摘要
从土壤水分下渗能力曲线出发，从理论和实验分析两方面说明水土保持措施下土壤入渗性能的改良作用。考虑到流域实际的下渗能力，建立了将下渗能力曲线、不稳定降雨过程和前期土壤含水量有机联系起来的流域场（ 时段） 暴雨地表径流计算模式。
Based on infiltration capacity curve, the paper demonstrates the amelioration of soil infiltration capability under the soil and water conservation measures from theoretical and experimental analysis. Considering that the infiltration capacity curve can't express the actual infiltration capacity, the authors develop the surface runoff yield models that combine with the infiltration capacity curve, unstable raining process and antecedent soil moisture in each rainfall or over a duration time.
