摘　　要：本文采用相关分析与GAS参数优化相结合的方法,对黄河上游非汛期径流预报模型进行了研究,并对2000～2003年的径流进行了实时预报检验,从检验结果来看,这种预报方法具有较高的预报精度。本文为非汛期径流预报研究提供了参考和借鉴,同时,就计算分析手段而言,GAS在参数优化方面具有广泛的应用价值。Combining correlation analysis and GAS parameter optimizing, this paper studied on the model of medium and long term runoff forecasting for the Yellow River in non-flood season, and made forecast checking. The results show that this kind of forecasting methods have a higher precision. This paper offered reference to study on medium and long term runoff on the Yellow River. As for as the analysis method, GAS has extensive practical value in parameter optimizing.
