摘　　要：水文模拟对于流域防洪减灾、水资源规划管理有重要的意义。将分布式水文模型HEC-HMS应用到北京温榆河流域,模拟该区域1980-2005年间6场暴雨洪水过程和1983-1995年日降雨径流过程,评估HEC-HMS模型在模拟场次洪水和日径流过程两种时间尺度上的适用性。结果表明,场次洪水模拟的洪峰流量和洪量相对误差均在20%以内,峰现时差均不超过2h,平均Nash效率系数为0.82,平均相关系数r为0.92;日径流模拟率定期和验证期的平均Nash效率系数为0.6,平均相关系数r为0.78,平均相对误差为3.95%。分析结果表明,HEC-HMS模型在温榆河流域的适用性较好,能够有效模拟北方地区短时和长时降雨径流过程,可用于该区域的洪水预报和水资源评价与管理。Hydrological simulation is important for flood hazard mitigation and water resources management.In this study,we adopted the distributed hydrological model HEC-HMS to simulate the flood events and daily runoff of the Wenyu River basin in Beijing,China.The model was calibrated and validated with the data of 6 storm events during 1980-2005 and daily stream flow during 1983-1995.The results showed that for all of the 6 floods,the relative errors of peak flow and runoff amount were less than 20%,and the peak time difference was within 2 h.The average Nash efficiency coefficient and average correlation coefficient r were 0.82 and 0.92,respectively.For the daily runoff simulation,the average Nash efficiency coefficient was 0.6,the average correlation coefficient r was 0.78,and the average relative error was 3.95%.Preliminary analysis showed that the HEC-HMS model applied well to the Wenyu River basin.It can effectively simulate the short-term and long-term rainfall and runoff processes in northern China,and can be used for flood forecast,water resources evaluation and management in this area.
