中文摘要：

文章应用HSPF模型对潮河支流大阁河流域进行径流量模拟，采用大阁水文站1972～1975年逐日流量观测数据，通过参数灵敏度分析和校正，使模拟的流量和实测的数据拟合，对模型进行校正。在此基础上采用1982～1985年逐日流量观测数据对模型进行验证。采用相对误差（RE）以及Nash-Suttcliffe效率系数（Ens）作为模型适用性的评价系数，模拟结果得出流量多年相对误差为0．17、Ens为0．87，表明HSPF模型对研究区流域长期的连续径流量模拟具有较好的适用性。

英文摘要：

Watershed of Dage River, located at the upper of MiyUn Reservoir, was selected as the study area to simulate the runoff by distributed HSPF （Hydrological Simulation Program-Fortran） model. Daily flow data from the year of 1972 to 1975 was used to calibrate HSPF model, by using the parameters sensitivity analysis and correction, the simulated flow and measured data were fitted well. The model was verified by daily flow data from year of 1982＋1985. A relative error （RE） and Nash-Sutcliffe efficiency coefficient were calculated to evaluate applicability of HSPF model, and results showed that HSPF model in the study area has good simulation for long term hydrological modeling.
