本文以水量平衡原理、动力学假设以及饱和导水率与有效孔隙度的对数递减模型为基础，提出了一个形式简单的森林流域坡地壤中流模型（以下称为改进模型）。并以二道白河森林流域内阔叶红松林土壤为背景制作模拟坡面，在模拟坡面上用两场不同强度的降雨对该模型进行了验证；同时，本文也分别用Ｓｌｏａｎ所提出的贮水泄流模型（以下称Ｓｌｏａｎ模型）与Ｒｏｂｉｎｓｏｎ所修改后的贮水泄流模型（以下称Ｒｏｂｉｎｓｏｎ模型）对这两场降雨进行了预测，并将这３个模型预测的结果与实测结果进行了比较。结果表明，改进模型精度比其它两个模型高。
Based on the principle of water balance, kinetic assumption, and the logarithmically decreasing model of saturated hydraulic conductivity and effective porosity, a simplified form of mid-flow slope model for forest watershed (hereinafter referred to as improved model) is proposed. The simulated slope was made on the background of the broad-leaved Korean pine forest soil in Erdaobaihe forest basin. The model was verified by two different intensities of rainfall on the simulated slope. At the same time, These two rains are predicted by the water discharge model (hereinafter referred to as Sloan model) and Robinson’s revised water discharge model (hereinafter referred to as the Robinson model), and the results predicted by the three models are compared with the measured results Compare The results show that the accuracy of the improved model is higher than the other two models.
