摘　　要：河道水情信息为流域防汛减灾、水资源管理保护、流域安全提供最基础的数据,是水文工作的灵魂。选取汾河上游的静乐至河岔河道为研究对象,采用马斯京根法和衰减分析法两种方法,对该区间洪峰传播及其衰减幅度进行分析。结果表明:在所选静乐到河岔河段9场洪水中,马斯京根和流量衰减分析法计算的洪峰衰减相对误差分别为0.22和0.25,二者计算结果比较接近。可为汾河上游河道水情监测、防洪减灾、水资源开发利用提供一定的借鉴。River water regimen information provides the most basic data for flood control and disaster reduction,water resource management and protection,and river basin safety,and is the soul of hydrological work.This study selected the Jingle to Hecha river channel in the upper reaches of the Fenhe River Basin as the research object,and used two methods,the Muskingen method and flow decrease analysis method,to analyze the propagation and decrease amplitude of flood peaks in this interval.The results show that among the 9 selected floods in the Jingle to Hecha section,the relative errors of peak decrease calculated by Muskingen and flow decrease analysis methods are 0.22 and 0.25,respectively,and the results obtained by the two methods are relatively close.The study can provide a certain reference for monitoring the water regime,flood control and disaster reduction,and water resource development and utilization in the upper reaches of the Fenhe River Basin.
