Based on the daily rainfall data of 145 meteorological stations in the Yellow River basin, the spatial and temporal variations characteristic of erosive rainfall was analyzed by using statistical methods. The results show that the trend of the erosion precipitation, extreme precipitation and annual precipitation is significantly reduced. The erosion precipitation, extreme precipitation and annual precipitation are decrease from southeast to northwest. The long-term trends of different intensities rainfall is non-uniformity in space nearly 50 years. The erosion precipitation and annual precipitation are increasing in most areas of the upper reaches of the Yellow River basin, and are decreasing in the others areas, especially decreasing significantly in the water and soil loss of serious erosion in the Loess Plateau.
