通过野外测定获得黄土丘陵坡地不同土地利用结构的表层土壤水分, 依据影响该区土壤含水量的重要因素是坡度、土地利用、植被覆盖以及地表水的扩散特征, 建立了黄土丘陵坡地的土壤水分空间分布模型. 应用野外测定的土壤水分值进行模型的参数拟合, 采用有限元方法正解模型, 对黄土丘陵坡地土壤水分的空间分布进行模拟, 并与实测值进行了比较. 结果表明, 该模型具有较好的拟合效果. The surface soil moisture of different land use structures in loess hilly slopes was obtained by field measurement. According to the characteristics of slope, land use, vegetation cover and surface water diffusion, the soil water content Distribution model.The soil water content in the field was used to fit the model and the finite element method was used to simulate the spatial distribution of soil moisture in the loess hill slope.The results showed that this model Has a good fitting effect.
