| 摘 要： | 径流输沙模型对定量评价水沙的输出响应具有重要的意义。本研究在已有研究成果的基础上，通过对四川盐亭县林山西沟小流域的径流、泥沙进行现场观测与分析，提出含沙量单位线的定义及其确定方法，建立了适应该小流域的径流输沙模型。并应用实测资料进行比较，表明模型的模拟结果可靠，模拟过程确定性系数达0．8以上，为川中丘陵区小流域径流输沙过程的预测预报提供了一个新方法。 |

| Abstract: | Runoff and sediment transport model is important to quantitatively evaluate the environment response to water and sand. On the basis of the previous research, the definition and the determination method of sediment concentration unit curve is proposed and a model for simulating runoff and sediment transport in small watersheds is developed. The simulated results by the model agree with the measured data very well and the deterministric coefficient reaches over 0.8. It is expected that the proposed method can be used to simulate the sediment transport process of the small watershed in the Central Hills of Sichuan. |
| Keywords: | purple soil runoff and sediment transport small watershed sediment concentration unit curve process simulation |
