摘　　要：利用分布式水文模型CREST对淮河史灌河流域梅山水库1978—1987年的入库径流过程进行了参数自动率定和验证,对比分析了实测蒸发数据与全球月平均蒸发数据对径流模拟结果的影响程度,同时进行了蒸发影响效果的误差对比实验.结果表明,采用全球月平均蒸发数据来驱动模型,替代模型运行中所需的实测蒸发数据,具有较好的模拟效果,同时对具有大蒸发面积的流域径流模拟预报效果也较好.The distributed hydrological model CREST was used for the automatic calibration and validation for the parameters of runoff into the Meishan Reservoir,in the Shiguanhe sub-basin of the Huaihe Basin,from 1978 to 1987.The influences of the measured evaporation data and the global average monthly evaporation data on the runoff simulation results were analyzed and compared,and error comparison experiments on evaporation effects were carried out.The results show that using global average monthly evaporation data instead of measured evaporation data during the model operation can produce satisfactory simulation results and can well simulate and predict runoff in the basins that have large evaporation areas.
