【Abstract】 The hydrologic model is used to build a model for simulating and forecasting soil moisture content on the basis of the characteristics of evapotranspiration of different crops during different growth periods,and the relationship between soil layer structure, soil water storage and soil moisture content. The result of simulation shows satisfactory agreement with the observed soil moisture content data in Hongdong county, Shanxi province.更多还原
