摘要： 皇甫川流域地处黄河中游典型的多沙粗沙区，该区域的水沙变化对黄河下游水沙情势的改变具有重要指示意义。利用双累积曲线确定1954—2010年皇甫川流域水沙变化的典型时段，对其趋势进行分析，并基于20世纪50年代以来水利水保措施的实施来剖析流域水沙变化的驱动因素。结果表明：皇甫川流域水沙的演变过程可划分为4个典型时段，即1954—1978年、1979—1987年、1988—2002年、2003—2010年。1954—1978年，流域治理度低，受人类活动影响较小，为水沙的自然变化时段；1979—2010年水利水保措施的减水减沙效应不断增大，双累积曲线法计算的减水减沙效应分别为41.8%和49.7%，径流/输沙系数还原法计算的减水减沙效应分别为44.7%和48.3%。

Abstract: Huangfuchuan River watershed is located in the rich and coarse sand area in the middle reaches of the Yellow River. The variation of runoff volume and sediment load in this area has an indicating significance to the change of watersand regime in the lower reaches of the Yellow River. In this study, the typical periods of the variation of runoff volume and sediment load have been ascertained by double cumulative curve and the variation trend of runoff volume and sediment load has been analyzed in the Huangfuchuan River watershed. In addition, the driving factors of the variation of runoff volume and sediment load have been analyzed considering the soil and water conservation measures since the 1950s. The results show that the evolution process of runoff volume and sediment load could be divided into four typical periods, i.e., 1954 to 1978, 1979 to 1987, 1988 to 2002 and 2003 to 2010. During the period from 1954 to 1978, the watershed was slightly affected by human activities and its control degree was low; therefore this period is called natural variation period. The effects of runoff volume and sediment load reduction resulted from soil and water conservation measures have been increasing in the period of 1979 to 2010. The effect of runoff volume reduction reaches to 41.8% and the effect of sediment load reduction reaches to 49.7% by double mass curve method. The values are respectively 44.7% and 48.3% by runoff/sediment coefficient method.
