| 摘要: |
| 通过对石头河流域降雨径流关系的分析，选取斜峪关水文站1954～1978年的61场典型洪水，建立了该流域蓄满产流模型，模型评定的合格率为91％，确定性系数为0.890；并用1979～1980年斜峪关水文站的10场典型洪水对模型进行了检验，合格率为70％，确定性系数为0.921，均达乙等预报方案。 |

| Abstract: |
| Based on 61 typical flood data from 1954 to 1978 at Xieyuguan Hydrologic Station,the paper analyzes the relationship between precipitation and runoff,and develops a runoff forecasting model.The qualified ratio of evaluating the model is 91% and deterministic coefficient of evaluating the model is 0.890.The paper tests the model using 10 typical flood data at the station from 1979 to 1980,the qualified ratio is 70% and deterministic coefficient is 0.921.The forecasting results of the model are the second standard level. |
| Key words: Shitouhe watershed runoff forecasting forecasting model |
