| 摘 要： | 在野外试验的基础上，建立了二维农田降雨入渗及产流关系的数学模型，并用中国科学院长武县王东沟农业生态站不同下垫面径流小区实测土壤含水率及产流资料对该模型进行验证。结果显示：该模型对降雨过程中土壤入渗、产流以及雨后蒸发条件下土壤水分的模拟都有很高的精度，可以用于黄土区降雨入渗及产流关系的模拟。 |

| Abstract: | Based on the field experiment, the two-dimensional mathematical model of the relationship between the infiltration and runoff of farmland in the loess region was established. Furthermore, the model was verified with the data of soil moisture and runoff in the different underlying runoff plots at Changwu county, which is one of research stations of Chinese Ecosystem Research Network(CERN). The results showed that the model precison was higher for simulating the soil infiltration and runoff during the rainfall process and the soil moisture during the evaporation after rainfall. The model was used to simulate the relationship between the infiltration and runoff in the loess region. |
