摘要
运用平原水文模型 ,参考不同作物不同生长期蒸散发特点及土层结构和土层蓄水量与土壤墒情之间的关系 ,构建区域土壤墒情模型 ,并利用山西省洪洞县实测土壤墒情资料对该模型进行了检验 .检验结果表明 ,模型物理概念明确 ,可连续模拟或预报区域土壤墒情 。
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.
