry slope land in hilly regions. The model was applied to the prediction of the dynamics of soil water content in 20～30 cm and 0～30 cm layers. The predicted values of soil water had a good agreement with measured data.
