摘　　要：选用基于Source平台的SIMHYD模型进行祖厉河流域的降雨径流模拟。采用1956—1985年靖远站实测径流数据进行参数率定,并采用1986—2000年的数据进行模型验证。结果表明,多年平均径流量及最大、最小日平均径流量计算值分别与实测值相差-8.6%、0.2%、-20.1%,相关系数为0.98,Nash效率系数为0.96。SIMHYD模型总体模拟结果较好,可以满足模型精度要求。采用更为准确的降雨、蒸发和用水资料,进一步率定优化参数,可以提高模拟结果。SIMHYD is a rainfall-runoff model integrated in the Source. This model is applied to simulate the rainfall-runoff in Zuli River basin. The measured runoff data of Jingyuan Station from year 1956 to 1985 was used for calibration of the parameters of Zuli River basin rainfall-runoff modeling and the measured runoff data of Jingyuan Station from year 1986 to 2000 was used for validation of the modeling. The modeling result indicates that the SIMHYD model is applicable for Zuli River basin from the following aspects: a) the difference of the average,maximum and minimum runoff between the calculated results and the measured results are-8.6%,0.2% and-20.1% respectively; b)the coefficient is 0.98 and; c) Nash Sutcliffe efficient is 0.96. The modeling results can be improved by more accurate precipitation,evaporation and water consumption data.
