- 摘要:
- 土壤水分的动态模拟是土壤墒情监测及预报的重要内容，采用时间序列的线形模型进行土壤水分时间序列的拟合与趋势预测。在建立模型后，用实测数据与模型的预测数据相比较说明时间序列线形模型能较好地拟合与预测土壤墒情的变化趋势，可为干旱研究及其治理提供依据。
- Abstract:
- Soil moisture dynamics simulation is an important item of soil moisture monitoring and forecasting.In this paper, time series analysis linear model is used to forecast the change trend of soil moisture.By comparing the measured value with the estimated value,it is showed that the time series analysis linear model can preferably fit soil moisture time series, and provides a foundation for the drought research.
