摘　　要：搜集了汾河干流兰村以下各水文站实测历史大洪水资料,分析了洪水在各河段的传播时间及上下游站之间的洪峰流量相关关系,并利用SWAI1模型对历史实测洪水进行了演进分析。结果表明:①受河道断面变化的影响,各河段上下游水文站间洪峰流量对应关系并不理想,在实际的洪水预报中,上下游站洪峰流量关系及其传播时间只能作为参考;②利用累积量法率定参数,采用SWAI1模型模拟的峰现时间合格率均在71.9%以上,洪峰流量的合格率除汾河二坝—义棠段外,均在66.7%以上。Based on collected major historical floods of Fenhe River following Lancun Station, the relationships of flood peak were analyzed either from travel time or among passsing stations, and evolution of historical floods was studied with SWAI1 model also. The results show that：（1） For the fiver section changes, the relationships of peak flow among stations situated on the upper and down streams do not show ideal correlation, so in flood forecast, the peak flow among stations and propagation time are only as a reference; （2） Used eumulant method to quantify parameters, and based on SWAI1 model, the eligible rates of peak appear time simulated are all above 71.9%, the eligible rates of peak flow simulated are all above 66. 7% except the section of Erba--Yitang.
