Abstract:: This paper statistically analyzes the runoff and sediment transport of the Huangfuchuan river watershed in more sediment and coarse sediment region of the Yellow River, through Several non-parameter statistical methods such as the moving average check, the Mann-Kendall test. The paper concludes that the trend of runoff evolvement and sediment transport at the Huangfu station decreased are very distinct. The major factors correlated with the runoff and sediment transport changes such as the rainfall, soil conservation. With the relationships between rainfall, water and sediment, and the accumulation curves of the mass runoff and mass sediment transport at Huangfu station. The sediment descending proportions caused by the reduction of rainfall and soil conservancy are respectively evaluated.
