| 摘 要： | 应用Green—Ampt修正方程及运动波方程,构建了天然降雨条件下的黄土区均匀坡面水文预报模型,并利用野外天然降雨径流实测资料进行了验证。结果表明,总径流量预报相对误差在20%以下,预报径流过程与实测径流过程吻合很好,坡面水文模型可以较好地模拟黄土地区天然降雨条件下的均匀坡面水文过程。同时也指出,应深入研究复杂坡面上的水文预报模型,进一步完善黄土区坡面水文模型。

| Abstract: | Applying modified Green-Ampt equation and kinematic wave equation and using observed rainfall and runoff data,hydrology model of uniform loess hillslope was built up and validated.Results showed that relative effor of runoff volume was under 20% and predicted runoff hydrograph accorded well with observed runoff hydrograph,which means that hydrology model on loess hillslope brought out by this thesis can be used in simulating hydrology processes produced by natural rain on uniform loess hillslope.At the same time,it was pointed out that hydrology prediction model of complicated hillslope should be studied and that hydrology model of loess hillslope should be improved. |
