摘　　要：针对利用马卡维耶夫法计算造床流量繁琐的问题,采用地貌功图解法简化计算造床流量,并基于黄河下游花园口、高村、艾山、利津4个水文站1960~2014年实测水沙数据,通过马卡维耶夫法与地貌功图解法分别计算4站历年造床流量。结果表明,两种方法所计算的黄河下游4站历年造床流量差异较小且下降趋势相近,地貌功图解法相比马卡维耶夫法计算造床流量更简便、准确。Aiming at the cumbersome problem of applying the Markaviev method to calculate the bed-forming flow rate,the geomorphic work diagram method was proposed to simplify the calculation of the bed-forming flow.Based on the measured water and sediment data from 1960 to 2014 at the four hydrological stations of Huayuankou,Gaocun,Aishan and Lijin in the lower reaches of the Yellow River,the Markaviev method and the geomorphological method were used to calculate the bed-forming flow of the four stations over the years.The results show that the differences in the bed-forming flow over the years at the four stations in the lower reaches of the Yellow River calculated by the two methods are small and the downward trend is similar.Compared with the Markaviev method,the geomorphic work diagram method is more convenient and accurate to calculate the bed-forming flow.
